I am very happy with CHECKUP 2.1, which I got from SIMTEL20.arpa.  It is
shareware, but you need pay only if you are a commercial organization.
Otherwise you are able to register for free.  It calculates CRC's using
several different algorithms, so any virus that might be able to make a
program pass all the CRC checks through character padding, etc. would also
make the program not run.
