Possible causes of the error:Virus scan failed

Today, many Internet users “pick up” somewhat unusual viruses that affect executable files, and even in such a way that not all anti-virus programs can cope with them. Let’s try to figure out what can be done in such a situation, and at the same time consider the problem of how to remove the “EXE” virus from a flash drive.

How do viruses that infect EXE files work?

The situation with the manifestation of activity of viruses of this type is not new. This has happened before. The most common computer Trojan pest today is called Virus.Win32.Expiro (versions “w”, “ao”, “bc”, etc.).

You can pick it up on the Internet quite simply, and then think about what to do with it and how to remove it. The virus deletes EXE files, or rather, makes them unavailable for execution. It is not surprising that when you try to open any program or application, due to the influence of malicious virus code, the system does not recognize the executable file and displays a message that such and such a file was not found.

The saddest thing is that this applies not only installed programs, but the first launch of the installer (this means if the distribution kit was downloaded from the Internet and is located on the hard drive). If you install a program from optical media, the impact of the threat may appear later, after the installation process is complete. It probably doesn’t need to be said that when you start the installation process from a USB drive, the virus automatically jumps onto it and infects all files with the .exe extension.

But the effect of a virus can only be recognized when the executable file is launched. That is why, until the file is launched, some anti-virus packages do not identify threats, and the presence of a virus is not detected at all.

Antivirus software problems

Let's see what and how to remove. The virus deletes EXE files or blocks them, in this case it doesn’t matter. But here, as it turns out, there is a double-edged sword. On the one hand, we are dealing with files being blocked by the virus itself, and on the other hand, anti-virus programs are reacting incorrectly.

For example, today there are quite a lot of cases where the same Avast package still detects a virus after a user-specified scan (and not when the threat initially penetrates). True, the definition boils down only to the fact that it shows infected EXE files and, due to the impossibility of treatment, deletes them indiscriminately. Here's the situation for you. It would seem that everything is simple: everyone knows what and how to delete. The virus does not even delete EXE files itself, but (paradoxically!) does it with the help of an anti-virus scanner. Naturally, such a pest is capable of creating copies of itself and masquerading even as system processes such as svchost.

How to remove a virus (EXE files are infected)?

As for combating such a threat, not everything is simple. First of all, most users can be advised not to use free antivirus programs and utilities such as Avast, AVG, etc. As a last resort, it would be better to have a cloud antivirus like Panda in the system.

Most the best option– powerful anti-virus software from Kaspersky Lab or ESET Corporation. By the way, you can resort to the services of utilities such as Kaspersky Virus Removal Tool, but first you need to write the program in the form of a portable version onto optical disk, using an uninfected computer for this, and run it from a CD or DVD media. Otherwise, successful treatment is not guaranteed.

You can also use small programs like CureIt, which actually treat infected files rather than delete them.

But since the virus, as a rule, “sits” in random access memory, the most optimal solution would be to use launch with optical media programs with the general name Rescue Disc.

They check all components of the system before it even starts. In most cases, this method is effective. By the way, this technique is also suitable for flash drives, only in the parameters for scanning data storage devices you will need to additionally check the USB drive box.

Conclusion

In general, I think some tips will help most users understand how to remove a virus. Whether the virus itself deletes EXE files or performs unauthorized blocking of executable files, you won’t immediately understand. But if there is even the slightest suspicion of its presence, it is highly recommended not to launch any program until the full process of scanning, disinfecting files and removing the threat is completed.

Among other things, it is advisable to have some package like Internet Security, capable of preventing the penetration of a threat at an early stage.

When working with any files, the user may encounter the message “The operation was not completed successfully because the file contains a virus or potentially unwanted program", after which launch specified file turns out to be blocked. The reason for the blocking is the system antivirus (usually Windows Defender), which has limited user access to the suspicious file. Below we will analyze the essence of this dysfunction and methods for solving it.

Microsoft is committed to combating malicious software and viruses. As a result, modern Windows 10 has a built-in antivirus, known as Windows Defender.

