Hi Karen,

Yes, you sure have diagnosed it correctly!

Finally I was able to use the Trojan program you linked to and it found some stuff and cleaned it. But guess what?

Those pesky pop ups are still here :( !

They haven't (yet) hijacked my browser. I hope it doesn't get to that! I'm going to call the TrendMicro people on Monday( they have free phone support) and see if they can help.

Thank you for your help!
