Scheduled full system scan question

NIS 2012
Vista home premium 32 bit desk top PC
Vista SP 2

Ok I have a full system scan scheduled to run everyday at 3:30am ( over kill, I know)

Ok so this morning my power must have gone out briefly around 1am and then came back on may have even just been a power surge. Anyway my PC turned off.
This morning I turned on the PC around 7:20 am.
I just noticed that a full system scan started around 7:40 am (and had completed in about an hour)

Anyway, just wondering why the full system scan would have run when it was scheduled for 3:30am. In the past if power went out before scheduled scan the scan would just be missed
Ran autofix and all shows fine

I have missed scheduled scans but never recalled the scan happening at next chance.
But my scheduled scan ran this morning at correct time. So way cool
Thanks dick Evans
