This seems to be a conflict in the permitting the program to access internet;
If you are sure about the source of the program and want it to access internet; Do the following ;
Open security center , click internet & network , click configure(not the one which is next to about, the one above it)
Click Advanced for firewall protection is enabled
Click program permissions (to the left side)
Check whether you have the program (World of Warcraft ) is listed and allowed full access;
If not click "add allowed program" find the exe file of the program and add it to the firewall permission lists.
Click Apply and then Ok
Close security center and try to access the program.
I have attached a screen shot for your reference,
