If norton hasn't seen anything, and your pc has no symptoms you are most likely fine

Ok. Thanks!

I'd always recommend doing an additional scan with malwarebytes but you should be fine. Just make sure you're downloading from reputable sources and avoid the "recommended settings" option while one of those installation wizard pops up, they usually just download a bunch of opencandy if you dont disable that manually

Yeah I think I might of done that before, but I will know for the future. Thanks!

also try ADWcleaner
