NIS 2010 - Compressed file question.

Hi all:

 

I have a compressed .RAR file that I can right click and scan - the result shows zero detection.

 

Now, when I extract the files from the archive, a Trojan threat is detected.

 

Why is that?

 

Just FYI - Compressed File Deletion is turned *off.*
