Hello. I've been previously infected with a svchost.exe virus that kept returning after each PC restart, I managed to remove those particular infections permanently, (I don't recall what I did unfortunately, because of current exams and I was impatient at the time) but another problem that I think was there initally still persists. Whenever I enter firefox, it occasionally starts stuttering at any time, which affects the computer performance in general. If I start up a game afterwards, it will run poorly. I'm guessing I didn't do a thorough cleanup, and now is as good as time as any to try and clean my PC entirely, considering my weekend just started. I'm not planning on doing any cleanup operations or installations, so I'll be awaiting a reply. Thank you in advance. dds.txt and attach.txt are enveloped in this post. dds.txt attach.txt
