AVG anitivirus disable my internet connection after activation

Dear Sir,
     I am very annoyed, because after activating AVG antivirus my internet connection is completely cut off. I installed the latest version. Here is my order number: 934318153439. I had exactly the same problem with a first PC. Now I have two computers, neither of which can access the internet.

Very appreciate your promt help please.
