Full system malware scan

[horrorific]

I've been using windows live onecare safety scanner but it looks like they're going to be taking it down so I need to find a replacement scanner that checks for all sorts of system problems. Virus, spyware, system errors, network scan. It doesnt matter if its one scanner or many I just need a reliable scanner(s) to check whats gotten into my system. Virus, spyware, system/disk errors, registry, and whatever else might be wrong.

I already use mcafee but my system has been acting really odd lately (freezing and crashing) so I wanted to do a full scan without having to download anything, mcafee didnt find anything so I followed my usual routing for this situation and went to try the safety scanner but its apparently being taken down
