How to Enable the Virus Scanner

  • Last updated on

The firewall scans traffic for malware on a per-access-rule basis when virus scanning is enabled. If a user downloads a file containing malware, the firewall detects and discards the infected file and redirects the user to a customizable block page. You can combine virus scanning with SSL Interception and Advanced Threat Protection. A Malware subscription is required. 

Before You Begin

Step 1. Enable and Configure the Virus Scanner

  1. Go to FIREWALL > Settings.

  2. In the Firewall Policy Settings section, enable TCP Stream Reassembly.
  3. Make sure that Application Control is enabled.

  4. In the Virus Scanner section, set Enable Virus Scanner to Yes.

  5. (optional) Click Show to configure Advanced Options.

  6. Click Save.

Step 2. Enable the Virus Scanner in Access Rules

Create or edit an access rule for the connections that you want to apply virus scanning to. Virus scanning can be enabled for all Pass and DNAT rules.

For more information, see How to Configure Virus Scanning in the Firewall for Web Traffic, How to Configure Virus Scanning in the Firewall for FTP Traffic, and How to Configure Virus Scanning for Mail Traffic.

Monitoring and Testing

You can test the Virus Scanner setup by downloading EICAR test files from http://www.eicar.com. The block page is customizable. For more information, see How to Configure Custom Block Pages and Texts.


To monitor detected viruses and malware, go to the BASIC > Recent Threats page.
