Check your netbook for viruses online. Norton Power Eraser - identifying virus threats

Checking your computer online for viruses is not as simple as it seems. First, let's note the fact that it is impossible to completely scan your hard drive for viruses. Most online services require you to upload a certain file, archive or folder to the site and only then check it. Only some perform a full PC scan. It's also worth noting that if your antivirus is up to date and working reliably, but the system is behaving strangely, you may need to remove a potentially unwanted program that is not a virus. Accordingly, such a program is not detected by a regular defender, and an online antivirus will not see it at all. However, if you need to perform an online scan of your PC and individual files, we offer a review of the best online antiviruses.

Review of free online antiviruses

We put ESET Online Scanner in first place in terms of scanning quality and speed, where you can scan not just individual files, but the entire PC, for free, but only once. To do this, perform the following steps:

Follow the link and click the “Run” button.

A small exe file will download. We save it to the desktop so that we can quickly delete it later. Then we start scanning.

We accept the terms of the license agreement.

Check the “Enable detection of potentially unwanted applications” checkbox. Click “Scan”.

After loading the databases and other components, this program will scan your PC.

It is worth noting that if you have an updated ESET antivirus installed, then you will already be provided with high-quality protection even from unwanted programs.

In second place is the Dr.Web antivirus and its online analogue. To verify files using it, perform the following steps:

Follow the link to the resource website. Upload the file by clicking on the “Browse” button and then clicking “Check”.

The program will scan the file and create an archive with the scan results.

BitDefender antivirus also has online scanning. To run a scan in real mode, perform the following steps:

Follow the link and click “Scan now”.

An extension will be added to the browser that will gain access to files on your PC. Only after this will scanning for viruses begin.

The online service from the developers of the Panda antivirus also broke into the top five. Online ActiveScan scans your system and files in the cloud.

To check if there are viruses on your PC, follow these steps:

Follow the link and click “Scan”. The Internet Explorer browser will open, as a special extension will be added to it. Click on it and start scanning.

The result will be displayed in the same window.

You can also scan using McAfee antivirus for free, without registering or installing extensions. The Security Scan Plus resource works as follows:

Follow the link and click “Run”. A small window will open. Click “Scan” and wait for the results.

The report will be displayed in the same window.

There are many other online antiviruses on the Internet that can also be used to scan files. However, we recommend that you regularly update your antivirus and not install applications from unverified developers.

By visiting such a site from a computer, you will be taken to a harmless Internet resource, but by accessing it from a smartphone, you will secretly redirected to a site with an unpleasant “surprise”.

Send a suspicious file

Free antivirus software is very popular, but even these versions of the programs offer the ability to scan your entire computer. The most popular versions of antivirus software are: Avast FreeAntivirus, Kaspersky, NOD 32, Dr.Web. All of them have a full computer scan function. If the user runs a similar function using the appropriate program, it will scan all hard drives, files and folders stored on them for the presence of any malicious software. As you might guess, such a scanning procedure carries out a detailed check of the entire system, and accordingly, such a check will take much more time.

What programs can I use to scan my computer?

Each of the antivirus software presented above has its own advantages and disadvantages. For example, Kaspersky is the most famous antivirus for many and perhaps people believe that it is the most effective. On the one hand, such a statement is true, but on the other, it is not. The thing is that this antivirus loads the user’s system very heavily and, naturally, this does not have the best effect on the performance of the personal computer. At the same time, Kaspersky Anti-Virus provides good protection, since it has a built-in firewall, its own firewall, and the function of fully scanning the computer for malware.

Avast FreeAntivirus and NOD 32 are chosen by most personal computer users. This is primarily due to the fact that, unlike the previous option, these antiviruses are not so demanding on system resources and hardly load the PC. We can talk about them together, since they are very similar. As for functionality, they also have their own, quite good firewall, firewall, regularly updated database and many other advantages, including a full computer scan function. The disadvantages include the fact that often these antiviruses either miss viruses or identify some programs as malicious, which in fact are not.

