> Does anybody have any information about OS/2 viruses.

There are currently no known viruses that run under native OS/2.
However, OS/2 DOS sessions are sufficiently compatible that many DOS
viruses function normally there.  So if your machine has DOS sessions,
you may get and spread DOS viruses. Even if your machine doesn't have
DOS sessions, it might inadvertantly serve as a vector for a DOS
virus, by transporting an infected DOS program, or an OS/2 program
with an infected OS/2 "fork" (the code that just prints "This program
requires OS/2" or whatever).  Also, an OS/2 machine can become
infected with a boot-record-infecting virus, since they are basically
operating-system-independant (they run before OS/2 is loaded).  For
technical reasons, existing boot infectors will not spread further
from an infected OS/2 system, but you still don't want the virus
around...
