Anti-virus scanners are designed to scan your computer for malicious software and eliminate detected threats. Antivirus application is a scanner, checks the system at any time, does not provide permanent protection computer.

This shows the difference between anti-virus scanners and monitors (anti-viruses). An anti-virus scanner conducts one-time scans on demand, and an anti-virus installed on a computer constantly protects the PC.

Why do we need antivirus programs - scanners? Antivirus scanners for Windows are necessary to scan your computer in cases where permanently installed antiviruses cannot cope with their work. For example, the system began to slow down greatly without visible reasons, malfunctions began to appear in the operation of some programs, etc.

It is possible that malware has entered your computer. Therefore, it makes sense to check and, if something is found, cure the computer and eliminate the problems that have arisen.

Some users do not use antivirus applications on their computers. In such cases, you should check the system from time to time using an anti-virus scanner for prevention.

Some scanners are used in their work cloud servers, with whom they interact while checking the computer. Therefore, for this type of program to work, an Internet connection is required.

Other antivirus scanners are completely autonomous; they include all the latest antivirus databases at the time of downloading the application. For new check you should download the latest version of the antivirus scanner.

In this article we will look at free antivirus scanners (alas, there are also paid programs of this type) that work without installation on the computer. Such applications have some advantages, since there are situations when, as a result of a severe infection of the system, it becomes impossible installation antivirus program on computer. The portable, portable version of the anti-virus scanner will allow you to run the program not only from a computer disk, but also from removable media, for example, from a USB flash drive.

To scan for viruses, you should use a scanner from another manufacturer, different from the developer of the antivirus installed on the PC.

This manual presents the best antivirus scanners that support the Russian language and work in the operating room Windows system.

Conclusions of the article

The article discusses the best antivirus scanners that do not require installation on your computer. Programs can be launched from any convenient location on the computer, including from removable media. Anti-virus scanners are launched by the user independently for a one-time scan of the computer. Applications scan the system and remove viruses and malware from the computer.

If a lot of unnecessary advertising materials appear in the browser, files disappear somewhere on the desktop, or other incomprehensible things happen, and the antivirus is powerless against them, a virus removal utility comes to the rescue.

This concept means small program, which simply finds and removes viruses and their remnants.

This is an inferior antivirus, such as Doctor Web or Kaspersky, but a small part of them that only scans the system and removes all malware.

Such utilities do not require installation and, most often, are distributed completely free of charge.

Some antivirus giants release such utilities so that users can fully appreciate the power of their software.

An example of such is the same Doctor Web and Kaspersky.

The first “giant” has such a utility called Dr.Web CureIt, and the second one – Kaspersky Virus Removal Tool.

These two programs are the most popular of their kind, but far from the most effective. But they are distributed for free!

Using their example, we can consider the main functions and features of viruses removal utilities.

And then we’ll move on to considering those programs that really work effectively against ad viruses and others unnecessary programs.

• Several ways: How to clean your computer from viruses absolutely free

No. 6. Dr.Web CureIt

So, Dr.Web CureIt does not require installation.

It's very easy to use.

It all comes down to these few steps:

1. Launch the downloaded file.
2. Click on one big button “Start checking” (Figure 1.a).
3. In the next window, check off the threats that the program will look for on your computer (highlighted in green in Figure 1.b).
4. Click the big “Start scan” button.

After that, you just have to wait for the end of the check. This process is shown in Figure 2.a.

Upon completion, the user will see a report that displays detected viruses and the files that contain them.

An example of such a report is shown in Figure 2.b. Using the buttons at the bottom of the window, they can be deleted or quarantined.

That's the whole process of using Dr.Web CureIt.

No. 5. Kaspersky Virus Removal Tool

The use of Kaspersky Virus Removal Tool is very similar to what we saw in Dr.Web CureIt. In principle, the same applies to all other utilities for treating a computer.

As for the utility from Kaspersky, I want to believe that it is really powerful and that it is capable of efficiently finding all viruses.

But, judging by the reviews on the Internet, everything is not as rosy as it seems at first glance.

Moreover, it seems that the developers of Kaspersky Virus Removal Tool decided not to put too much effort into their product.

This is confirmed by the fact that latest version this program was released in September 2015.

Since that time, Kaspersky Lab specialists have not worked with the utility. This is evidenced by the official website of the program - www.kaspersky.ru/antivirus-removal-tool.

There, by the way, you can download this very utility.

