How to prevent antivirus software from deleting.dll files

If your antivirus software is deleting essential files and restoring them, you’re probably wondering how to stop it. Most antivirus programs have a feature where they will delete files if they detect them as malicious. But if you have some files that you need to keep on your PC, you can add them to your Exclusions tab.

You can also use the Auto runs application to find out which files are being deleted by malware. You’ll want to write down the full name and path of each file you find suspicious. This is because some malware will hide under the name of a legitimate Windows process. So it’s essential to ensure you’re not deleting system files by mistake.

In the antivirus app, go to settings. Scroll down to “Virus & threat protection” and choose “Exclusions.” Click the plus icon and choose “File, File Type, or Process” as the exclusion. You’ll need to select the files you want to exclude from Windows Defender.

After you add the file exclusions, you can run a full antivirus scan to see if the problem is solved. In the meantime, if you’re still receiving the deletion error, it might be a File Explorer problem. If this happens, you can perform a repair on the file and then rerun the antivirus.

How to remove Trojan horse virus

A Trojan horse virus is a computer infection that can cause many problems. These viruses attach themselves to files on your PC or programs you download from the Internet. Once inside your PC, the Trojan will begin destroying files. To get rid of the virus, you must remove its files.

A Trojan horse virus usually appears as legitimate software. They are designed to spy on you and steal your data. Trojans also often download additional malware once they are installed on your PC. This malware will cause your PC to perform slow and even cause your programs to crash. If you’re unsure whether you’re infected, it is best to check your add/remove files and antivirus software.

Trojans may be challenging to remove, but the first step is to disable any suspicious startup items installed on your computer. Trojans are typically spread by the spam and advertisements that they generate. Fortunately, free antivirus software solutions will help you remove them. Using a free version of Windows Defender can help you eliminate any infections that may have been lurking on your system.

When you’re done removing the malware, you should make a backup of any files that were affected by the Trojan. This can prevent the malware from being able to infect other files. You should also use a Disk Cleanup tool to delete any temporary files on your computer. These tools will speed up your scan and remove any malware.


If you receive the Operation did not complete successfully because the file contains a virus warning, there are a few things you can try. If the file is not a virus, you can try to repair your old user account or try a different user account. This should help you see if the problem persists. If you still cannot open a file, you can always try to disable Windows Defender temporarily.

Another way to avoid this warning is to disable your antivirus temporarily. Occasionally, Windows Defender will detect a file with a virus, even though it’s legitimate. But in some cases, this is due to a false positive. So, if your antivirus is flagging a legitimate file, you can disable it for a short time until the virus is removed.
