                FURTHER INFORMATION ON "FLUSHOT" FILES!

The program FLU-SHOT.arc has had "some" copies "BUGGED". Instead of
protecting you from the so called "COMMAND VIRUS"...they actually
erase Command interpreters and files!

I spoke to the author today. A new version of Flushot has been
released called FLUSHOT3.ARC. USE ONLY THIS VERSION ! Other versions
"M A Y" have been tampered with and be Trojan. To get a working copy
of the "GOOD" FLUSHOT PROGRAM call 212-889-6438 and download
FLUSHOT3.ARC.

If you have a copy of any other release...please check it out                

                          C A R E F U L L Y !

FLUSHOT3 is and excellent program....and has been installed on my
Board with no problems. I was NOT so lucky with the original version I
received. It had been tampered with and....erased over 15 files and
Command.com interpreters from my system and the systems of 5 other
users. Some had to completely re-format!

There "may" be other so-called "cures" that ( in actuality ) are
Trojan. ALWAYS test these programs before installation and BE SURE
they are OK!

WARNING: ON tampered versions of FLU-SHOT, most Bomb programs detect
no problems with the program...I know because I ran three of them
before installing to my system. After my disaster...I looked at the
program using various utility files. I can still detect nothing out of
the ordinary. However, looking at command.com (after the installation)
you will note "garbage" at the end of your current command.com file.
If you see this "DO NOT RE-BOOT YOUR SYSTEM! TAKE YOUR ORIGINAL DOS
BOOT DISK and COPY COMMAND.COM OVER THE OLD VERSION ON YOUR HARD-DISK!
I did not do this and....... you know the rest.

Good advice.  The file FLUSHOT3.ARC on SIMTEL20 came direct from Ross
Greenberg, the author of FLUSHOT.  I downloaded it myself from his BBS.
