Really all you have to do is install a great anti-virus software program. I personally like Eset Smart Security (the entire internet suite) or just the antivirus software Nod32….they are the same company.
You do not have any antivirus on machine now?
To be sure (since you can not run antivirus from floppies any more), I remove HDD, put it in external usb hdd enclosure, connect to virus-free PC & do complete scan.
you can use AVG free.
If the drive is too infected, you might consider backing up user files & reinstalling Windows.
