The security appliance can scan for viruses over a multitude of protocols including
HTTP, FTP, POP3, SMTP, CIFS, NETBIOS, and IMAP. Because files containing
malicious code and viruses can also be compressed and therefore inaccessible to
conventional anti-virus solutions, the security appliance integrates advanced
decompression technology that automatically decompresses and scans the files
on a per packet basis.
The Anti-Virus feature supports virus scanning for one layer compressed files in the
zip, gzip, tar, bzip2, and rar2.0 formats.
Enabling Anti-Virus consumes additional system resources and may impact the
system performance. Go to the Status -> Dashboard page to view the CPU and
memory utilizations. To conserve the system resources, disable the service when
it is no longer needed.
