Idle Time Scan Repetition

Whenever and without exception NIS 2010 is running an idle time scan whenever the system is not in use.  Again every time this happens, shortly after it starts, I get a red warning stating that it has found a problem.  It does not state what the problem is.  When I click on the area to show what it is, I am told it is Tracking Cookies which have been removed.  This scenario is happening many times a day and is very disruptive to my computer use.  Is there any way to stop, or a least minimise it, without totally turning off idle time scans?
