Q. Should I use more than one Windows 10 antivirus program on my PC?A. [Short answer - No.]
A. Installing more than one program to constantly scan and monitor your PC for viruses and other security threats can create problems, because the two applications will likely interfere with each other’s work. Clashing antivirus programs can cause the computer to behave erratically and run more slowly as the applications battle for system resources.
