Why are you not just using Microsoft Defender?

I never cared for Norton, McAfee, and other big antivirus programs, because they are just so intrusive and obnoxious. I would be playing Oblivion, Morrowind, or Skyrim in fullscreen mode (many years ago) when the dang antivirus would decide it was time to initiate a scan I didn't ask for, which would sometimes lock up or crash the game. Or it would decide that it needed to ask me if I wanted to renew my subscription which was about to end in another week or two, and to heck with whatever I was doing at the time and whether I just wanted it to leave me alone while I played a game unless it actually was something really urgent and not just some sales pitch. Whenever I get a new PC, the complimentary copy and trial subscription of whatever big antivirus program came preinstalled on the PC is always the first thing to go.
