I just wanted to say thank you for your efforts here and to share what happened to my PC the last few days. Perhaps it helps someone.
A few days ago while wanting to run a video file with Windows media player I accidently downloaded a malicious codec after which AntiVir kept alerting me to the TR/Vundo.GEN. I always got three alerts simultaneously which I then either deleted or put in quarantine. The 3 alerts poped up after exactly one hour of being connected to the internet and again every subsequent hour after regardless of what option I chose.
I found your site via google and read some of the Vundo removal forums and it looked quite daunting (lots of "download and runs" and "post scan files"). Having seen the "Must-Read-Before-Posting-Hijackthis-Log" I followed the steps as far as and including step 2 (the Panda scan part) during which a number of files were removed. So far it looks like all is OK now (no alerts for over two hours). It did take me the better part of today and hopefully I'm not counting my chickens before they hatch.
Hope this helps someone and, again, thank you for the tips.
Happy Dutch Maiden
PS: not sure in which forum this goes, couldn't find an "appreciation" thread.
