Hi, I just discovered this on a server as well. Did you ever find out what was causing it?
No, never got any replies, and as far as we can tell, it does not cause any problems.
Are they coming from 184.108.40.206 and 220.127.116.11?
I beleave that they belong to Nationalnet.com
On Server that McAfee is running in the task bar right click mcafee shield -> VirusScan Console; after that comes up right click "Access Protection" -> properties
All your McAFee rules will be listed and a place to Block and/or Report and/or Edit button to change them.
Hope that helps someone on how to access these rules and change them.
