If I understand correctly, a rootkit is to be feared.
I used RootkitRevealer and got 3 worrying drivers dated October 2010 in Windows\assembly\GAC... "visible in Windows API but not in MFT or directory index". There are also 3 exe's in the same directories with the same description; + HKLM\Security\Policy\Secrets\SAC* and SIC* "key name contains embedded nulls(*)" (vd. attachment).
Let me add that I installed the operating system (XP) myself and have the disc, so if need be, I can just save everything to an external hard disc and do it all again.
Thanks for any help.
