I have no problem with the EICAR test since it's well identified and easy to
explain.  I can see how it might be considered beyond the scope of Nessus,
though.

The one that caused us problems for a while was the 42.zip test
(smtp_AV_42zip_DoS.nasl).  I know it was marked as a DoS test, and I was
prepared for the target system to be DoSed, but I wasn't prepared for the
message being relayed to our primary SMTP gateways.  A misconfigured Unix
virus scanner promptly choked trying to scan the attachment which caused our
production mail relay to back up quite badly.

I'm not sure of a good solution.  Maybe if the SMTP relay test returns true
for the target, the 42.zip test doesn't run?  Of course that would require
some other flag somewhere since I was running without safe checks and all
tests.

This is the only test I've run across that has unintended consequences
beyond the target system.  Are there any others I should watch out for?
