Fast antiviruses that don't slow down the system: full review. Antivirus engines

360 Total Security is a modern free antivirus from Qihoo with full protection against all types of threats in real time, a Sandboxi virtual environment with additional system optimization and cleaning functions.

Qihoo introduced its powerful product 360 Total Security, which replaced the previous version of the comprehensive antivirus 360 Internet Security, it also used several antivirus engines to protect the computer, including its own cloud-based developments, which have proven themselves. In the new product, the number of engines has increased to five. All of them are reliable, powerful and time-tested: QVM II (responsible for proactive protection), 360 Cloud (cloud protection), System Repair (system vulnerability analysis and recovery), BitDefender, Avira AntiVir, the last two can be enabled and disabled at will ( by default, they are disabled after installation). The load on the system has been optimized, allowing you to hardly notice the antivirus running.

The pleasant and friendly interface of 360 Total Security is implemented in the style of Windows 8. There should be no difficulties in operation and maintenance, everything is intuitive. The range of possible settings is quite sufficient to tailor the operation of the antivirus to your own needs. Everything is in its place and easy to find.


The level of protection is easily adjusted in the corresponding “Protection” menu, which is called up by clicking on the large icon (where it says “protection: on”) and then “Settings”. The user can select a level from ready-made rule sets or set their own, enabling or disabling selected protection modules: whether to use the BitDefender and Avira AntiVir antivirus engines, conditions for scanning files (when saving or also every time they open), whether to use behavioral analysis, scanning files when downloading from the Internet, enable or disable banking protection and other functions. The default mode is balanced, providing optimal load and protection.


From the settings menu, you can additionally install the 360 ​​Web Threat Protection plugin, which identifies malicious links and sites based on the cloud link database from the 360 ​​Cloud Security Center. The web protection plugin does a very good job of protecting against malicious, phishing (fake) and fraudulent sites. In the Tools menu, you can additionally install a firewall (firewall) GlassWire, which is reliable and easy to configure rules, unlike other firewalls designed for good user preparation. There you can also add a system file compression module, a browser web protection plugin, set up a sandbox and fix system vulnerabilities.


It has its own safe virtual environment - Sandbox, in which you can safely run any program; by the way, Windows 8.1 is supported. You can configure the automatic launch of certain programs in such a Sandbox environment, so that at any time you can remove all traces of the dangerous program, as if it had never been launched at all, since Sandbox is an isolated environment and operates separately from the main system, without making changes to it.


You can selectively launch programs in the sandbox from the Explorer context menu. You can also remove programs and all their sandbox data manually or in accordance with the rules in the Sandbox settings, for example, automatically clearing the sandbox on reboot.

One of the key changes to 360 Total Security is the addition of system cleaning and optimization features, at least to the extent required to increase computer protection. Moreover, the cleaning and acceleration function allows you to do this in one click with the largest button of the main program window, or carry out these operations sequentially separately in the appropriate sections. For example, accelerating and optimizing system operation:


Finding and solving problems with system vulnerabilities:


When performing such actions, it is advisable to carefully look at what is being deleted or corrected there, so as not to delete something necessary.

You can also manage the antivirus through the context menu in the system tray (the icon on the panel below next to the clock).

360 Total Security is, first of all, an excellent computer protection tool, a powerful antivirus with a high level of protection, based on several antivirus engines and web protection extensions, as well as a built-in safe Sandbox sandbox virtual environment. With all this, it is very easy to use and pleasant to work with.

Qihoo has begun to additionally release a lightweight version of the antivirus without optimization and acceleration elements - . This product contains only antivirus components, that is, all antivirus engines, including BitDefender and Avira, as well as a sandbox. Russian-language interface is also supported. Many people like the lighter version better.

Quite often on the Internet there are questions about which antivirus loads the system the least, which one is suitable for a weak computer and at the same time will fully perform its main function. There are many different ratings and lists, but they all differ significantly from each other and cannot give users a definite answer.

