    then running your antivirus scan. Many times this error pops up when a 16bit
    program is trying to run outside the normal 16bit memory allotment. Some trojans
    have been known to do this.
    Other possible culprits are some automatic software updaters, like printer drivers
    and such, that have become corrupted and may need to be re-downloaded and
    installed. Another culprit is World of Warcraft installer/updater being corrupt.
    Redownload the updater (if that is what is running) and try again.
    But first, run the antivirus scan booted to safe mode!
