You're welcome BDi..
I do this security stuff several hours a day, so apart from being able to fix people up, I also see the latest threats before a lot of the security program writers do. I'm sure the guys at Lavasoft and Kolla are working to get this particular nasty into the next update, so hopefully it shouldn't be a problem in a week or so... but it's nice to get in there first.
It probably got in by driveby download. In order to protect yourself against a similar occurence, go to
Start | Settings | Control Panel | Internet Options | Advanced(tab) and uncheck both the
Install on demand choices in the
Browsing section. It's not perfect, but it will help.
Cheers
