Odd and Troubling Idle Full Scan Results

My weekly NIS 2010 Idle Full System Scan ran today, and I was surprised that it ran so quickly, scanned only about 30% as many files as usual, and classified about 2/3 of those as Skipped (usually an insignificant number are skipped).

So about 90 minutes later I initiated a Full System Scan maually, and the results were the kind I have always seen in the Idle Full System scan prior to today.

It’s troubling that the today’s Idle Full System Scan seems, well, screwed up. This has never happened before in 6+ months of weekly NIS 2009 & 2010 Idle Full Scans on 2 pcs.  Any idea why this might have happened?  I trust my pc to NIS 2010 (not that I don’t also follow safe surfing practices and use adjunct tools occasionally).  So ths really has me concerned.  I shouldn’t have to “babysit” NIS looking for oddball Idle Scan behavior.
