What To Do When Windows Defender Keeps Deleting Files?

Windows 10 operating system comes with an integrated antivirus called Windows Defender, something that gives all its users an assurance that virus, malware and other threats won’t hit the system. However, there have been instances when users have reported some files being deleted by Windows Defender. You might wonder, when a certain file is not even a threat, why would Windows Defender delete it?

Although not a very common instance, Windows Defender sometimes treats a program or file as a threat and would not allow you to install it in the first place. In more extreme circumstances, it would just delete them without your prior confirmation.

So, if you have been facing this situation, you are at the right place. But, before we dash ahead with the possible workarounds, you must have another powerful antivirus in place so that even if you disable Windows Defender, you won’t have to jeopardize the security of your computer. One such Antivirus is Systweak Antivirus.
