Malicious Toolkit Website 4 False Positive?

Norton 360 for Mac
1

I have an iBook with MacOS 10.6.7 and Anti-Virus 11.1.2. Everything is updated daily and a daily scan has never found anything.

 

I have now have this:

 

Web Attack: Malicious Toolkit Website 4

Result: 81.200.64.50

Details: Outgoing

 

What does this mean?

 

Also, why did I not get a notification if I am supposed to be notified if an attack is automatically blocked?

 

Thank you.
