Scan and detect
EICAR test virus
Click to have the Zyxel Device check for an EICAR test file and treat it in the same way as a
real malware file.
The EICAR test file is a standardized test file for signature based anti-malware scanners.
When the scanner detects the EICAR file, it responds in the same way as if it found real
malware. The EICAR file can also be compressed to test whether the anti-malware software
can detect it in a compressed file. The test string consists of the following human-readable
ASCII characters.
X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*
File size limit Set the limit of the file size the Zyxel Device anti-malware will scan. A file that exceeds the file
size you set here will pass without been scanned by the Zyxel Device anti-malware.
Destroy infected file When you select this check box, if a malware signature is matched, the Zyxel Device
overwrites the infected portion of the file with zeros before being forwarded to the user. The
uninfected portion of the file will pass through unmodified.
