NOD32 v 188.8.131.52 Win XP SP3 The virus signature database is not updated while a screensaver is active. This is regardless of the update frequency set in the Scheduler. For example, if updates are scheduled every 2 hours, no update is attempted if the computer is left running overnight. If more time has elapsed than the frequency set in the scheduler, then database update is attempted as soon as the screensaver is deactivated by mouse or keyboard activity. Is this behaviour by design? I cannot find anywhere in the setup where this can be changed. Have I missed something? This is not a huge problem but it seems a bit strange.
