Help. Suspected virus. Security Center Won't Scan or update, downloading results in error (windows has found a problem)

My PC started acting weird.  First it would stop for a few seconds, then it starting disconecting from the internet, and had other online issues with pages not loading.  Today I turned it on and it ran chkdsk, found a bunch of error, moved, and fixed files (don't recall exactly).  It would then not let me connect to the internet at all.  Antivirus would not start, crashed, etc.  I eventually formatted the hard drive and reinstalled Windows (Vista Home Premium 64).  I immediatly installed Mcafee from a download at mcafee), after much trouble and many reboots.  It kept giving me errors that the "windows found a problem with this file" - "unknown publisher".  I receive this error with any antivirus software or scanning utility.  I eventually got mcafee to install.

Now when I run mcafee security center, it says real-time scanning is disabled.  When I turn it on, it turns itself off immediatly.  When I attempt to do an update, it says cannot update.  WHen I click scan (quick or complete) it says an error has occured.

I get other errors like IE stopping, DNS client stopped working, etc.

CHKDSK shows 16 lg file records, 44 reparse, 93318 index entries etc - it goes by to fast to catch everything (even after format chkdsk runs).

I have never seen a hardware failure act like this so I suspect it is a virus.

Please help - I have spent two days trying to figure this out.
