I've set up BT Virus Protect on my mobile to run a scheduled scan every day at 03.30. It doesn't do that, but runs one some time around 23.30 (but that varies) the evening before and calls it a scheduled scan. Which I didn't schedule.
This is not entirely a problem, because it's good that there is a scan, and anyway I can ask for a manual one any time. But why is it happening like this? I've gone through my settings over and over again, tried every solution I can think of, looked at the MacAfee recommended solutions and tried them.
