NIS 2009 Scan Question

Hi

 

I noticed that my full scan with NIS became very quick taking only 7 minutes compared to over 40 minutes previously.

I looked at the deails and the most recent scan scanned only 140,000 files but skipped over 110,00 flies and there were only 207

trusted files.

 

So thinking something was wrong I removed and reinstalled NIS 2009. The first full scan took over 40 minutes and skipped

only 15,675 files.  A couple of hours later i decided to do a full scan again just to see. It again did a full scan in

just 6.5 minutes scanning 140,000 files but skipping over 110,000 files and there were only about 200 trusted files.

 

So is something wrong or is normal? I have never had a full scan complete so quickly before.

 

How do I fix it?

 

Thanks