Therefore, today we will look at the best antiviruses that do not load the system, suitable for weak PCs, and you will choose the most optimal one for yourself.

When compiling this list, we relied on the following characteristics:

  • Processor: 0.5 – 1.5 GHz.
  • RAM: 128-256MB.
  • Hard drive space: 15-300MB.

Previously there was a similar article about antiviruses for weak machines, but in it we analyzed the defenders, starting from a larger amount of RAM (256MB-1GB) and processor (from 1.5GHz). If your PC or laptop exceeds these specifications, we recommend that you familiarize yourself with it.

All proposed solutions have their advantages and disadvantages, and also differ in system requirements. Let's take a closer look at each, its features and functions.

AhnLab V3 Internet Security

A Korean antivirus that loads the system the least and provides effective computer protection while consuming a minimum of system resources. It has all the features to maintain complete security, protects against malware and prevents the installation of spyware.



The program protects your laptop or PC in real time, filters sites with dangerous content, attachments in emails, and optimizes system performance. The utility operates on cloud technology and is characterized by a minimum number of false positives. The additional TrueFind function helps to detect the removal of even hidden rootkits in a timely manner.

The utility has the following system requirements:

  • Processor – from 0.5 GHz and above.
  • RAM – from 256MB.
  • Free disk space – from 300MB.
  • Supports OS from Windows XP to Windows 10.

Based on the available data, we can say with confidence that the antivirus does not slow down the system. In addition, the utility removes unused data and other garbage to improve performance and normalize work.

ClamWin Free Antivirus

Another free solution that is freely available on the Internet. It would be more correct to call this utility a scanner, since it does not have a scanner that constantly checks the files being used. This means that if you want to find a virus, you must manually run a file scan.



The program has a clear interface, rich functionality and a number of different settings. There are also additional functions, such as scanning at a time you set, notifications about malware detection, automatic database updates, and easy integration into the Windows menu makes it more accessible.

If we talk about system requirements, they are as follows:

  • Processor – 1.5 GHz.
  • HDD – 103MB.
  • RAM – 256MB.
  • Compatible with Windows XP/Vista/7/8/10.

That is, the presented anti-virus scanner consumes a minimum of resources and in no way slows down the computer.

SMADAV

An excellent antivirus that acts as additional protection against malware. It is the second line of defense and is fully compatible with any other antivirus utilities. The program uses heuristic and behavioral analysis to detect and eliminate viruses as quickly as possible. This is what ensures a high level of security. Due to the small amount of resources used, the utility does not reduce performance even with active use.



It has a range of effective tools. To begin with, it’s worth talking about standard scanning, which comes in 3 types:

  • Fast.
  • Complete.
  • Scanning the system area.

In addition, SMADAV is equipped with a system editor, with which you can select specific elements, they will be displayed in Start, and disable system applications. It is also worth paying attention to the process manager, which allows you to view running processes and, if necessary, terminate them.

System Requirements:

  • Processor: Intel Pentium III or higher.
  • RAM – 256MB.
  • Hard disk – 100MB.
  • Works on all Windows OS.

Considering its characteristics, this is an excellent antivirus program that does not slow down the system or reduce the performance of the computer.

Webroot SecureAnywhere AntiVirus

Panda Antivirus Free

Cloud antivirus with low system load and reliable real-time protection. The program combines remote and local antivirus, anti-rootkit and anti-spyware. The cloud model does not require a large amount of resources and does not affect the functionality and performance of the system. Moreover, this operating principle allows you to detect and block malware more efficiently and quickly.



It should be understood that an antivirus can slow down your computer only if there are not enough PC resources for its correct operation, so when choosing security software, always take into account the characteristics of your device.

Creating a reliably operating information system of any level of complexity is impossible without the use of special means of protection against computer viruses. Such protection is especially relevant today, when more and more computers are networked and connected to the Internet. Miscalculations made when organizing anti-virus protection can lead not only to temporary disruption of computer systems, but also to irreparable data loss.

