Hope you get along fine DJex...later if you something i can help add me to msn and ask for ti...who knows maybe i can help...

I guess it works on the same way like a virus scanner.
it search for an identification string (just search for something unique) in the file or it works with the crc-checksum.

i dont think it uses crc, MD5 would be a lot more effective, as the MD5 hash is longer iirc.

Actually, there's a problem with MD5: it's vulnerable to collisions. SHA-1 isn't, however.
Just found that out today (via a post on this forum I think).

MD5 is "vulenrable" to collisions, but they are few and far between and it would be hard to inject code into such a setup. SHA-1 is just a better algorithm. Either way they do the same thing, There just CRC gerneators with fancier methods.

no offence to say this to you but there is enough spyware scanners out their allready microsoft is very good and spybiot search and destroy is amazing....i guess my question is how do expect us to use that when we all got these very effective programs allready?? im not trying to be mean but it sounds like a wasted effort

Actually, any CRC algorythm is vulnerable to collisions, the only thing (almost, if you don't consider the subtle variations of the generation method) that makes a real difference between two CRC is the size of the unique ID it generates. The bigger the ID, the less chances of collision. As far as I'm concerned, anything past 64bits is pretty much useless .

Well good luck, although you should probably do some research on which algorythm is the best for your use. Then I'll just grab my network services "Spyware Laptop" (don't ask) and I'll let you copy all the files off of it.
