A few days ago, I used to have a RC of win xp pro 32 bit. Then i tried installing windows 7, and all went to hell. I pulled a cracked version from torrents, specifically named Microsoft.Windows.XP.SP3.Professional.March.2011 i installed that, and things are looking as expected, but can't shake the fact that cracked versions may or may not have viruses/rootkit. is there anyways to 99% ensure that i am protected, and the installation was clean? i have heard of using TDSSKiller or ComboFix, as typical malwarebytes won't catch any issues? i guess the main question is...should i be worried? Thanks!
