Have you tried avast? That's what i use on my pcs. It works pretty darn well and it's free. Gotta like free. If that doesn't help let me know, I've got a few other things i use that may help.

Malwarebytes is a great program. I downloaded it after it was recommended to me by an IT guy at Chicago Police Department. He also recommended a program called CCleaner. I use both on an eight-year-old laptop I somehow resurrected and still use to this day.

If you need any suggestions or pointers on either program, I'd be happy to help!

Scanning once a week or so is a good idea. I think you can put MSE on a schedule so you don't have to manually scan, but that requires leaving your computer on during the scheduled times. I used to leave my computers on stand-by (or set them to go into stand-by after a certain amount of time).

I don't use them as much as I did a few years ago, though, so I try to scan when I'm thinking about it.

Using "Disk Cleanup" and "Disk Defragmenter" will also help keep your hard drive from running slowly or crapping out entirely for a long time.
