I have run Spybot, Adaware, spybot blaster and zone alarm which has removed most of the trojan visus and the system now reads clean but i cannot stop greatsearch.biz coming up as my internet homepage despite trying to delete it.
i tried all that was suggested on the web link provided (thank you by the way) but i still cant shift greatsearch.biz as my homepage. When i run spybot search and destroy it keeps finding DSO Exploit and XerOx. I can fix these but they both keep returning. Any further suggestions?
