- No wonder this thread has gone on and on to the point of
- absurdity! Richard has been trying to refute the wrong idea!
- We all know it's possible. The point is that the idea of a
- beneficial virus is inherently _silly_; that anything such a
- program would do is more effectively done any of a number of
- other ways with less opportunity for disaster.
-
-
- Please, smack yourself in the head a few times, your eyes are stuck! No one
- type of program is any worse than any other, any type of program can have 20
- bytes of code installed with a DOS call to format the current drive. If you
- knew what checksum would be used to check the file you could even make it
- match the original checksum and file size.
-
- If someone wants to get you then all they have to do is put a program where
- you will download it.. That type of dos call is totally undetectable because
- every program that loads a file from disk makes a DOS call and it just
- depends what the registers are loaded with before it makes the call.
-
- Considering that if someone wanted to get you they could go it with ANY
- program, why are you afraid of them modifying a compression virus? It doesn't
- have the capabilities to spread itself over networks or LANs etc.. If they
- were good enough to modify it then they would just write their own.
-
- The only other risks from this are to the user who installed the marker file
- and those risks are basically that the decompression routine gets garbled by
- a bad disk and fails to unpack a file, considering that the decompression was
- part of the file, the file would be lost anyway.
-
- A power surge could modify the recompression code in memory and it could do
- any dos function you can imagine, but then so could ANY program that makes
- DOS calls.
-
- Nothing is inherently evil about a virus, especially one restricted by a
- marker file.
