I seem to have picked up something called Tidy Network. (forget how I know...showed up in "Programs" or maybe cookies? But nothing I've done eliminates it.) It keeps popping up ads when I don't want them, and tagging words in sites that don't link to anything. As I have a website, having these tags all over the blog is NOT helpful. When I googled this, Symantec had a solution--use Norton Power Erase. But I don't use Symantec. And I've scanned the computer with ZA and nothing has been found.

Do you have a solution for this little critter?
