?                               A Basic Virus...                              ?
???????????????????????????????????????????????????????????????????????????????

Well, here's a basic virus.. Nothing complex, very (very) BASIC. It attaches
itself to .EXE's and is non-destructive so non-programmers don't fuck around
and mess up shit.  It should run under GW-BASIC, and it works in QuickBASIC.
Remember the length of the compiled and linked .EXE file and edit the source
code to place the length of the object program in LENGHTVIR varible. BV3.EXE
should be in the current directory,COMMAND.COM must be avilable (SHELL=) and
remember to use the /e  switch when compiling.  Anybody with BASIC knowledge
can make this a major fucker.
