Check for viruses online kaspersky. Downloading and installing the scanner Kaspersky Virus Removal Tool

Proprietary utility from Kaspersky Lab Kaspersky AVP Tool Is a free scanner that quickly and efficiently detects Trojans, viruses, Internet worms and thousands of other threats. They are then either removed or moved to quarantine.

Kaspersky AVP Tool has a fairly simple appearance. Its installation on an infected computer takes place within a couple of minutes - even if we are talking about Windows Safe Mode. The search for malware is carried out using signature databases; there is its own heuristic analyzer.

The user interface has been significantly improved in the latest version of Kaspersky AVP Tool, which you can download from the website. The creators of the scanner have simplified the installer, configured launch from flash drives. The treatment of active infection has also been improved, as well as the self-defense of the process itself. Do not forget about the use of "cloud" technologies called Kaspersky Security Network.

Among the features of Kaspersky AVP Tool:

Completely free antivirus utility to quickly scan your computer.
The program has a simple appearance.
It allows you to collect information about the system, makes the creation of treatment scripts fully interactive.
Manual and automatic treatment of your PC from Trojans, viruses and worms.

Of course, the payback for the free scanner is that Kaspersky AVP Tool does not provide the user with real-time protection. It also does not include a module for automatic updating of virus databases. This utility will not replace your usual antivirus software. Therefore, we advise you to install a free antivirus, which you can download on this one, or purchase a paid one.

For a new PC check (for example, in a week or in a month), the user will need to download this utility again with the latest anti-virus databases. Kaspersky AVP Tool does not conflict with other anti-virus programs, so it can be used as an additional means of protection.

Services that allow you to check your computer for viruses online are conventionally divided into three types: system scanners, file scanners, and spyware and adware scanners.

System scanners scan the entire contents of a computer's disks or only selected areas for malware.
File scanners check for cleanliness individual files specified by the user.
Spyware / adware search tools are "sharpened" to identify threats of this type only.

The first and third types are not always clearly separated from each other. For example, antivirus scanners can detect both explicit malware and potentially unwanted programs (for example, displaying ads) that are not, in fact, viruses. And ad search tools are designed to respond to known viruses and Trojans.

Online services differ from traditional antiviruses in that they:

Do not always require installation on a computer. However, almost all system scanners and ad / spyware finders need to download a scan engine that works with cloud scanning technology. The loaded module transmits data about files from the client machine to the server and receives an answer from it, whether the files pose a threat.
They "weigh" a little, since they do not have their own virus databases.
Cannot start autonomously. Any online scanner needs the Internet to work.
They do not have algorithms for "curing" and deleting infected objects (with rare exceptions).
Does not have system security features.

- a simple, lightweight and fast online scanner that can check the system for active threats in a couple of minutes for free, as well as assess the state of computer protection - whether an antivirus program is installed, whether a firewall is enabled. Generates a security report after each check. With constant use, it can run on a schedule.

McAfee Security Scan Plus is a worthy addition to the comprehensive McAffee antivirus product that is already available for the money. It does not have the functions of removing malicious programs - it only informs about the detection of threats, and which ones, it does not always report.

Advantages:

High scanning speed without slowing down your computer.
System security assessment function.
Russian localization.

Disadvantages:

It is aimed at users of McAfeeTotal Protection antivirus, the rest is trying to persuade them to buy it.
Does not remove detected malware.
It does not always tell which object (file, website) is considered dangerous. Clicking on the "Fix Now" button redirects to the purchase page of the developer's main product.

- a more advanced solution in comparison with the McAfee scanner, as it is capable of not only detecting threats, but also removing them. Scans much slower but deeper. It is able to recognize all types of malicious and potentially dangerous objects - viruses, spyware and adware modules, worms, Trojans, licensed software hacking tools (keygens and "cracks"), etc. During the scan, it significantly loads system resources.

