Hi, traka,
Thank you for the information.
Could this possibly be a spyware worm? Instead of a true virus worm?
If you have AdAware_SE and Spybot, if not already run in Safe Mode, try running them to see if they find anything.
Also, here is a link to a great, free, program that stops spyware (if that's what it was) before it gets into the computer. It does not require scanning, but does require updating every week or so with new "definitions".
It's called Spyware Blaster 3.3:

So far, in months of use, nothing has gotten passed it!
Best wishes,
