N360-How to stop automatic full system scans

I had an older version (~3 years old) of N360 that I recently upgraded to the most current version via dnlding from the website.  Without fail, after booting my machine and using it for about 20 mins, N360 proudly tells me it is beginning a full system scan.....and shortly after that my system grinds to an agonizingly slow pace, not usable, then it gets to the point that all system resources are starved/locked out to the point that keyboard or mouse movements are not responded to, at which point I usually end up power cycling the machine.

Is there any way to configure this full system scan to be done by user command?  I have searched many places and I can't believe what I am finding.

I'd love to meet the person who designed this sw using the premise that it is OK for his application to take my machine hostage and not give me any way to configure its actions....

Please tell me of a way, else my only recourse is to remove this sw.....

Thank you, and

best regards