As for the antivirus Dr. Web, today it is used much less frequently than before. In principle, this antivirus is also not bad and has everything necessary to protect and scan user activity on the network and search for various malicious applications on the computer. It is worth noting that this antivirus has an Internet service that allows you to scan your computer, which means that it is not necessary to buy and install this antivirus software.

Greetings, dear blog visitors. Dmitry Smirnov is in touch with you as always, and in this article I want to tell you about how to check your computer for viruses quickly and freely, simply and affordably! In the last article I wrote about that, and now I’ll tell you about viruses!

How to check your computer for viruses

Using your favorite computer, after a certain period of time, you began to notice that the boot process began to occur more slowly, programs open and run with greater delay, or some of them stopped functioning, produce errors, and sometimes it seems that the system itself produces some - visible actions not ordered by the user.

It's time to check your computer for viruses online. And what exactly will we check for? There may be several main options:

Checking your machine's system disks;
Checking system files for viruses and malware;
Checking for the presence of unnecessary and unused files, programs, the contents of Internet browser folders, temporary file storage folders, etc.;
Checking the compatibility of some programs to work together.

This list, of course, is not exhaustive, but it lists, perhaps, all the main types of system checks available to the average user. We will not take into account users at the level of professional programmers, hackers, etc.

When we think about verification, we assume that we need special, complex and expensive programs to carry out this process. Agree, I don’t really want to spend time searching and money buying all sorts of incomprehensible software, if it’s not at all clear what to check. I would like to note that an important feature of paid licensed software is the possibility of its regular updating, all possible support from the developers and the uninterrupted operation of its work and the presence of a large arsenal of various “fine settings”.

Free software cannot always boast of this, but there are quite worthy examples among it. Let's consider them.

A simple standard program contained in all the latest versions of the Microsoft Windows environment will help you check your system drives for free.
- Click Start, select Computer, a window appears indicating the drives. Place the cursor over the desired disk and press the right mouse button once. In the menu that opens, find properties and click.

In the same window, on the General tab, you can set disk cleanup and select categories of files that can be deleted as a result of the program. Do this with caution.

On the service tab, find the Run check button and click it.

By clicking Start, we force the system to start checking the selected disk. As a result of such a check, all system errors will be corrected and damaged disk sectors will be checked and restored (if you check both boxes). The system may ask you to start scanning the next time you boot. This may take a few minutes, depending on the size and condition of your drive. This repair program can be scheduled to run on all drives in the system at once. Then when loading they will be checked in order of priority.

There are a lot of well-known and well-proven free versions of anti-virus programs and healing utilities that will analyze the system or specified individual parts of it for the presence of viruses, Trojans, worms and other “pests” of the system. Here are some of these programs.
- Avast Free antivirus solution, which is successfully used by about 230 million people on Earth. You can download the program for free from the Russian-language website https://www.avast.ru/index. Of course, there are paid advanced packages of this antivirus, but we will talk about its free version.

The developers will ask you to go through simple procedures.

The program allows you to scan with a choice of parameters (viruses, outdated software, network threats, allows you to analyze system performance and suggest ways to optimize it. Of course, Avast Free will not save you from cutting-edge and complex viruses and malicious code, but for the average Internet user it is quite will suit you and you will like the ease of downloading, the interface, good and high-quality work.

For example, intelligent scanning has been launched.

And here are the results of this scan. You can eliminate everything in one fell swoop by clicking on the appropriate button.

2.6. Another excellent option for checking your system for viruses and malware is the free healing utility from Dr. Web – Cureit, available at http://free.drweb.ru/cureit.

2.7 Download this program, install and configure. It checks user-selected folders and drives for the presence of harmful “inhabitants” of the Internet. She will suggest actions with them (Quarantine-Cure-Delete). The distribution of the program increases with each release and is already about 200 MB.

