Changes in Quick and Full Scans

Today I noticed some changes when I do scans

 

In My NIS 2009 History logs when I do a scan I no longer see entries for

an instance of "C:\Windows\System32\rundll32.exe"  is preparing to access the internet

I used to see anywhere from 2 to 7 of the same entries

 

when a tracking cookie is removed, in the detailed results, it used to show an entry for orphan cookie, it no longer shows that,now it shows and entry for null

 

When I used to do a quick scan, it used to scan around 4100 files, now it scans 5100 to 6100 files

 

Is anybody else showing these things
