"Ultimate Packer for eXecutables".

Came across this program, sounds interesting enough

although I hope I'm not preaching to the converted.

UPX is a free, portable, extendable, high-performance executable packer for
several different executable formats. It achieves an excellent compression
ratio and offers very fast decompression. Your executables suffer no memory
overhead or other drawbacks because of in-place decompression


UPX is a versatile executable packer with the following features:

excellent compression ratio: typically compresses better than
WinZip/zip/gzip, use UPX to decrease the size of your distribution !


very fast decompression: ~10 MB/sec on an ancient Pentium 133, ~200 MB/sec
on an Athlon XP 2000+.


no memory overhead for your compressed executables because of in-place
decompression.


safe: you can list, test and unpack your executables. Also, a checksum of
both the compressed and uncompressed file is maintained internally.


universal: UPX can pack a number of executable formats:
atari/tos
djgpp2/coff
dos/com
dos/exe
dos/sys
linux/386
rtm32/pe
tmt/adam
watcom/le (supporting DOS4G, PMODE/W, DOS32a and CauseWay)
win32/pe


portable: UPX is written in portable endian-neutral C++


extendable: because of the class layout it's very easy to add new executable
formats or new compression algorithms


free: UPX is distributed with full source code under the GNU General Public
License, and may be used freely even with commercial programs.
You probably understand now why we call UPX the "Ultimate Packer for
eXecutables".

UPX is based on experience with our previous packers DJP and lzop and uses
the NRV compression library.


Check it out,it's Compression Ratio is astounding.

Nice that you have discovered something useful and willing
to share. But, you are correct that many of us will have already
known about this nice piece of compression software. UPX
is fine, and yet there are others available that also work very well.
An earlier version of ASPack was available as freeware, now hard
to find. It also would compress .DLL and .OCX files as well as
executables.

That's why it is so popular among the premium rate dialer spammers for
shoving their programs into the throat of any unwary visitor on their
websites that uses Internet Explorer.

There are also worms which are compressed with UPX.

You can still get "ASPack 1.04beta" freeware from this site if interested.

*This beta of the well known Aspack was the last freeware version of this
excellent compressor for

executables (exe's and dll's), before it went commercial.*

So then,

should we get rid of cars,planes,boats and the like because

they kill a lot of people.

Maybe we should stay in bed every day for fear of something

bad happening to us.

Never turn on the computer, we might get spammed,download viruses

Dialers, Keyloggers Trojans and the like.

Well I've had to deal with them all,and I must say I'm pretty

good at it.

My original post was to point out the POSITIVE aspect of UPX.

Now if your so fearful about a few viruses,Trojans etc etc,

you might as well stop surfing the net.

There are also worms and viruses which are compressed with PKLite and other
compressors. What was your point again?

Oh, that's right. You don't have one.
