Thanks for your detailed reply. I guess you're right about that although The SpyGuard was one of 3 or 4 programs detailed on the MS Security Centre web page that kept popping up as the default home page on IE. Perhaps a bit misleading for the unwary. When Syguard didn't work, I loaded Malwarewipe and both the virus and trojan have gone.

I accept that the vendors are not to blame if I purchased the wrong product but some vendors do have a return policy. It's worth asking.

Right now I'm using McAfee VirusScan, Ad-Aware SE and update their signature files as often as they are available. In addition, there's Windows Firewall and now I have Malwarewipe, Peerguardian 2, and The Spyguard (currently unloaded). Do I need any others? Is the firewall you mentioned better than the Windows one?

Thanks again
