NIS 2011 - Norton Monthly Report - Incorrect Reporting?

Hi there:

 

Here is a picture of my Norton Monthly Report, which popped open today:

Notice that under "Network," I am notified that 2 intrusions have been blocked. Upon clicking on the link, I am taken to the Security History -> Internet -> Intrusion Prevention, where no reference is made to an actual intrusion.

 

Went through the entire log.

 

The same applies to Computer. No threats were detected in all the Security Logs within the past 30 days...

 

How can this be?

 

Additionally, when does the 30 day reporting period start?

 

Jon :)
