Are you sure it's malware, because SMART is also a predictive failure system for HDDs. It's just this side of useless, but that doesn't make it malware, or stop some people from getting a SMART failure warning and thinking that it's some kind of malware.
Maybe you could tell a bit more about this SMART error you're getting?
currently trying to get my system back. Running Windows XP 32bit. on a Dell Inspiron notebook. Safemode loads fine. I was able to download Microsoft Security Essentials. Did a quick scan and found several trojan viruses that were eliminated but did not clear up the problem.
I have myself and wife as users. was able to use here identity to get the security essentials downloaded and run. Shouldn't this also clear problems with my identity?
