I got a virus on my windows xp laptop. I downloaded avast! and it scanned my computer and found the virus. I made a mistake and hit "delete all" instead of "move to chest" and im pretty sure i deleted some files important for connecting to the internet. Im pretty sure its not because of the virus because i could connect to the internet before i scanned. All my other computers work. How can i fix this? I connect to the internet wirelessly by the way. Iv tried system restore but i keep getting error messages.
