This may sound like a dumb question, but does my computer have to be on for it to do the scheduled scan at 4am? I have my computer shut down to the point that I am not online and in sleep mode but not totally off.
As far as I know yes it has to be on not in sleep mode. Try it set the time to now plus 10 mins and and set in navigation general settings and alerts and Settings set wait till Pc idle to unticked that way it will force a start if it can. see what happens. Put it in sleep mode and see what happens I am sure it should not start but interesting to try.
