'Scan Memory on Start' Explanation Required

Just after some clarity on this setting on the ‘Real Time Scanning’ tab.

At what point does CIS actually scan the computer memory? Does enabling this mean that cis scans memory during the computer boot up?

Thanks

here is the explanation from the user guide: Scan memory on start - When this check box is selected, the Antivirus scans the system memory during system start-up

Take and Happy New Year!