On the forums you can find reviews that Kaspersky Virus Removal Tool does not find most ad viruses, which Dr.Web CureIt easily copes with.

Some write that it takes a very long time to run and heavily loads the computer's memory.

Often it is simply impossible to run other programs in parallel with Kaspersky Virus Removal Tool. Although, all Kaspersky products suffer from this.

In any case, although Kaspersky Virus Removal Tool is the brainchild of one of the best antivirus products of our time, it does not have even a quarter of the power that Kaspersky antiviruses are famous for.

Therefore, it is better to use one of the utilities listed below.

No. 4. AdwCleaner

In any topic on the forums where we're talking about about free utilities for removing viruses, AdwCleaner will appear.

And this is not at all surprising, because many people choose this particular program as an alternative to the popular Kaspersky Virus Removal Tool and Dr.Web CureIt.

Although, if you take all the many reviews and posts, then it can hardly be considered the most powerful of its kind. But AdwCleaner was created, as they say, with soul and for people.

After the standard and identical virus removal process for everyone, AdwCleaner shows recommendations on how to avoid similar problems further.

As for use, this healing utility is practically no different from the above-mentioned ones similar programs.

The AdwCleaner window is shown in Figure 4. All actions are concentrated in the section with the appropriate name (highlighted in the figure).

To start using it, you need to click the “Scan” button, and then wait until the end of the scan.

The “Results” section (located immediately below the “Actions” section) will contain the inspection report.

There you can select all the threats found or some specific ones and click the “Delete” button.

Of course, the scanning and removal algorithms for all such programs are different, but the method of use is almost the same for all.

As for AdwCleaner, judging by the reviews of people that they left on forums and in in social networks, this healing utility works better than Kaspersky and Doctor Web products.

There were cases when the same Kaspersky Virus Removal Tool did not find anything, but AdwCleaner found several dozen viruses and easily removed them from the computer.

No. 3. Anti-Malware

Anti-Malware is one of the most popular healing utilities.

Almost the same thing can be said about it as about AdwCleaner - in any topic about utilities for removing viruses, at least someone will write about Anti-Malware.

The peculiarity of this program is that it is a complete software with several tabs in the main window, extensive customization options, several scanning modes and a great variety of functions.

Thus, the user can set exceptions for scanning, set scheduled scans, restrict access to the utility for other users, and do much more.

He also has the opportunity to view history.

In general, Anti-Malware is much more than AdwCleaner, Kaspersky Virus Removal Tool and Dr.Web CureIt combined.

Moreover, this program is distributed completely free of charge.

It only has a Premium mode, in which a quick scan is available, the aforementioned scheduler, even real-time protection (!) and many others additional functions.

But the main Anti-Malware package is quite enough to detect and permanently remove certain viruses.

In some cases, users use it as a replacement for an antivirus, only checking it from time to time. Although doing so is highly not recommended.

Anti-Malware also has disadvantages. But they are very small.

For example, the utility detected Webalta and Conduit for one user, but did not respond to Mobogenie, which is also a completely adware program.

So in the race for the title of “best virus removal utility,” Anti-Malware clearly cannot claim first place. But her place in the top three is guaranteed!

Important: Anti-Malware has a full Russian language. Only for this you need to download it from the official website - ru.malwarebytes.org/mwb-download.

No. 2. Spybot Search & Destroy

This program differs from the others in having a very interesting interface - it is clear that few people worked on the program, and they did not spend a lot of time on beautiful design and advertising of their product.

But they spent a lot of time making a truly powerful virus removal tool for any modern computer.

The program interface is shown in Figure 6.

As you can see, in the main program window there are such standard items as system scan, quarantine and update.

Although there are two scans here - one for the system as a whole, the other for individual files.

This is very unusual for such programs.

There is a “Statistics” button, by clicking on which you can see how many viruses were on the computer for the entire time until Spybot Search& Destroy is on the computer, which of them have been deleted, and so on.

This is also very useful feature, which allows you to analyze the main ways threats reach your computer.

But the palm among non-standard functions goes to “Immunization”. It allows you to protect certain files from infection. A very unusual, but very useful feature!

Among the advanced tools there is a report creator, which makes it possible to create a report on the operation of the program and the state of the system.

There are also settings and another interesting item - “Startup tools”.

It allows you to specify those programs and functions that will be loaded with the system. For example, you can set automatic scanning at startup.

Most importantly, Spybot Search & Destroy protects against viruses very well - search is at the highest level, and removal occurs without side effects. And this is the main thing for such programs.

