Question about events recorded in security history

Hi:

 

I’m a new user of NIS 2011 and have a question. I’m constantly seeing the event shown below in my Security History. There always appears to be 2 instances of ccSvcHst.exe running on my machine – one instance under the SYSTEM User, and the other instance  under the name of whatever user account I happen to be logged into at the time. I understand the message but should I constantly be seeing it in History?

 

Thanks
