echo This will briefly give a little background on Protect! EXE/COM v.2.0.
echo
echo If you are a programmer, it is vital that your programs be well-protected,
echo especially in a world full of destructive hackers. That is why I created
echo Protect! EXE/COM. Unlike any utility on the market, Protect! EXE/COM scrambles
echo EXE and COM programs and checks for a CRC EVER TIME A PROTECTED PROGRAM
echo IS RUN! Since the loader is highly optimized, there is almost no noticeable
echo system slowing during loading. Of course, enough self-modifying code is
echo sprinkled in to really bug any hacker. In addition, the file is extremely
echo scrambled, but a CRC is just an extra precaution.
echo
echo If you already use LZEXE, PKLite (R), or PKLite (R) commercial, you may
echo think that you are sufficiently protected, but think again! UNLZEXE has
echo been out for a long time, PKLite can decompress its files, and any hacker
echo can get access to a program that can even undo compression done by the -E
echo option on PKLite commercial. Would you like any idiot to have the ability
echo to add "trojan horses" to your programs, remove some copyright screens, or
echo anything like that ? Protect your programs and your reputation by using
echo Protect! EXE/COM !
echo
echo This version in particular has many additional protection features which
echo are better summarized in WHATSNEW.DOC but add improved speed and security.

echo The one main requirement of Protect! EXE/COM is that the file to protect
echo be compressed with LZEXE, PKLite, Compack (R), or some other executable
echo compression program first if the file is an EXE file. COM files can be
echo protected directly if you prefer, but they you can compress them first also.
echo This compression requirement is instituted because a compressed program is
echo harder to decrypt than a program with lots of repetitive sequences. A CRC
echo can be calculated more reliably this way also. Sorry, but Windows (R),
echo OS/2 (R), and overlay programs cannot be protected.
echo
echo The cost of this revolutionary protection program is only a flat fee of
echo $25 -- no "run-time fees" or "royalties" at all. You can protect as many
echo programs as you want from one computer for that one fee, which will prevent
echo many people from snooping in your programs.
echo
echo By the way, this is the nice message that you get from a protected file
echo whose CRC has been violated (if a change occurs in the loader, the program
echo may crash, but if occurs in the data, you get the following message):
echo
echo CRC Error - File has been altered !
echo
echo
echo Happy EXE/COM Protecting!
