I'm REALLY a newbie, so you whiz persons can't use all the tech language I've seen while browsing. But this scares me.

Husband said he saw the following pop up on the Dell with MS ME:

"The following users are connected to your computer (//DANDONA). Continuing will disconnect them. Do you want to continue? Yes. No."

Needless to say, we don't know any DANDONA. Ran a NAV scan, nothing showed. But then again, about a week ago, we got a message from NAV that it had caught a virus that it couldn't quarantine. But when we ran the scan, it didn't find anything! I probably haven't given you enough info, so please bear with me. Any suggestions?
