I've been getting popups even when I'm not on the net. "your computer is infected with spyware"
And my home page keeps getting switched to about blank. I've tried adaware and spybot, they find the ussual cookies and reg files. but even after I clean up everything I still get the popups and home page switching.
I have installed anything lately so I'm not sure where to look. Anyone have any ideas?

If it's a gray popup window (gray background color) it's coming through the Messenger service.

There is a grey one and a yellow flashing one. I turn off messenger everytime I reinstall. So its not that.
any other ideas?
