I do a short scan everyday and a full scan once a week.

Every 20 days

I plan to do it once a week but i actually do it in 2-3 months

Mine scans automatically every week

Every Sunday

It does it automatically at least once or twice a week.

Only like once a month, which isn't enough really, but there's never anything wrong

well i think it every 15 days

every couple of months
