Scan EICAR
Select this option to have the ZyWALL check for the EICAR test file and
treat it in the same way as a real virus file. The EICAR test file is a
standardized test file for signature based anti-virus scanners. When the
virus scanner detects the EICAR file, it responds in the same way as if it
found a real virus. Besides straightforward detection, the EICAR file can
also be compressed to test whether the anti-virus software can detect it
in a compressed file. The test string consists of the following human-
readable ASCII characters.

Priority
This is the position of an anti-virus policy in the list. The ordering of
your anti-virus policies is important as the ZyWALL applies them in
sequence. Once traffic matches an anti-virus policy, the ZyWALL applies
that policy and does not check the traffic against any more policies.
