Technical Details


Just like the "Stupid" virus, it will only work on machines with at least 640K memory. It activates on September 1st, and stays active until December 31st. While active, it will corrupt all disk writes, deleting the first ten characters of any data written to the disk and add ten "garbage" characters at the end. This will cause destruction of data files, as well as preventing the compilation of any programs.
