How to Enable the Virus Scanner

  • Last updated on

The Virus Scanner service supports two virus scanning engines: Avira and ClamAV. Although it is possible to use both virus scanning engines, it is not recommended because this can result in high system load. A Malware or Web Security subscription is required. The virus scanner can be integrated with the following services:

  • Firewall
  • HTTP Proxy
  • Mail Gateway
  • FTP Proxy

Enable and Configure the Virus Scanner

  1. Go to  Configuration > Configuration Tree > Box > Virtual Servers > your virtual server > Assigned Services > Virus-Scanner > Virus Scanner Settings. 
  2. Click Lock.
  3. Enable the virus engine(s): 
    • Avira – Set Enable Avira Engine to yes.
    • ClamAV – Set Enable ClamAV Engine to yes.
  4. (optional) Adjust the Max. RAM Cache (MB) to your preferences. Files exceeding the cache size are stored on the hard drive. Increase to cache more files in memory and reduce the I/O load on the firewall.

  5. In the left menu, click Update Handling.
  6. Set Disable Updates During Working Hours:
    • Yes – The firewall will not perform a virus scanner pattern update during the defined working hours because the virus scanning service does not respond to scan queries while it is re-initialized with new patterns.
    • No – Virus scanning patterns are installed immediately after they are available.
  7. (optional) Enter Update Every (mins) to change the update frequency. 
  8. To download the updates via a proxy:
    • Proxy Settings If the virus scanner requires an HTTP proxy to reach the update servers, configure the parameters in this section.
