Most users know that .exe files can be potentially dangerous, but this is not the only extension to watch out for on Windows. There are many other extensions that can damage your system or files. Knowing about file extensions that can be potentially dangerous will help you understand how secure a file is when sent as an email attachment or downloaded from the Internet. Even the screensaver files can be a threat in Windows.

To start with, I recommend that you always install an anti-virus program that regularly updates its databases and runs in the background. However, knowing the information below will help you further reduce your risk of possible infection with any malware or virus.

Error Message: Operation Did Not Complete Successfully
Sometimes you may receive an error message saying “Operation did not complete successfully because the file contains a virus”. Why is this happening?

There are many antivirus tools available to you online, but none can completely stop the virus for you. There will always be malicious tools that go unnoticed and even the most expensive & popular antivirus tools can't detect these malicious tools.

Every coin has two sides. Even if your files are 100% legal, your antivirus tools may keep coming up with false positives. However, if you want to judge whether a file is genuine or not, the process can be delicate. You need to pay close attention if you try to deal with these files.

Before you confirm the file is a false positive, you need to scan the file with several different antivirus scanners. The error code that sometimes occurs underneath the message shown up in the title is actually triggered by Windows.

If you want to learn how to deal with this error, just follow the methods presented below.

Method 1: Fix the Issue by Disabling Windows Defender Temporarily
If the settings of Windows Defender are set to full protection, Windows Defender can produce some false positives, so it's normal for you to encounter a simple mistake like this.

When the problem involves Windows and Windows Defender, there is no effective way to actually run the reported file, and the only way is to disable Windows Defender completely.

Step 1: Type windows defender in the search bar and click Windows Defender Security Center to open it.

Step 2: Click Virus & threat protection to open it and click Virus & threat protection settings.

Step 3: Under the Real-time protection section and the Cloud-delivered protection part, switch the toggle to Off.

Step 4: Click App & browser control from the left panel, check Off under the Check apps and files part. You can also turn off SmartScreen if you think it will disturb your actions during which you wish to proceed.

Method 2: Fix the Issue by Adding an Exception for the Folder
If you are using several other antivirus tools besides Windows Defender, you need to know turning off one security tool causes the other to start acting. Fortunately, in order to fix this issue, you can simply try adding an exception for the file you want to run.

If the file is on a removable storage device, make sure the device is connected to the PC before opening your antivirus screen.

Follow the steps below to do this work.

Step 1: Double-click the icon of your antivirus on the Desktop to open its user interface. Alternatively, you can double-click the icon of your antivirus in the bottom right part of the taskbar.

Step 2: Find the Exception setting and add an Exception for the folder where the file is located.

In each case, be sure to select the correct folder location. Meanwhile, you can’t click on the file directly because you actually need to select the folder rather than the file which you want to add to the exceptions.

Method 3: Use Command Prompt to Fix the Problem with Windows Explorer
This may sound strange, but sometimes even the Windows explorer process is flagged as potential malware, which will prevent you from using your computer properly. Meanwhile, you will receive the “Operation did not complete successfully because the file contains a virus” error message.

Explorer.exe is a genuine Windows process, so you are not able to fix the issue by turning off antivirus or by adding explorer.exe to exceptions. There's an easier way for you to fix the problem associated with Windows Explorer.

Method 4: Use Control Panel to Fix the Problem with Windows Backup
This error can also occur when you are running Windows Backup. The “Operation did not complete successfully” error message will show up when Windows Backup encounters the problematic file.

If you have tried the methods above and scanned your computer multiple times, and you're pretty sure your computer isn't infected, the false positive could be caused by temporary Internet and cached files.

Before you try to run Windows Backup again, you need to delete these files on all browsers you have used. Right now, you can follow the steps below to clear browsing data for both Internet Explorer and Edge.

Extensions are classified as potentially dangerous because they can contain code or execute any command. The .exe format can be dangerous because it is a program that can do everything. Various multimedia files (photo.JPG, .PNG, music.MP3) are not dangerous as they cannot contain code. There are cases of specially crafted media that could exploit a vulnerability in the application by which it is usually opened, but these are rare cases and are quickly closed by developers.