By default, Windows Defender is activated and constantly scans user software for potentially dangerous programs. If such a program is found, access to it is blocked, and the program itself malware may be quarantined. In this case, the user receives the already mentioned message "The operation was not completed successfully because the file contains a virus or potentially unwanted program", and running the specified file becomes impossible.

Such blocking can affect both a virus file and completely safe software that has been used for many years. In the latter case, this causes a number of inconveniences, since we cannot use proven software that we need for various tasks.

How to fix the “The file contains a virus or unwanted program” dysfunction

The simplest and most obvious solution in this situation is. But I would not advise rushing to disable such a thing, especially in a situation where your PC does not have a constantly running antivirus. In this case, you risk making your system vulnerable to virus programs, which will lead to its potential failure.

Check the startup file for viruses

First of all, to fix “The operation was not completed successfully because the file contains a virus,” I recommend checking the file being launched for viruses to make sure that Windows Defender is “swearing” at the file in vain. To do this, you can use either alternative anti-virus programs of the DoctorWeb Curate level, or upload the file to a specialized testing resource of the virustotal.com level for verification.

Check the file on virustotal

Add the problematic file to your antivirus exceptions

If the file turns out to be clean, you should add it to the exceptions of Windows Defender or the antivirus installed on your PC. In the case of Defender, it is recommended to click on “Start”, select “Settings” there, then “Update and Security”, then “Windows Defender”, and then “Open Windows Defender Security Center”.

A similar exclusions option can be found in the settings of other antiviruses.

Temporarily disable your antivirus

Enough effective way The solution to the problem “The operation was not completed successfully” is to temporarily deactivate the antivirus. In the case of Windows Defender, this is done as follows:

1. In the taskbar, click on the search button (with a magnifying glass), write “protection” in the query line, click on the found option “Protection against viruses and threats” at the top;
2. In the window that opens, find “Protection settings against viruses and other threats” and also click on it.
3. In the next window that opens, find the “Real-time protection” option and deactivate it.

Defender will be deactivated for some time, but later it may turn on again on its own (under the influence of the next system update). To prevent it from turning on, we can disable it using the system registry.

Do the following:

• Click on Win+R, type regedit there and press enter;
• Follow the path

• Hover over the empty panel on the right, right-click, and select New - 32-bit DWORD Value, name it "DisableAntiSpyware" and press enter;

Update problematic software

If antivirus software continues to signal that your software is unreliable, try downloading and installing the latest version. In some cases, this allows you to get rid of the “The operation was not completed successfully” error on your PC.

Restore Explorer functionality

In some cases, problems with the explorer.exe file can cause the dysfunction discussed in the article. Run command line from the admin, and type in it sequentially, not forgetting to press enter after each command:

sfc /SCANFILE=c:windowsexplorer.exe

sfc /SCANFILE=C:WindowsSysWow64explorer.exe

Running these commands can resolve the “file contains a virus” error on your computer.

Conclusion

The message “The operation cannot be completed because the file contains a virus or potentially unwanted program” indicates that the antivirus (usually Windows Defender) has found a potentially unsafe file. The optimal solution in this case is to add the problematic file to the antivirus exceptions, provided that the user is confident in its purity of this file. It is not recommended to completely disable the antivirus - this may cause potentially dangerous programs to penetrate the user's PC.

In contact with

Recently, in Windows 10 Fall Creators Update, I tried to download the file and could not, attempts to download the file using - Google Chrome, Microsoft Edge and Mozilla Firefox, ended in failure because they all blocked the file from being downloaded due to a virus that was discovered during a security check.

• Chrome displays a message "Error - Virus detected"
• Microsoft Edge "[file name] contained a virus and has been deleted"
• Firefox simply refused to start downloading.

A quick check showed that the built-in security tool is Antivirus program Windows Defender was indeed responsible for blocking file downloads on the computer.

In this case, I was confident that it was a false positive, and the following paragraphs describe how I tried to upload the file to the system.
First What I did was to launch Windows Defender Security Center to find out more about this threat.

