What Exactly Does Autoscan Do? Options

[Tonia]

Hi;

I am a bit confused about the Auto-Scan feature. What exactly is scanned during an automatic scan? My understanding (according to the manual) is that Bit Defender continuously scans files with Auto-Scan enabled, but what gets scanned? Do all files on my computer get continuously scanned (if so it seems like somewhat of a waste), or does it simply continuously scan items while I am browsing the internet, or does it scan any “new” items that are found since the last complete system scan, or…?

Any help would be appreciated.