A feature of versions released in the last 2-3 years is that the program does not block the operation of the system during testing and allows you to download other applications and programs.

3.1. The Total Commander program will allow you to check for the presence of unnecessary and unused files, programs, the contents of Internet browser folders, temporary file storage folders, etc.;

This solution allows you to:

Edit the list of startup programs;
Remove installed programs;
Clean the program registry;
Clean system disks;
Clean shortcuts that have not been launched by the user for a long time.

3.2. For example, let's run Registry Cleaner.

There are other similar packages of treatment and testing utilities that allow you to “clean” the system, delete unnecessary and faulty files, “fine-tune the system,” etc. (eg Ace Utilities, Norton Utilities). But you need to use them with great caution, understanding exactly what you are going to delete and how this may affect the operation of the system.

There is a class of programs that allow you to understand the compatibility of various software installed on your computer. Here we will not consider such programs due to their complexity and the ambiguity of their results.

You can limit yourself to only a few rules so that your system does not become inoperable after installing the next program:

If possible, do not install many programs of the same type of work on the disk (many cleaning programs, etc.);
Do not install several antiviruses together on the disks of one machine (they most often perceive each other as macro viruses and can block the operation of the system. Then you will need to start in safe mode and remove one of them;
Do not install unverified, dubious programs.

Study the computer and its components, informatization is the future. It is the key to success in many industries. And now you know how to check your computer for viruses free and easy!

Greetings to all readers of the blog site. Have you ever had situations where your computer does not work as usual? It takes a long time to load and programs open slowly. The solution to the problem can be to scan your computer online for viruses without installing additional extensions. Let's consider the most popular methods that may be useful to you.

Why check

Have you ever had situations where the antivirus does not find threats, but the laptop suddenly starts working slowly and messages of dubious content appear? By the way, in one of my recent posts I wrote, .

This behavior is associated with the appearance of a program with malicious code on the system. The installed antivirus does not find it and cannot remove it from the computer because it is a program. This is where special services can help. Use them, especially if you notice that your computer is not working properly.

But before working with them, pay attention to the following:

During operation, an additional module or extension is loaded, which communicates with the anti-virus database using the cloud;
Do not use unknown services; in one of my previous articles I wrote about that. If in doubt, check for advertisements. Manufacturers of high-quality software make money by selling products, so they will not place “dubious” advertising.

Important! You cannot protect your computer without antivirus software that has access to all files on the HDD.

How to scan in Dr.Web

This is an effective way. Let's look at why. This is the first antivirus created in Russia to offer this type of scanning. In addition, he offers:

By following the link online.drweb.com check the url - address, or file. To do this, you do not need to load any additional modules onto the HDD. Add the document you want to check in a special form.

After downloading it, click on the “check” button.

Important! To ensure the security of your information in real time, purchase full-fledged Doctor web . The method described above is used only for one-time diagnostics.

How to check in ESET

This is a free tool to effectively remove malicious code. Located at: esetnod32.ru . He can:

scan documents without installation;
detects all types of threats;
remove malicious code from the registry.

If you use Explorer, there is no need to download and install additional programs. For other browsers, download and run the application with the “exe” extension that the system offers. After loading the scanner, click on the “launch” button.

How Kaspersky online scanner works

This free utility is available at kaspersky.ru . It can identify common threats. The work takes place using cloud technology. This will reduce the time required for scanning. Also, Kaspersky developers took care of users working on Mac. It was released for them.

Important! The scanner works correctly with antiviruses installed on the system. It does not remove the code, but only reports it. After checking, you will have to delete everything yourself.

Working with the Virustotal service

It belongs to Google. Checks files for malicious software. To start working with it, go to the address virustotal.com . A form will open where we indicate a link to the blog, or select the necessary files on the HDD. Next, click on the “check” button.

Important! Anti-virus databases are regularly updated automatically, so Virustotal will find all the latest modifications of viruses.

Conclusion
