Somehow my Home page now defaults to "Searchdot.net" and I can't get rid of it. I've gone to internet tool and typed what I wanted and applied it...to no avail. It changes back to searchdot the minute I restart the computer (if left on it stays with my selection). I've changed the settings in explorer and that doesn't work either. Our computer rep suggested running adaware which didn't reveal anything...but there's obviously something running in the background because my computer will at times start running extremely slow. Typing in cntrl-alt-del does not reveal anything. However on a reboot...I kept hitting C-A-D to see what programs were launching and I did catch it at one time starting something as "unknown"...any suggestions?? Thanks