Panda Cloud Cleaner allows the user to choose the scan area himself - all disks or individual directories (however, the Windows folder, autorun areas and RAM are checked with any choice).

To "cure" an infected system, the program has the following:

Quarantine and file deletion function.
"Kill all process" is a tool for killing all processes (it makes it possible to unload active malware from memory if it cannot be done otherwise).
"Unlock files" - the function of unlocking files.
"Send files to Panda" - sending suspicious files for analysis to the Panda virus laboratory.

Advantages of Panda Cloud Cleaner:

Rich enough functionality for a free program.
Availability of "treatment" tools.
Lack of binding to the main product of the developer - Panda Internet Security.

Disadvantages:

Relatively low check speed.
Lack of Russian language

Is a free product of one of the world's most popular antivirus solutions developers - BitDefender SRL. Installed as a browser extension through which the download page was opened. Launched by pressing the "Scan now" button on the same page. According to the authors, it checks the computer for all types of active threats. There is no "cure" function.

The scanning process takes less than a minute. Judging by this, the utility checks only active processes in RAM and, possibly, malicious scripts in the context of the browser from which it was launched.

After verification, you will be unobtrusively offered to use Bitdefender Internet Security for free for 6 months.

Bitdefender QuickScan Pros:

Highest scanning speed.
No load on system resources.
Easy to install and remove.

Disadvantages:

Lack of Russian localization.
If it were not for the eminent developer, it would be unclear whether the service performs its tasks at all - scanning is so fast.

Emsisoft MalAware is another free cloud antivirus scanner that works without installing on a computer. Runs immediately after loading. Like most similar services, it only performs quick scans of startup areas and active processes. For a deeper check and "cure" (if necessary) offers to download another product Emsisoft AntiMalware, paid.

Emsisoft MalAware is slightly slower than Bitdefender QuickScan - about 3 minutes. There is a Russian language and a function for saving logs.

Utility advantages:

High performance.
Work without installation.
Simplicity.

Disadvantages:

Poor functionality.
The impression was that the program was created exclusively to promote the developer's paid products.

Is a free online service of "domestic style" developed by Kaspersky Lab and the well-known anti-virus portal Virusinfo.info. Works in tandem with Oleg Zaitsev's AVZ utility, which is used as a collector of suspicious files from a potentially infected computer. A zip archive with copies of the collected files (quarantine) is sent over the Internet for analysis to the CyberHelper computing system.

When uploading a quarantine to the service, the user can specify his email for a response - a link to the research result will be sent there. The same link will appear on the page that opens after downloading.

How to use the VirusDetector service:

Download, unzip and run the AVZ antivirus utility with administrator rights.
Open the menu "File" => "Standard scripts" and execute "Script for collecting files of express analysis of the PC" at number 8.

Upload quarantine to the server. It is located in the LOG folder, which is located in the same directory as AVZ.

Check your mailbox after 20-30 minutes. After about this time, the analysis will be completed and the results will be ready. They are displayed in a table with detailed information about each file. VirusDetector does not give advice on "treatment" - for it he suggests contacting resource consultants.

Strengths of VirusDetector:

Deep professional analysis of suspicious files.
Detailed information about each checked object.
No need to register for the service.

Disadvantages:

High complexity of use.

Checking files online

The operation of file scanning services without installing an antivirus is as follows: the user uploads a suspicious object to the site, where it is scanned by several dozen antivirus engines. Based on the result of the scan, you can make a conclusion about the danger or safety of the file.

- the most famous site for this purpose. Scans files up to 128 mb, downloaded both from a PC and from the Internet. Can scan entire web pages for infection. The final result of the check is summarized in a table. In addition to it, the site displays information about the reputation of the file and the data of its internal structure.

It can find information about previously scanned objects by checksum, URL or IP address.

Is another service that works without downloading. Scans files up to 20 mb in size and quarantine archives containing up to 20 objects. Has the same set of antivirus engines as Virustotal.

