Q. Should I use more than one Windows 10 antivirus program on my PC?

A.

Programs that do not constantly patrol your operating system, like mail scanners, may not be an issue.

When you install a third-party antivirus application on a Windows 10 computer, the Windows Defender Antivirus software should automatically turn itself off and make way for the new program to take over.
