Notes About the Zyxel Device Anti-Malware
The following lists important notes about the anti-malware scanner:
1 The Zyxel Device anti-malware scanner can detect polymorphic malware.
2 When malware is detected, an alert message is displayed in Microsoft Windows computers.
3 Changes to the Zyxel Device’s anti-malware settings affect new sessions (not the sessions that already
existed before you applied the changed settings).
4 The Zyxel Device does not scan the following file/traffic types:
• 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 Zyxel Device is not
the endpoint (pass-through VPN traffic).
• Traffic through custom (non-standard) ports. The only exception is FTP traffic. The Zyxel Device 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 Zyxel Device does not
support.
