3.7.2 Anti-Virus
Vigor router can offer basic virus scanning, destroying and cut off the connection between
questionable link and your computer for the files transmitted through specified protocol. In
addition, several types of compressed file formats such as .zip, .gzip, .bzip2 are supported
and can be scanned with this router. There is no limitation in the file size for the transmitted
(incoming or outgoing) file. With this feature, all the files processed with the protocol
specified in Anti-Virus web page will be scanned for finding out virus while passing through
the router.
Note:
Files with three-layer compression (the files are compressed with six times) also
can be scanned by this router.

This page allows you to set eight profiles for anti-virus scanning. These profiles can be
invoked through firewall configuration. It is recommended to build one profile at least. Thus
you will have selectable anti-virus profile settings in
Firewall>>General Setup
.
The Administration Message box allows you to fill in important notification directly for
SMTP and POP3 protocols. It will be saved as a file. While receiving an e-mail, the user will
receive an attached file with the content listed in this box.
To edit a profile setting, please click the number link under Profile. You can see the
following screen. You can check the boxes listed below for different operation respectively.

priority in filtering.