When a regular antivirus is powerless

The first viruses were spread through program files and boot sectors of floppy disks, so it is not surprising that most anti-virus programs are designed specifically for scanning files. Today, the main channel for the spread of computer viruses is office document files transmitted via email. Therefore, file scanning is one of the most important means of anti-virus protection.

However, those of you who limit themselves to using only conventional file antiviruses are at great risk. File antiviruses are not able to detect malicious code, for example, in data streams passing through Internet channels and in databases of information and computing systems.

In addition to file antiviruses, there are also specialized antivirus programs that can filter data flows passing through email servers, firewalls and proxy servers. There are anti-virus solutions for document management systems such as IBM Lotus Notes and Microsoft Exchange.

However, there are a large number of “non-standard” information systems, servers, services and programs for the protection of which it is impossible to use ready-made antiviruses. As an example, we can cite various accounting information systems, automation systems for document flow and various activities of enterprises, warehouse and accounting systems, etc. The use of conventional antiviruses to protect such systems may be ineffective, because They use databases rather than files to store documents.

Realizing the relevance of anti-virus protection, the creators of information computing systems and Internet services are looking for various ways to solve the problem using conventional file anti-viruses. For example, the Merak Mail Server (http://www.icewarp.com) can scan mail passing through it using almost any external anti-virus program that can operate in batch mode. During the scanning process, attachment files of mail messages are copied into temporary files, which are then scanned by the antivirus.

It should be noted that the use of temporary files and external antivirus programs is not the best solution, and in some cases this technology is completely unsuitable. Creating temporary files wastes computer resources, which slows down data processing. Temporary files will also be very ineffective for inspecting Internet traffic passing through firewalls or proxy servers.

Antivirus engine licensing

Meanwhile, software developers can build an anti-virus engine into their own programs and software systems. To do this, they need to purchase a license for the anti-virus engine and anti-virus databases from one of the anti-virus companies.

Having a license to use the anti-virus engine in their own developments, software creators will be able to use it with maximum efficiency. The anti-virus engine can be built into almost any information system or program that processes documents or files.

For example, as the creator of a data archiving and backup utility, you can scan all copied files, excluding computer viruses from entering data archives or restoring infected files from this archive.

By creating your own Internet service, such as an email server, a firewall, a proxy server, or a Web site for distributing shareware and freeware, you can effectively protect it from computer viruses. In this case, you will not have to resort to various tricks such as creating temporary files and connecting external anti-virus programs.

With a license to use the antivirus engine, you can even release your own antivirus program. Such a program will combine powerful anti-virus protection tools developed by professionals in this field, and other additional features not found in conventional anti-virus programs. It can implement, for example, a user interface in any national language, carry advertising for your company, perform any additional checks or have additional capabilities.

Examples of antivirus engine integration

Below we will give some successful examples of the integration of domestic anti-virus engines on a licensing basis into various programs and systems.

Based on an agreement reached between JSC DialogNauka (http://www.dials.ru) and FSUE NPO Mashinostroeniya, the kernel of the famous Doctor Web antivirus was used to protect a document management system created on the basis of Sapiens’ own technology (http:// www.npomit.ru). All information stored by this system in the database is checked by the Doctor Web anti-virus engine.

One of the activities of FSUE "NPO Mashinostroeniya" is the creation of information systems for federal authorities, public organizations, public and private companies, as well as the provision of services in the information technology market. "NPO Mashinostroeniya" is the lead developer of the Integrated Information and Computing System (IICS) of the Ministry of Industry and Science of Russia and the IICS of the State University Higher School of Economics.

As developers of information systems for responsible use, NPO Mashinostroyenia has provided anti-virus protection for such of its developments as Sapiens Registration and Control of Document Execution, Sapiens Monitoring of Computing Resources, Sapiens Electronic Archive of Design Documentation.

