I have recently been doing a major cleaning of my computer and all of it hard drives. I ran a full system scan using kaspersky, eset online scan, spyboy, ad-aware, malware bytes, etc. Overall I think there were under 15 trojans, virii, & malware found. They were all either disinfected, deleted, or quarantined. However since ive first installed kaspersky many months ago it has overall detected and cleaned(disinfected or deleted) 71 trojans, 3 malware, and 3 virii, plus a few more found by eset and the antispyware programs. Many of these were from keygens, cracks, files in software ive installed etc. Now im sure i have opened and run many of these before my system ever detected. My question is even though i have now cleaned them, is the system still infected by them since theyve been run? If so is there some way to find out and to clean them? Any help would be appreciated!
