Thanks, LOTR

After I posted that previous message I did a lot of reading round (should have done that first I know). Turns out I had Schmitfraud-C on my PC as well as the W32.Sinnaka.A@mm thing.

My McAfee Viruscan didn't detect either of these nor did Ad-Aware (both up to date).

I downloaded SpyBot Search and Destroy. This detected the Schmitfraud-C but couldn't clean it. It was always there when I re-scanned.

I then bought a license online for "The Spyguard" which was one of the recommended programs on the MS Security Center page. This also didn't detect Schmitfraud and kept crashing so I'm now asking for a refund from them.

Lastly, I downloaded "Malwarewipe" and this appears to have detected and cleaned both as well as a few other things I didn't even know I had and my PC is behaving normally now.

No sure what I've learned from all this except the problem seems to have been fixed.
