The following tutorial demonstrates how to turn on and off the Tamper Protection for Microsoft Defender antivirus when using a version of the Windows 11 operating system.

While Microsoft Defender in Windows 10 became more than reliable antivirus protection in general, it was not entirely without its faults. For instance, one of the problems I noticed on my own computers was that they would randomly have the antivirus turned off without my prior knowledge. Given my experience in malware — I write lots of antimalware tutorials as well — I knew this was not likely to be Microsoft’s doing but rather a deliberate plot from malicious software to try to gain access to my computer without the antivirus being turned on.

Given my browsing habits, which I must admit does at times include my downloading of torrents that I should not, it was hardly surprising that I had accidentally installed such malicious apps from time to time. But what did surprise me a little was that the operating system itself could not prevent this one way or another.

In Windows 11, we are finally given an answer as to whether or not the malicious apps can be prevented from turning off your Microsoft Defender antivirus protection, and that is a yes, with the help of a dedicated Tamper Protection toggle, which is an entirely new feature that has been added to the main Windows Security interface.
