Think i have a virus,nothing will update; security,windows,java etc. Keep getting redirected on every site i try to visit. (very frustrating)Tried to reinstall vista with reinstallation disc, dvr drive will not respond with vista disc but works with any other disc.Tried clicking f8 on startup but takes me to a password screen similar to normal password screen ,but it looks like its in safe mode and will not accept my user name or password.All i want is a complete restore but it will not let me! Please anyone help before i throw it off the roof!