Another successful example of licensing the Doctor Web antivirus core is anti-virus scanning in the DIONIS email system, created by the domestic company FACTOR (http://www.rospac.ru/dion.htm). This system is used, in particular, for processing postal correspondence within the State Automated System "Elections" system, as well as in the Ministry of Taxes and Duties.

If you are developing a Web projector, then by owning a license for the anti-virus engine, you can create your own anti-virus service on the Internet. An example is the Defender antivirus, created by the American company eAcceleration.com using the Doctor Web core. This antivirus is designed to scan files on-line (Fig. 1).

Rice. 1. Defender Antivirus from eAcceleration.com

Probably many of you have had to burn CD-R or CD-RW CDs. These disks are very convenient for creating backups and archives. The German company Ahead Software (http://www.nero.com) has integrated the Doctor Web anti-virus engine into its Nero Burning ROM program (Fig. 2). This allows you to protect the created archives from computer viruses without installing additional anti-virus programs. Nero Burning ROM can update the anti-virus database via the Internet, which is necessary for effective anti-virus protection.

Rice. 2. Built-in anti-virus scan in Nero Burning ROM

Based on the Doctor Web core, the Chinese company Kingsoft (http://www.iduba.net) created its own iDuba.net antivirus (Fig. 3).

Rice. 3. iDuba.net antivirus with Chinese user interface

Based on the Doctor Web core, a plugin has been created for the popular email program The Bat!. It ensures that each message or attachment is processed based on the result of an anti-virus scan and provides anti-virus protection for the mail system, even if the resident guard is disabled or not installed. The anti-virus module scans incoming mail when it is received, as well as when an attachment is opened.

The well-known domestic antivirus developer Kaspersky Lab also licenses the antivirus core of Kaspersky Antivirus for use by third-party software manufacturers.

In particular, the Kaspersky Anti-Virus kernel is integrated into the Antigen software package from Sybari Software. This complex provides full-scale protection of corporate mail gateways. Thanks to this, Kaspersky Lab's unique virus detection and neutralization technologies have become available to thousands of enterprises around the world that use Antigen.

As a result of an agreement reached between Kaspersky Lab (http://www.kaspersky.ru) and Ritlabs (http://www.ritlabs.com/ru), anti-virus filtering functions have been introduced for the above-mentioned email program The Bat! Thanks to collaboration with Kaspersky Anti-Virus, users of The Bat! are provided by automatic virus scanning of all incoming and outgoing mail immediately at the time of its delivery or sending.

Aladdin Knowledge Systems, one of the world leaders in the field of computer data protection, has integrated the Kaspersky Anti-Virus software core into its eSafe complex. Thus, Aladdin eSafe users receive additional benefits in the field of detecting and treating malware, based on the advanced developments of Kaspersky Lab.

The Kaspersky Anti-Virus kernel is also used in the antiviruses F-Secure (Finland), G-Data (Germany) and Vintage Solutions (Japan). Licensing agreements were concluded with Itamigo and Deerfield.com (UK).

Other examples include the antivirus kernel of the Israeli company CARMEL, which was sold to Microsoft, as well as the well-known antivirus utility MSAV, supplied as part of the MS-DOS operating system.

What's included in the package

DialogNauka CJSC sells the following components of its anti-virus technologies to third-party software developers:

  • Doctor Web anti-virus engine in the form of a dynamic link library DRWEB32.DLL with a set of anti-virus databases;
  • versions of Doctor Web for the Microsoft Windows operating system without a user interface (DrWeb32w and SpIDerGuard)

The anti-virus kernel can be used in any programs and systems. As for Doctor Web versions without a user interface, they are intended primarily for those who want to create their own anti-virus program.

The kit includes a detailed description of the software interface of the Doctor Web anti-virus core, the source code of a program that demonstrates how to work with this interface, as well as the source code of a simple anti-virus program DRW32EX.

If necessary, you can obtain the source texts of the program for loading and unloading the DRWEB32.DLL library, compiled in the C programming language. This program may be required if the anti-virus engine is intended to be used on a system that does not support the Win32 PE loadable module format (the Doctor Web anti-virus engine is capable of any IA-32 platform from Intel 386 and higher).

