Thanks for your kindness, Charles, but I've done a lot of stuff. including buying a new mouse, malware scans and system restore. All I'd like now is the name of the malware described in the article.

My backup plan is that a friend who is a computer professional has offered to come over and have a look at my machine. But if I can solve this without imposing on her, it would be nice.

Meanwhile, just watch. I'm supposed to have a fast system, but I'll click Submit and it will take ten seconds for this message to go.
