Because virus threats can emerge quickly, having an outdated database of virus signatures could cause a virus to be missed. Thus it is very important to update your virus signatures regularly. Use the options on this page to cause SecurityGateway to check for virus signature updates automatically, to force an immediate check for an update, and to view the anti-virus update logs. NOTE: These options only apply to the ClamAV engine. The IKARUS Anti-Virus engine performs update checks every 10 minutes.
Virus Updates
Enable automatic virus signature updates
Use this option to configure SecurityGateway to check for updated ClamAV virus signatures automatically at a regular interval. You can choose to check for updates automatically either once per hour or once per day. The auto-update feature is enabled by default.
Hourly - At [xx] minutes after the hour
By default SecurityGateway will check for updated ClamAV virus signatures once per hour, at the designated number of minutes after the hour, specified in this option. For example, if you use "29" in this option then the hourly check will be performed at 1:29, 2:29, and so on. Click the Generate Random Time link to generate a random value for this option. A large number of systems check for updates at common times such as the top or bottom of the hour (e.g. 1:00, 1:30, and so on), thus choosing a random time could potentially speed up your checks for updates since there would be less traffic at those other times.
Daily - At [xx:xx]
Use this option if you wish to check for updated virus signatures once per day, at the time specified in this option. The time must be specified using the 24-hour clock format. For example, if you use "13:05" in this option then the daily check will be performed at 1:05 PM. Click the Generate Random Time link to generate a random value for this option. A large number of systems check for updates at common times such midnight (i.e. 00:00). Choosing a random time could potentially speed up your checks for updates since there would be less traffic at other times.
