McAfee scanning schedules

I have decided to change back my scanning schedule to 4 am Sunday mornings. It says you can conserve your battery power to set the scan to run only when the the PC is plugged in. The PC is always plugged in but I switch it off at night, do they mean it just has to be plugged in or does the PC have to be switched on, in other words will the scan schedule work and run on battery power or whatever. I had a look at my scan history (I think!) and it looks like it didn't scan last night (this morning).

Thanks.

Your computer won't miraculously start up at 4am just to run your scan. If you turn your computer off overnight, it will never scan at 4am.
Your computer must be running, and plugged in (if you set that setting).

Change your scan to be at a time when your computer is on, and when you aren't likely to be using it, like lunchtime.

As a rule when I wish to scan I leave the computer on when I go to bed .Return in the morning scan done or set the scan going before going to bed. tkf

Ta, I thought it might run in the back ground just by the back up battery!!! mine seems to take hours hence the change to the small hours of the morning, maybe I'll just leave it running all night on Saturday through to Sunday.