Jotti

Jotti uses half the anti-virus suite of the two previous services. Checks up to five files simultaneously if their size does not exceed 50 mb. It can find data of previously checked objects by hash sums.

- a service similar to the previous ones for checking the cleanliness of files. Differs in the fastest scanning speed.

The service is designed to search for malware among extensions, plugins, scripts and browser applications. It finds not only malicious code, but also vulnerabilities through which unwanted software is installed on the computer.

And now let's answer the most exciting question: can online scanners replace antivirus? No. They cannot provide comprehensive anti-virus protection, since they are "trained" only to detect, but not to repel malicious attacks.

Not all users install an antivirus on their computer or laptop. Some - laziness, others - do not see the need for this. And when suddenly the PC starts to behave strangely (it glitches and slows down or there is an advertisement in the browser), then you can simply check the computer for viruses online and for free. Fortunately, there are plenty of options today.

Below are the 7 best antiviruses that can scan for viruses online. True, you won't be able to check your computer without downloading the installer. Virus scanning is performed online, but antivirus needs access to your files. Therefore, some of them are installed as a plug-in for the browser, and some as a small utility. Also on the list there are 2 antiviruses that support online virus scanning without downloading. Which one to use is up to you.

Kaspersky will help you quickly scan your computer for viruses online. A full-fledged antivirus is well known in Russia, and its "little brother" is also popular.

The program works in the "cloud", so you can quickly scan any PC or laptop for viruses online.

Its main advantages:

does not slow down Windows (which cannot be said about the full-fledged antivirus Kaspersky, which consumes a lot of resources during the scan);
does not conflict with other antiviruses installed on the computer;
does not delete found viruses, but only reports them (on the one hand, this is a plus, but on the other, you will have to delete them manually);
produces a detailed report.

Online virus scanning in Kaspersky is very simple:

Download the installer from this link.
Run the program.
Wait for the end of the check.

After that, you will only have to remove the viruses (if they were found).

BitDefender QuickScan - Fast online PC virus scan

Another way to clean your computer from viruses online is by using BitDefender QuickScan. It is considered to be very effective and has great success overseas. Approximately like our Kaspersky.

Cleaning your computer from viruses online is also easy. You just need:

Follow this link.
Click on "Scan Now".
Install a browser plug-in through which the antivirus will gain access to your folders and files.
Wait until the end of the check.

The main advantage of BitDefender is its fast online virus scan. On average, it takes 1-2 minutes. On the one hand, this is cool, but on the other, what can he scan in such a short time?

Most likely, the online scanner checks the main list of the most common threats: system files, startup - i.e. those places where viruses mostly "live". The developers themselves say that checking the computer for viruses online is carried out in the cloud mode (on their servers), which is why it is performed so quickly.

ESET Online Scanner - efficiently scan your computer for viruses

The next way to check your laptop for viruses online is using a free ESET product from the developers of NOD32. To start checking, follow this link.

It is recommended to scan your PC via Internet Explorer - in this case, the scan will be performed in a browser window. When using Chrome, Firefox or Opera, the user will have to download a small file, and the analysis of the PC will be performed in a separate program.

After downloading and running the file, you need to set the settings. For example, enable scanning of archives and potentially dangerous programs. You can also remove the checkbox in the "Delete threats" item so that the antivirus does not accidentally erase important files that, in its opinion, are infected. Then click the "Get Started" button.

ESET Online Scaner will update the databases, after which an online scan of your PC for viruses will begin.

a thorough system scan (on average it takes 40 minutes - depending on your internet speed and the size of your HDD);
detects any threats;
knows how to find malware, incl. in the registry;
performs heuristic analysis;
generates a complete report on the work performed.

Another plus is that the online scanner is automatically deleted after the end of the scan. That is, there will be no files left after it.

Thus, ESET Antivirus is perhaps the best way to clean your computer from viruses online. Its only drawback is the need for installation.

