NIS 2011 Custom rules I never created?

My NIS recent history log shows that custom rules were apparently created by a user for taskhost.exe. However, I never created a rule for it, and I certainly don't remember seeing this in my previous history logs either.

 

You created custom rules to manage how host process for windows tasks accesses your network resources.

C:\Windows\System32\taskhost.exe

No action required.

User configured rules.

pc name (196.168.x.x.), 54066

Outbound TCP, www-http

 

 

I realize "taskhost.exe" is a a legitmate file, its the port "54066" and the "Outbound tcp connection" that worries me. Can anyone help me with this?