Open menu "Start" by pressing the Windows logo key and start typing on the keyboard - Defender, in the displayed results, select the item "Windows Defender Security Center".

Windows 10 virus and threat protection

IN Windows Defender Security Center, click on the hamburger icon in the top left corner to display the menu section names next to the icons and select "Protection against viruses and threats".

Then press with right side to the link "Scan Log". Windows Defender may be telling you that no current threats. It may look puzzling at first, but Defender will only show you threats that require user intervention.

Since the downloaded file has been automatically quarantined, no further user action is required, which in turn means that there are in fact no ongoing threats.

After clicking the link "View the full magazine", you will see a list of quarantined threats. If you are lucky, you may see the name of the virus detected Windows Defender when it scans the downloaded file. In the log list, the name of the downloaded file is not specified, but the date may be enough to find a failed download.

Clicking on a log line displays a link to restore the file or delete it. Details display the file name, but this may not be sufficient for identification the desired file because Windows Defender may display a temporary name.

If user intervention is required, you will be offered options:

• Delete– Permanently delete a file from the system
• Quarantine– The file is moved to the Quarantine folder, and access to the file is blocked.
• Allow on device– The file, in our case, will be restored to the Downloads folder and you can access it

IN current version Windows Defender Security Center there are many problems in this regard. I already mentioned the lack of lock file details, but this is just one of the problems you may encounter.
The second is the fact that the Center Windows security limits current threats on this page to five. To view full list you have to click "view the full magazine", all quarantined items will be shown, but you'll immediately notice that there are no buttons to delete or restore files.

What you can try, if you are sure that the file you are downloading is safe, is to clear the history, disable protection and download again.

Turn off "Real-time protection" and download the file again. It is usually not recommended to disable system security features, but sometimes there is no other choice but to do so. So you can disable this setting for a short time, after which it will be enabled again automatically.

Go to section "Protection against viruses and threats" → to turn off "Real-time protection" and download the file again, this time the download will complete successfully.

Add the file you just downloaded to List of exceptions You'll find this setting on the Virus & threat protection settings page. "Protection against viruses and threats" → "Protection settings against viruses and other threats" → (you cannot do this before downloading it) and enable the Real-time Protection module again.

Conclusion: The whole process of unlocking files that are blocked by Windows Defender but that you want to download is not very simple and to some extent confusingly complex. Why is there no option for the user to delete or restore files in the full scan log, why does it take multiple navigations to find out more about the threat, and why is there sometimes no threat in the main interface when the file you want to recover is blocked?

I came across a curious innovation in the Google Chrome browser: at some point it took over the work of the antivirus and began to completely block the downloading of some archives and files, citing the fact that they contain malware and could harm the computer. However, there is no way to cancel the scan for a specific file. Below I will tell you what to do if Google Chrome blocks downloading files.

A little background

By the way, the downloaded file was fully functional and did not contain viruses. The browser protection worked, one might say, out of nowhere. The browser starts blocking malicious files

I am, of course, very grateful to the guys at Google for this concern and am quite confident that the browser's file blocking feature will help reduce the number of virus infections. But as they say, there is one small “but”.

I have always been a strict believer that every item should serve its purpose. The computer is protected in several levels, auxiliary software, as well as other types of active and passive protection. Again, I strictly adhere to and do not download any materials without scanning them in the background with a standard antivirus.

In this regard, the question arose: how to disable the annoying blocking of file downloads in Google Chrome? As always, everything is very simple! Step by step steps are described below.

Disable file download blocking in the Google Chrome browser

If Chrome still stops downloading

1. Go to the downloads directory. There is an unconfirmed file there (you can tell by its size).
2. Rename it with the desired extension. I restored it this way ZIP file, blocked by Chrome, and downloaded it for an hour and a half.

If that doesn't help, check out this article: . Perhaps it will be useful and help you.

Disabling blocking in the Google Chrome browser is only useful in some cases, since the downloaded file may indeed contain a virus or other malware, and if the computer is poorly protected, this can lead to problems. Do not disable the anti-phishing and malware protection function unless there is an urgent and, most importantly, conscious need!