As for Kaspersky Lab, depending on the terms of the contract, either only a COM object that implements the functions of the anti-virus kernel, or a complete set of source codes with documentation and examples of their use, can be provided. Even regular training on new kernel functionality is possible.

Today, more than ever, anti-virus software is not only the most in demand in the security system of any operating system, but also one of its main components. And if previously the user had a very limited, modest choice, now you can find a lot of such programs. But if you look at the list of “Top 10 antiviruses”, you will notice that not all of them are equivalent in terms of functionality. Let's look at the most popular packages. At the same time, the analysis will include both paid and shareware (antivirus for 30 days), and freely distributed applications. But first things first.

Top 10 antiviruses for Windows: testing criteria

Before you start compiling a rating, you should probably familiarize yourself with the basic criteria that are used in most cases when testing such software.

Naturally, it is simply impossible to consider all known packages. However, among all those designed to ensure the protection of a computer system in the broadest sense, the most popular can be identified. At the same time, we will take into account both the official ratings of independent laboratories and reviews of users who use this or that software product in practice. In addition, mobile programs will not be affected; we will focus on stationary systems.

As for conducting basic tests, as a rule, they include several main aspects:

  • availability of paid and free versions and limitations related to functionality;
  • standard scanning speed;
  • quick identification of potential threats and the ability to remove or quarantine them using built-in algorithms;
  • frequency of updating anti-virus databases;
  • self-defense and reliability;
  • availability of additional features.

As can be seen from the list above, checking the operation of antivirus software allows you to determine the strengths and weaknesses of a particular product. Next, I will consider the most popular software packages included in the Top 10 antiviruses, and also give their main characteristics, of course, taking into account the opinions of people who use them in their daily work.

Kaspersky Lab software products

First, let's look at the software modules developed by Kaspersky Lab, which are extremely popular in the post-Soviet space.

It’s impossible to single out just one program here, because among them you can find the standard Kaspersky Antivirus scanner, modules like Internet Security, portable utilities like the Virus Removal Tool, and even boot disks for damaged Rescue Disc systems.

It is immediately worth noting two main disadvantages: firstly, judging by the reviews, almost all programs, with rare exceptions, are paid or shareware, and secondly, the system requirements are unreasonably high, which makes it impossible to use them in relatively weak configurations . Naturally, this scares off many ordinary users, although activation keys for Kaspersky Antivirus or Internet Security can easily be found on the World Wide Web.

On the other hand, the activation situation can be corrected in another way. For example, Kaspersky keys can be generated using special applications like Key Manager. True, this approach is, to put it mildly, illegal, however, as a way out, it is used by many users.

The speed of operation on modern machines is average (for some reason, more and more heavyweight versions are being created for new configurations), but constantly updated databases, the unique technology for identifying and removing known viruses and potentially dangerous programs are at their best. It is not surprising that Kapersky Laboratory is today a leader among security software developers.

And two more words about the recovery disk. It is unique in its own way, since it loads a scanner with a graphical interface even before Windows itself starts, allowing you to remove threats even from RAM.

The same applies to the portable utility Virus Removal Tool, which can track any threat on an infected terminal. It can only be compared with a similar utility from Dr. Web.

Protection from Dr. Web

Before us is another of the strongest representatives in the field of security - the famous “Doctor Web”, who stood at the origins of the creation of all anti-virus software since time immemorial.

Among the huge number of programs you can also find standard scanners, security tools for Internet surfing, portable utilities, and recovery disks. You can't list everything.

The main factors in favor of this developer’s software include high speed, instant detection of threats with the ability to either completely remove or isolate them, as well as a moderate load on the system as a whole. In general, from the point of view of most users, this is a kind of lightweight version of Kaspersky. There is still something interesting here. In particular, this is Dr. Web Katana. It is believed that this is a new generation software product. It is focused on the use of “sand” technologies, i.e. placing a threat in the “cloud” or “sandbox” (whatever you want to call it) for analysis before it penetrates the system. However, if you look at it, there is no particular innovation here, because this technique was used in the free Panda antivirus. In addition, according to many users, Dr. Web Katana is a kind of Security Space with the same technologies. However, generally speaking, any software from this developer is quite stable and powerful. It is not surprising that many users prefer such packages.

