Okay.
I know I'm "late to the dance" here, but I've read this whole thread to see if anyone has had a similar experience as mine (so I don't get flamed on my very first post for not reading through the thread before de-lurking ).
I've never tried to register at TSR, I've only visited their home page by clicking a link at a more reputable site (don't remember which). This was about three months ago. I was on the home page for mere seconds when I heard a sexy girl's voice coming from my speakers,and then my AV software kicked in (I use Avast, which sends up its flag in a man's voice.
The home page featured an ad along the right hand side of the page for VUMU (? I'm not sure...it's the chat software that uses sickeningly cute Bratz doll like avatars), and I thought that's where the voice came from, and thought it was the culprit. I ran Spybot (something I do religiously) and it reported that I had VirtuMonde gunking things up. My last scan (only the day before) turned up nothing. I removed the problem and deleted everything that could cause it to re-appear, and Spybot gave me a clean bill of health.
A few weeks ago, I got daring again and visited the TSR page. No VUMU ad, no female voice, but Avast kicked in again, and I got infected with VirtuMonde again.
I don't know if it helps or adds fuel to the fire, but I'm glad to see that there's an entire forum dedicated to this very thing!
Thanks!
