Question

i run virus scans on my computer constantly and it says i don't have any viruses or anything, but obviously there's some sort of problem if this page keeps randomly popping up without me even clicking anything. what's wrong? does anyone else have this problem? how can i fix it without paying to get my computer fixed?

Answer 1

Most virus scanners do not remove adware.  A good free spyware checker is adaware, http://lavasoft.com/single/trialpay.php
