I'm using Spybot ver 184.108.40.206 on a Vista OS.
I now have MS Security essentials running and also am using
System Mechanic ver.10.7.5
I turned to Spybot 2 after going through a bottle of aspirin trying to get rid of
a nasty virus (Vista antivirus 2012 rogue), following a third restore I set up spybot 2 and it went to work, then....poof no virus .... keeping my fingers crossed, its been 24 hours and no signs of the virus.
