      AndrewFNAF I usually love Avast antivirus and have it on all my devices. HOWEVER, the installation is complicated and takes a lot of time, plus any update needs a PC restart. Microsoft Defender is free and part of the OS, with multiple scans. MA is better than Avast just in terms of installation, because Avast has many, many additional features that make it better.

      Free, built in, up to date, and doesn't nag you every 20 seconds to upgrade to fix CRITICAL SYSTEM PROBLEMS which are just some files in your Recycling Bin and a few registry items you can fix with CCleaner.
