You might be interested to know that even messages can have damaging viruses in them. On several local BBS's there have been Escape sequences that have redevined keys so as to when the sysop is in dos and hits a key, it starts deleting files and directories. The worst thing about this is that people have been able to do this for a long time. they are explained in the DOS Technical Reference manual. There are also rumors of a ZMODEM virus that spreads visa ZMODEM transfers, but I have not been able to find out very much about it, and it may be just a rumor.

we call those ansi 3.64 control sequences.... vt100 and other
terminals have similar if not exactly the same features... ansi.sys
implements a subset of ansi 3.64 without any protection the problem
has been known at various unix sites for years only now its starting
to show up on pc's because of the usage of ansi.sys and other programs
that recognize these sequences....
cheers