Panda Cloud Cleaner - online flash drive virus scan

The users are offered 4 versions to choose from:

standard;
portable (does not require installation);
for scanning a USB flash drive;
in ISO format (rescue boot disk for PC virus scan that won't turn on).

Which version to choose, decide for yourself. For example, if you want to check a USB flash drive for viruses online, then download the third installer on the developer's website.

Main advantages:

quick check (on average - 20-30 minutes);
detection of common threats;
effective online virus cleaning.

As in the previous case, the Panda also "self-destructs" after a successful check and treatment of viruses. That is, it is automatically deleted and does not leave behind files.

F-Secure Online Scanner - virus and spyware treatment

Another excellent antivirus that can scan your computer for viruses online. To start testing, go to the developers site and click on the "Run" button. After downloading and running the installer, a new window will open in which scanning of the laptop or PC will begin.

The main advantages of this antivirus:

fast scanning - on average it takes 10-15 minutes;
effective treatment of viruses and spyware utilities;
works even with antivirus installed on your PC.

Before starting the test, it is advisable to turn off "heavy" programs. This will help speed up the scanning process.

VirusTotal - online virus scan without download

All previous options had one common drawback - the need to download the installer. In this case, you can scan your computer for viruses online without installing any programs.

VirusTotal is a service from Google that can check any files on your PC. It can also scan websites for malicious utilities. The service is very easy to use:

Follow this link.
Specify the path to the file you want to crawl or the URL of any site.
Click the Check button.

Wait for the check to be performed, and then see the report.

You will not be able to check all documents on your computer through VirusTotal. He can scan sites and files separately. This option is suitable for those who, for example, downloaded a program and want to make sure that it is free of viruses before installing. For such cases, VirusTotal is best suited, because it does not need to be downloaded.

Dr.Web - effective file scanning for viruses

And the last way to check your computer for viruses online is through Doctor Web. He has a great service with which you can check individual files. For this:

Go to this site.
Click Browse and specify the path to the file you want to scan.
Click the "Check!" Button.

In this case, you can scan your computer for viruses online without installing Dr. Web. But, like VirusTotal, Doctor Web can scan only one file at a time.

A few words in conclusion

It sounds strange, but you cannot completely scan a laptop or computer and remove viruses online. The first 5 antiviruses require a small file to be installed. The question arises: isn't it easier to install the full version of the same Kaspersky or BitDefender? They have more features, plus they provide real-time protection for your PC. In addition, many popular antiviruses have free versions.

The last 2 options are VirusTotal and Dr. Web - do not require installation, but check one file at a time. This is also not very convenient.

By the way, a computer or laptop can be infected not by viruses, but by malware. As a result, ads appear in the browser, third-party pages of unknown sites open, etc. In this case, antiviruses will not help; special software is required here.

Actually, that's all. Above, 7 ways were considered how you can check your computer or laptop for viruses online for free. Which antivirus to use is up to you. If you want to completely check your computer for viruses, then choose one of the first 5 programs. And if you need to scan several files, then use the services VirusTotal or Dr. Web.

If the antivirus installed on your computer does not detect anything suspicious, but symptoms are evident (freezes, incomprehensible running processes, autorun.inf appearing on flash drives, etc.), a "one-time antivirus" is required. It's easy to handle it - just download from the link and run. In this case, during the scan, it is advisable to disable the antivirus, which is installed on a permanent basis.

Advantages of disposable antiviruses

1. Free. For home use, almost all disposable antiviruses are free.

disadvantages

1. They are not able to protect your computer all the time (there is no module for real-time protection) and there is no update of the anti-virus databases.

2. You have to download it again every time so that such an antivirus detects new viruses.

Dr.Web CureIt!

Dr.Web CureIt! is a good disposable antivirus. Knows how to deal with running viruses (does not allow himself to be killed during scanning).

HerdProtect

An online antivirus that scans all computer files with 68 antivirus databases. How to use it, I told in a separate article.

This is a good option if you have unlimited internet.