ESET programs

Speaking about the Top 10 antiviruses, it is impossible not to mention another bright representative of this field - the ESET company, which became famous for such a well-known product as NOD32. A little later, the ESET Smart Security module was born.

If we consider these programs, we can note an interesting point. To activate the full functionality of any package, you can do two things. On the one hand, this is the acquisition of an official license. On the other hand, you can install a trial antivirus for free, but activate it every 30 days. The situation with activation is also interesting.

As absolutely all users note, for ESET Smart Security (or for a standard antivirus) on the official website you could find freely distributed keys in the form of a login and password. Until recently, only this data could be used. Now the process has become somewhat more complicated: first you need to login and password on a special website, convert it into a license number, and only then enter it into the registration field in the program itself. However, if you do not pay attention to such trifles, you can note that this antivirus is one of the best. Pros noted by users:

  • virus signature databases are updated several times a day,
  • identification of threats at the highest level,
  • there are no conflicts with system components (firewall),
  • the package has the strongest self-defense,
  • there are no false alarms, etc.

Separately, it is worth noting that the load on the system is minimal, and the use of the Anti-Theft module even allows you to protect data from theft or misuse for personal gain.

AVG Antivirus

AVG Antivirus is paid software designed to provide comprehensive security for computer systems (there is also a free, truncated version). And although today this package is no longer among the top five, it nevertheless demonstrates fairly high speed and stability.

In principle, it is ideal for home use, because, in addition to speed, it has a convenient Russified interface and more or less stable behavior. True, as some users note, sometimes it is able to miss threats. And this does not apply to viruses as such, but rather to spyware or advertising “junk” called Malware and Adware. The program’s own module, although widely advertised, still, according to users, looks somewhat unfinished. And an additional firewall can often cause conflicts with the “native” Windows firewall if both modules are active.

Avira package

Avira is another member of the antivirus family. It is not fundamentally different from most similar packages. However, if you read user reviews about it, you can find quite interesting posts.

Many people do not recommend using the free version under any circumstances, since some modules are simply missing in it. To ensure reliable protection, you will have to purchase a paid product. But such an antivirus is suitable for versions 8 and 10, in which the system itself uses a lot of resources, and the package uses them at the lowest level. In principle, Avira is best suited for, say, budget laptops and weaker computers. A network installation, however, is out of the question.

Cloud service Panda Cloud

Free at one time became almost a revolution in the field of antivirus technologies. The use of a so-called “sandbox” to submit suspicious content for analysis before it penetrates the system has made this application especially popular among users of all levels.

And it is precisely with the “sandbox” that this antivirus is associated today. Yes, indeed, this technology, unlike other programs, allows you to prevent threats from entering the system. For example, any virus first saves its body on the hard drive or in RAM, and only then begins its activity. Here the matter does not come to conservation. First, the suspicious file is sent to a cloud service, where it is checked, and only then can it be saved in the system. True, according to eyewitnesses, unfortunately, this can take quite a lot of time and unnecessarily loads the system. On the other hand, it’s worth asking yourself what is more important: security or increased verification time? However, for modern computer configurations with Internet connection speeds of 100 Mbit/s and higher, it can be used without problems. By the way, its own protection is provided precisely through the “cloud”, which sometimes causes criticism.

Avast Pro Antivirus Scanner

Now a few words about another prominent representative. It is quite popular among many users, however, despite the presence of the same sandbox, anti-spyware, network scanner, firewall and virtual account, unfortunately, Avast Pro Antivirus is outperformed in terms of the main indicators of performance, functionality and reliability clearly loses to such giants as Kaspersky Lab software products or applications using Bitdefender technologies, although it demonstrates high scanning speed and low resource consumption.

