How to turn Windows antivirus on or off

When you install a new antivirus, the Windows antivirus program is automatically disabled . So if you want to disable it to install another one, don’t worry because the Microsoft antivirus program automatically disables it.

However, it is not a good idea to have two antivirus programs running on the same computer at the same time , since this can cause conflict between them, that is, neither will fulfill its antivirus function.

Also, we do not recommend doing without antivirus software, so it is very important that you always have a program that protects your computer from the thousands of malware that exist on the Internet.
