   ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ

  Who says I'm not beneficial to society?

  I wrote this little utility to control the spread of virii on my system
  while I'm testing them. I figured I'd release a public version for the
  sake of mankind. THIS SOFTWARE IS *NOT* A DETECTION/REMOVAL UTILITY;
  WHILE IN MEMORY IT SIMPLY PREVENTS MY VIRII FROM LOADING THEMSELVES RESIDENT
  ONTO YOUR SYSTEM.

  How To Use
  ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ
  Execute VIROPROT.COM to install in memory [occupies less than 1k]. Each
  successive run will activate/deactivate it. Protection is provided for:

  OffSpring v0.82/v0.89
  ASexual v0.99/v1.00
  PinWorm v1.0-v1.7


  Gee, how'z it work ūirogen?
  ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ
  Each memory resident virus has it's own mechanism to detect it's presence
  in memory; if it didn't then the virus would eventually eat up all the
  system memory with hundreds of redudant copies of itself. While resident
  and activate, this program intercepts the virus's installation check and
  simulates the return of an already present virus, thus fooling the virus
  into thinking it's already memory resident, and so no need to install itself
  again.

  **SIDE-EFFECTS**
  ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ
  Some Anti-Virus utilties may indicate that one or more of the viruses
  VIROPROT prevents infection of are resident in memory. This is a false
  alarm; it's just VIROPROT's mimacy response to a called installation check
  for a virus.
  PinWorm [all versions] uses an original mechanism to detect itself, which
  has the unavoidable side-effect of removing VSAFE/VWATCH from memory.

  History
  ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ
  v1.0 - Distributed as PREVENT.COM -
         I wrote this for my private use a long time ago, and somehow it got
         spread around. This version may have had a bug in it which caused
         irradic system behavior [not sure though, who knows what copy got
         out].
  v2.0 - Distributed as VIROPROT v2.0 -
         ž Added ability to enable/disable itself in memory & more shit.
         ž Hopefully no bugs, I whipped it up pretty quick.
         01-11-95
  v2.1 - ž VIROPROT will now sound a beep when a virus installation check call
           is received and display the virus name at the top left corner of the
           screen.
         ž OOps. I made a little mistype and VIROPROT might interfere with
           the fetching of a child process's return code. This is fixed.
