Note: Updating antivirus definitions can cause a very short disruption in traffic currently 
being scanned while the FortiGate unit applies the new signature database. Schedule 
updates when traffic is light, for example overnight, to minimize any disruption. 

Note: You can only update antivirus definitions from the web-based manager. 

Once every 1 to 23 hours. Select the number of hours and 

minutes between each update request. 

Once a day. You can specify the time of day to check for updates.

Once a week. You can specify the day of the week and time of day 

to check for updates.
