NIS 19.2.0.10 Idle quick scan cancels itself!

Hello to all,

 

I've noticed a strange activity since I've upgraded to NIS 19.2.0.10 (via LU).

When the version 19.1.1.3 was running on my system, (XP SP3),  the idle time was set by me to 2 minutes, and there others were left at their default (10mins and 20 mins).

After each LU session, (also set to manual), when new smart virus definitions were downloaded, NIS 2012 after 2 minutes of inactivity was running a quick scan, about 3 or 4 minutes and I received a pop up window indicating " Scan completed. Quick scan. No threats found."

Every worked fine.

Also I have Norton community watch set to OFF and Idle time optimizer set to OFF.

After updated to the latest version of NIS 2012 I have a strange activity: After 2 mins of inactivity, NIS is running a quick scan, BUT after 2- 3 minutes it cannot complete.

In History window I have the log:  Quick scan canceled and if I wait 2 more minutes the Quick scan lasts about a minute and it completes. Pop window indicating: "Scans completed. No threats found".

I also noticed that in the performance graphics the first period where the quick scan cannot finish, is not recognized as IDLE, only the second.

So I guess that Idle quick scan is running in 2 parts.

Is this normal?

I have no other security software running on m pc.

Any help or suggestions are very welcome.
