completed security activities dated in the future

It is June 23, 2011.

The System Insight page shows a threat detected June 27th, a system performance alert June 29th and full/idel quick scans on June 27, 28 and 29.

My Security History page verifys that scans have already been recorded for these future dates, one on the 27th and three on the 28th and 29th.

Norton doesn't tell me there is any problem with my system now or during these future dates, although it says the future scan on June 28th found tracking cookies and resolved them.

I have verified the computer date and clock are correct.

Recently the CPU useage alert keeps popping up as well especially when on internet.

 

WHAT IS GOING ON??

DO I HAVE A PROBLEM?

 

Please advise.  Thanks.