Important! Spybot Search & Destroy does not take first place in our rating today for one simple reason - it is unfinished!

For one user, this utility for some reason removed the drivers from the scanner; for another, the computer rebooted.

In addition, the creators with not very appropriate in this case They approached the licensing agreement with humor.

If they take their creation more seriously in the future, Spybot Search & Destroy may well outperform other similar programs.

Not all users install an antivirus on their computer or laptop. Some people are lazy, others don’t see the need for it. And when suddenly your PC starts behaving strangely (it’s buggy and slow, or advertising appears in the browser), you can simply check your computer for viruses online and for free. Fortunately, there are plenty of options today.

Below are 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 done online, but antiviruses need access to your files. Therefore, some of them are installed as a browser module, and some are installed as a small utility.

2. Click on “Scan Now”.
3. Install a browser module through which the antivirus will gain access to your folders and files.
4. Wait until the check is completed.

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

Most likely, the online scanner checks the main list of the most common threats: system files, autoloading – i.e. those places where viruses mainly “live”. The developers themselves say that checking your computer for viruses online is carried out in the cloud (on their servers), which is why it is done so quickly.

ESET Online Scanner - effectively scan your computer for viruses

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

It is recommended to scan your PC using Internet Explorer– in this case, the check will be performed in a browser window. When using Chrome, Firefox or Opera, the user will have to download a small file, and the PC analysis 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 clear the checkbox in the “Remove threats” item so that the antivirus does not accidentally erase important files, which, in his opinion, are infected. Then click the "Start" button.

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

• a thorough system scan (takes 40 minutes on average - depends on your Internet speed and HDD capacity);
• detects any threats;
• can detect malware, incl. in the register;

Panda Cloud Cleaner - online scanning of flash drives for viruses

Users are offered 4 versions to choose from:

• standard;
• portable (does not require installation);
• for scanning USB flash drive;
• V ISO format(emergency boot disk to check for viruses on a PC that won’t turn on).

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

Main advantages:

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

As in the previous case, Panda also “self-destructs” after successfully checking and treating viruses. That is, it is automatically deleted and does not leave any files behind.

F-Secure Online Scanner – treatment of viruses and spyware

Another excellent antivirus that can scan your computer for viruses online. To start checking, go to the developers’ website and click on the “Launch” button. After downloading and launching the installer, a new window will open in which scanning of the laptop or PC will begin.

The main advantages of this antivirus:

3. Click the “Check!” button.

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

A few words in conclusion

This sounds strange, but it is impossible to completely scan a laptop or computer and remove viruses online. The first 5 antiviruses require the installation of a small file. The question arises: isn’t it easier to install a full-fledged version of Kaspersky or BitDefender? They have more features, plus they provide real-time PC protection. 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 entirely convenient.

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

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

Cloud antivirus scanners are useful tools for additional analysis suspicious files, and users do not need to install the program to conduct the scan.

Online scanners have been tested

When selecting test participants, the finalists of the Digital Citizen Awards 2016 were primarily used. The researchers checked whether the vendor offered online tool scanning. Unfortunately, not all companies offer such opportunities, and not all tools are of high quality.

As a result, the following products and services took part in testing: , and .

It quickly became clear that not all products are classic online scanners that run in a browser. Many antivirus vendors now offer standalone utilities that you download and install on your computer. They can work together with the main anti-virus protection without conflicts or performance problems. They can only be used when it is necessary to further check the security status of the system.

Important note: This test does not include full-fledged antivirus products. The trial involves free tools that can be used to scan and evaluate system security. These programs are not intended to replace basic security solutions, in particular antiviruses, firewalls, and anti-spyware tools. They should be used to complement antivirus protection and help identify potential system problems that may be caused by malware.

How was the testing procedure?

First, the concept and architecture of the product were clarified - whether it was a classic online scanner, a standalone application, or a hybrid version of the two approaches. Before installing or launching the product under test, the test system was infected with malicious objects. Then they visited dangerous websites with unwanted cookies and offers to install toolbars and malware.

After the researchers were convinced that the system was infected and dangerous files were stored on the disk, the scanners were launched sequentially. The time it took to scan the system, the number of samples detected, the threat information provided, and the proposed solutions were recorded. The scans were performed on a 20 gigabyte partition with 17 gigabytes of occupied space. The test machine was running Windows 10 with Windows Defender disabled, and 17 malware programs were forced to run on the system.

