keyboard problems after a trojan horse RRS feed

  • Question

  • I recently had a friend use my computer and after a routine scan using Norton it said I had a trojan horse and a downloader.  Went online on another computer and a website suggested opening windows XP H.E. in safe mode, doing a search on the msg I got from Norton, deleting all it found--which I did then reopening the computer in normal mode and emptying the recycle bin--which I did. I then reran Norton using the total scan, ran a Spybot scan and an Adaware scan.  The did a defrag and disc cleanup.  What remains is an in ability to use the keyboard "3" and often when I am operating, the computer automatically fills a series of 3333333333's into fields such as Google search or others till I stop it using the BKSp key.  I have found I can use the computer by going to Accessories, then accessability then onscreen keyboard.  Repeated scans, etc as well as searching the original link for the trojan produces no results.  I dont wany to use the system recovery disc but may have to.   HELP!!

  • Once your PC is infected with a computer virus or worm, your
    computer becomes compromised and nothing less than a reinstallation
    of the operating system is going to work.  Yes, you
    can scan and eliminate the initial virus, but you generally
    cannot undo the damage caused by the virus to the system
    files.  You'll need to reformat your hard drive and then
    reinstall your Windows operating system.

    After restoring your system, consider installing a good
    antivirus program, such as Windows OneCare.  You can
    try it absolutely FREE for 90 days.
