Its like HUGE LIST of cracked games. All of them literally. is it safe?

First of all, if my post goes against any rules I hold no grudge for removing it. I'm just not sure where to turn for advice. A few days prior to finding/subbing here, I made a mistake. I only have one other post here about ACO stating I'd had trouble getting the game to work and I tried multiple sites for the torrent. One of these was nosteam.. I now have malware or spyware, I'm unsure. I've gone through and run avast, ag, defender, and a trial of Kaspersky to scan for it and haven't had any luck. Browser opens on its own to a handful of different websites... porn, foreign shopping, fake media, and pages asking for my pc information. Wondering if anyone here has a reliable program to scan/clean/protect for the future.

TLDR: I'm stupid, used a bad site, got infected. Need help finding a program to clean the malware because what I've tried hasn't worked this far. (If I must do a reset I will I would rather not as my back ups are fairly old).
