[s-cars] NAC - My pc is being used as a mail server, need help!

You may have gotten a rootkit virus, or whatever they're officially called.
Grisoft does have a rootkit removal tool for free on their website, I'd
check that out for starters.

I'd also try a commercial spyware program- I have spysweeper and the CA
Internet Security Suite installed on my PC.

I'm surprised that Symantec is not suitable for this kind of stuff- I'm
running Symantec Anti-Virus (the enterprise version) at work and it seems to
catch nearly everything. I have plenty of idiots at work trying to download
stuff and install stuff that they shouldn't be doing- group policy works
great for this, although I might have to shut off all web browser capability
if this gets any worse.

My Dad once downloaded some sort of virus or something similar that
basically killed his PC- I couldn't get it to boot to the desktop, it would
hang right before the desktop came up- I replaced his PC because it was
outdated already and not worth fixing.

Nice meeting you at S-Fest!
