My computer is affected by spyware. The main problem is whenever I browse internet some of the IE windows pops up automatically. Where as I am using firefox latest version. I tried to remove those spyware and viruses, but the software (spybot search & destroy) I installed could not remove 100% spyware out of my system. and the other problem is whenever I try to install any other utilities software it displays some error msg. like:- "Invalid drive H:\" and installation terminates. I don't know what does it mean. Could you guys suggest me how do I overcome with these problem please........ I will highly appreciate your suggestions......... thanks
