i have a computer running windows xp and have some sort of hijacker virus on it,
(I open internet explorer and the homepage changes after a few clicks, redirects, and if i try to open my yahoo inbox it redirects me again to a red screen that say my computer is infected, I installed msn explorer to try and get my yahoo mail and it works in that browser but if I go to ie it comes back)
i downloaded the avast virus cleaner but cannot open the file or any antivirus or firewall for that matter
help :'(
