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.