Users are attracted to this product mainly by the fact that the free version of the package is as functional as possible and does not differ much from paid software. In addition, this antivirus works on all versions of Windows, including Windows 10, and works great even on outdated machines.

360 Security Packages

Before us is probably one of the fastest antiviruses of our time - 360 Security, developed by Chinese specialists. In general, all products labeled “360” are distinguished by enviable speed of operation (the same Internet browser 360 Safety Browser).

Despite its main purpose, the program has additional modules to eliminate operating system vulnerabilities and optimize it. But neither the speed of operation nor the free distribution can be compared with false alarms. In the list of programs that have the highest indicators for this criterion, this software occupies one of the first places. According to many experts, conflicts arise at the system level due to additional optimizers, the action of which intersects with the execution of tasks of the OS itself.

Software products based on Bitdefender technologies

Another “old man” among the most famous defenders of operating systems is Bitdefender. Unfortunately, in 2015 it lost the palm to Kaspersky Lab products, nevertheless, in antivirus fashion, so to speak, it is one of the trendsetters.

If you look a little more closely, you will notice that many modern programs (the same 360 ​​Security package) in different variations are made precisely on the basis of these technologies. Despite the rich functional base, it also has its shortcomings. Firstly, you will not find the Russian antivirus (Russified) Bitdefender, since it does not exist in nature at all. Secondly, despite the use of the latest technological developments in terms of system protection, unfortunately, it shows too high a number of false positives (by the way, according to experts, this is typical for the entire group of programs created on the basis of Bitdefender). The presence of additional optimizer components and their own firewalls generally does not affect the behavior of such antiviruses for the better. But you can’t deny the speed of this application. In addition, P2P is used for verification, but there is no real-time email verification, which many people do not like.

Antivirus from Microsoft

Another application that is notable for its enviable performance with or without reason is Microsoft's own product called Security Essentials.

This package is included in the Top 10 antiviruses, apparently, only because it is designed exclusively for Windows systems, which means it does not cause absolutely any conflicts at the system level. Besides, who else, if not specialists from Microsoft, knows all the security holes and vulnerabilities of their own operating systems. By the way, an interesting fact is that the initial builds of Windows 7 and Windows 8 had MSE as standard, but then for some reason this kit was abandoned. However, for Windows it can become the simplest solution in terms of security, although you can’t count on any special functionality.

McAfee app

As for this application, it looks quite interesting. However, it has gained the greatest popularity in the field of application on mobile devices with all kinds of blocking, however, on desktop computers this antivirus behaves no worse.

The program has low-level support for P2P networks when sharing Instant Messenger files, and also offers 2-level protection, in which the WormStopper and ScriptStopper modules play a major role. But in general, according to consumers, the functionality is at an average level, and the program itself is focused more on identifying spyware, computer worms and Trojans and preventing executable scripts or malicious code from entering the system.

Combined antiviruses and optimizers

Naturally, only those included in the Top 10 antiviruses were considered here. If we talk about other software of this kind, we can note some packages containing anti-virus modules in their sets.

What to prefer?

Naturally, all antiviruses have certain similarities and differences. What to install? Here you need to proceed from the needs and the level of protection provided. As a rule, corporate clients should purchase something more powerful with the possibility of network installation (Kaspersky, Dr. Web, ESET). As for home use, here the user chooses what he needs (if desired, you can even find an antivirus for a year - without registration or purchase). But, if you look at user reviews, it is better to install Panda Cloud, even despite some additional load on the system and the time it takes to check in the sandbox. But this is where there is a complete guarantee that the threat will not penetrate the system in any way. However, everyone is free to choose for themselves what exactly they need. If activation is not difficult, please: ESET products work fine on home systems. But using optimizers with anti-virus modules as the main means of protection is highly undesirable. Well, it’s also impossible to say which program takes first place: there are so many users, so many opinions.
