Notes About the ZyWALL/USG Anti-Virus
The following lists important notes about the anti-virus scanner:
The ZyWALL/USG anti-virus scanner can detect polymorphic viruses.
1
When a virus is detected, an alert message is displayed in Microsoft Windows computers.
2
Changes to the ZyWALL/USG's anti-virus settings affect new sessions (not the sessions that already
3
existed before you applied the changed settings).
The ZyWALL/USG does not scan the following file/traffic types:
4
• Simultaneous downloads of a file using multiple connections. For example, when you use
FlashGet to download sections of a file simultaneously.
• Encrypted traffic. This could be password-protected files or VPN traffic where the ZyWALL/USG
is not the endpoint (pass-through VPN traffic).
• Traffic through custom (non-standard) ports. The only exception is FTP traffic. The ZyWALL/
USG scans whatever port number is specified for FTP in the ALG screen.
• ZIP file(s) within a ZIP file.
• Traffic a server or client compressed or encoded using a method the ZyWALL/USG does not
support.
