I'm probably not posting this in the right place, but my laptop has been playing up for the last few months. It wouldn't let me download or save pictures off the internet for a while, and now it keeps coming up that my password is incorrect! I think there might be a virus, but I can't sign in to do anything about it! I'm not really that good with computers as I'm only fourteen but I'd appreciate any advice you could give me!
Thanks,
Nicole

Hello, Nicole... I am gooing to assume that you have XP Home.... Home will not show you the Administrator account unless you start in Safe Mode [this is the original account created when XP was installed]; further I am assuming that you, like most folk, did not apply a password to it....
So, restart in Safe Mode, select the Administrator account and press Enter for the password.... are you in? Good, bypass Sys Restore to go fully into Safe Mode, go to CP, Accounts and reset your password.