Minus: cannot disinfect infected files.

A plus: you do not need to download again to check, the databases are always fresh.

Kaspersky Virus Removal Tool

ESET Online Scanner

Plus the Online Scanner - no need to worry about downloading new versions with fresh databases. Just open the link or run esetsmartinstaller_rus.exe, the antivirus will start, update and check your computer for viruses.

Norton Security Scan

Norton Security Scan is another one-time anti-virus. You can download the interface in English, but simple.

Checks hard drives very quickly. Requires a connected internet like Eset Online Scanner.

On first launch, it creates a shortcut to itself, which is strange.

In general, it is better not to use it, since viruses widespread in Russia get into its database a little late. The newest vinlockers (ransomware banners) are unlikely to be found.

AVZ or Zaitsev Anti-Virus

Powerful anti-virus utility (not a full-fledged antivirus!) for advanced users. The functions are not the sea, but the whole ocean.

Supports updating of anti-virus databases from the Internet. Unlike disposable antiviruses, it cannot disinfect infected * .exe files. It is more of an anti-spyware with many unique additional features. I will quote the words of the author AVZ: “ The utility is a direct analogue of Trojan Hunter and LavaSoft Ad-aware 6. The primary task of the program is to remove AdWare, SpyWare and Trojans."In the archive with the program there is help for all functions, it must be carefully read before the first launch.

Some viruses can harm not only your computer, but also the antivirus that is installed on this computer. From the influence of viruses, the normal operation of the antivirus stops, as a result of which your computer is at risk. In order to neutralize viruses, the Kaspersky Lab company has released a special utility called Kaspersky Virus Removal Tool.

In addition, with the help of Kaspersky's free curing utility, you can perform a comprehensive system scan for viruses and malware. If necessary, the utility will quickly eliminate the detected viruses.

I want to familiarize you with this utility by talking about the pros and cons of the program, after which you can decide to download it using the link at the end of the article.

Pros of Kaspersky Virus Removal Tool:

1. The program is available for download absolutely free of charge and has no internal purchases.

2. Nice and intuitive interface. For some reason, the developers of some healing utilities do not pay due attention to such an important component as a well-thought-out program interface. Kaspersky Lab has taken care of this aspect, so you will not have any difficulties when launching the utility for the first time.

3. The program does not conflict with antiviruses and other third-party antivirus programs, so you do not have to uninstall them in order to use Kaspersky's utility normally. This means that the program does not matter at all whether you use Kaspersky Anti-Virus or any other vendor's antivirus.

4. The utility is able to find and eliminate viruses that are not included in the signature database. While many antiviruses search for viruses based on the available anti-virus database, the Kaspersky utility uses a different algorithm that is able to find not only those viruses that have been included in its database, but also unknown viruses.

5. The utility is able to "cure" infected files. Now you do not have to delete the infected program - the Kaspersky utility will find the virus code in it and remove it.

6. If the virus that infected your computer blocks the installation of the antivirus utility, then you can install it completely safely using Windows Safe Mode.

7. After collecting all the necessary information, the program will create special scripts that you can later use for manual treatment.

This is where the advantages of the utility end, so I move on to the disadvantages.

Cons of Kaspersky Virus Removal Tool.

1. The curing utility is by no means an antivirus that can provide full protection for your computer in real time. This product should only be used as an add-on to your existing antivirus software.

2. This utility does not know how to independently update its databases. Therefore, for subsequent system checks to be effective, you will have to periodically visit the official Kaspersky Lab website to download and install the latest updates yourself. Please note that the fourth plus of the utility, which I gave above, does not in any way free you from updating the program.

3. Lack of help and additional services. Kaspersky Lab has deprived this product of any service support. Therefore, if you have any problems while working with the utility, you will have to contact thematic forums.

Despite its shortcomings, Kaspersky Virus Removal Tool is a worthwhile product that will perfectly complement your existing antivirus and can significantly increase the protection of your computer.
