Windows Defender is built into the Windows operating system. No need for a second AV solution. It can cause issues unless you’re using enterprise Defender and have it in passive mode.

I use Malwarebytes and don’t have any problem.

I do the same for my Windows 10 machines. But for Windows 7 I use Comodo free internet security program. I latched onto it a couple of years ago and I haven’t removed it. It still works just fine on W7.
