recently picked up some sort of virus that redirects me after clicking a google search link. i've tried running avg and spyware doctor, which avg didnt pick anything up and spyware doctor found and removed, but they are back after the reboot. mbam will not install, not sure why. Also when doing a reboot, my screen goes black and i have to reboot serveral time to get a normal start up, but i think that is a different problem, like my vid card has gone bad. I need help.