One of the real online scanners. However, you cannot run the scanner in all browsers. Bitdefender QuickScan supports Internet Explorer, Mozilla Firefox and Google Chrome. Distinctive feature scanner is high speed work - checking the test system took less than one minute.

Unfortunately, Bitdefender QuickScan simply tells you whether the system is infected or not and does not tell you the name of the active threat. None Additional information the user does not receive, he is asked to install a 3-month trial version of Bitdefender Internet Security to disinfect the system.

This tool works quickly and seamlessly, but represents of dubious value for users. Other vendors offer more interesting alternatives.

Cloud scanner, which is presented as a standalone program, available for download and installation on Windows computers. You will immediately notice that the scanner looks more like a full-fledged antivirus solution. User interface offers a large number of options and settings, as well as several types of system analysis: quick, full or custom scans.

A quick scan of the test system with Comodo Cloud Antivirus completed in 2 minutes, and only one malicious sample was detected. This is a weak result, so an additional full scan of the system was carried out. This time the scan took 59 minutes, and Comodo was able to detect 13 out of 17 malware.

Comodo Cloud Antivirus is one of the few antivirus scanners that can remove detected threats. Users appreciate this feature.

One of the best online scanners. The product is available as a standalone Windows application that can be downloaded and run on your computer. Before execution ESET scan automatically downloads the latest signatures to your computer and allows you to configure scan settings. By default, ESET Online Scanner is configured to perform a full scan of your computer: RAM, startup objects and local disks. The user can set automatic cleaning of detected threats, scanning of archives, and scanning for potentially unwanted applications.

A full system scan took over 29 minutes and ESET was able to recognize all 17 test samples. For each individual malware, ESET displayed the name and path of location. It is noteworthy that after the scan is completed, the user can configure the removal of scanner files from the system.

ESET products are promoted discreetly and unobtrusively. ESET Online Scanner copes well with the tasks of a secondary scanner and demonstrated high efficiency in the test.

Another standalone program that needs to be downloaded and run first. Before performing the scan, the product downloads the latest signature definitions.

F-Secure Online Scanner then begins scanning the system for malware. The user cannot configure anything and cannot select the type of verification - the entire process is performed automatically.

If F-Secure Online Scanner detects infected files, the product asks you to reboot the system in order to clean up the threats. If you wish, you can view information about the location of threats, the total number of infected files - if this is not enough, you can go to the website to obtain additional data about the files found malware.

F-Secure Online Scanner is one of the fastest scanners, scanning a test system with a 20 GB partition in less than a minute. F-Secure ultimately detected 12 out of 17 viruses.

Another scanner in standalone application format. The program has a simple and clear interface and allows you to perform quick or full system scans and even schedule regular scans. By default, the tool checks the system twice a week. Unfortunately, you cannot change the frequency of checks, but you can specify specific days of the week when they should be run.

A quick system scan took 2 minutes and resulted in 2 threats being detected. The full scan took 52 minutes, Kaspersky detected 9 malware.

Scan results are presented in several categories:

• Malware - all detected infected files
• System protection - shows whether it is installed on the system antivirus protection
• Other problems - configuration problems are displayed Windows Explorer And Internet browser Explorer.

If you want to remove detected threats or fix detected problems, Kaspersky Security Scan will redirect you to the vendor’s website to download a trial version or purchase a commercial solution.

Has a long and complex name, but is really very simple application for Windows, which scans your computer for threats and security issues. McAfee Security Scan Plus automatically updates its files upon startup, and the product scanned a test system in less than a minute. Unfortunately, the user cannot set scan parameters. IN test system McAfee found only one malicious file out of 17.

It's hard to find reasons for regular checks computer from using McAfee, but McAfee Security Scan Plus provides this option. The user can schedule checks at their convenience.

McAfee Security Scan Plus does not offer a cleaning function, so the only sample it detected remained active on the system. When you select the protection option, the tool will redirect you to the McAfee website to purchase a McAfee Total Protection subscription for 3 computers. Don't you think this is too much for one infected device?

A desktop application that needs to be downloaded and installed on your computer. When launched, the program automatically downloads the latest antivirus definitions and scan engine updates. Norton Security Scan checks systems not only for malware, but also for suspicious cookies and potentially dangerous applications.

When you hover your mouse over a detected threat, Norton displays detailed information about her. After installation, Norton Security Scan automatically starts scanning the system; on a test machine, the product detected 12 malware in 2 minutes.
