Norton created rules. Iexplore.exe port 8181!?

I found this in the log.

 

Under Security history I found this:

 

"Local computer: [my local ip number], 51556

Traffic description: outgoing tcp, port 8181"

 

Googling "port 8181" is not nice..., anyone know I could find out if this is malware which I highly suspect it is?
