Just bought a 2nd hand laptop, and was listening to music when I noticed someone had remotely taken over the computer. I quickly disconnected the internet connect, but I guess some damage was done since directly after that, the previous owner's password was required to unlock the computer when the screen save turned on. I have disabled the screensaver and have changed the name of the computer. Since this was 2nd hand I don't have any of the original operating system discs, and really did not want to pay big bucks to by Microsoft operating system & office programs. I am running a Linksys router firewall. Any suggestions on how I can protect myself better, and identify what kind of damage might have been done by who ever got into the laptop?
