NIS 2013 Patch installation makes me suspicious

Hi folks,

 

this morning NIS told me at the end of a Live Update session that a patch needs to be installed. This is totally new to me and it makes me suspicious that this might be not OK and does have its origin at Norton.

 

Does anybody know something about it? Is it OK? What does it do?

 

Your feedback is highly appreciated.

 

Thanks and kind regards,

Stephen
