Tracking cookies removal in NIS 2010

I have just updated from NIS 2009 to 2010. In 2009 I never had to deal with tracking cookies. They were removed automatically. However, NIS 2010, I have to run a fast scan in order to remove them.

 

In the setup a parameter called something like "Scanning for tracking cookies", I have chosen to set it as "remove".

 

Is this an error ?
