I discovered my PC had become infected with malware/adware, I had Norton 360 up to date and I also installed Ad Aware 2007 freeware, found 200 infections (critical malware and tracking cookies). It removed all of them. I also read that IE addons are being used by hackers aggressively as malware/adware so I unistalled it. I also unistalled Ad Aware 2007 freeware, because the computer was very slow. My question is: I have to add that nvCpl.dll to my computer to restore Windows?
Can anyone tell me what I need to do now?
