AVG won't allow my computer to access internet

I paid for and downloaded the AVG protection and I cannot access the internet through the regular IE or my outlook.  I can access it through the explorer ap so it seems to be fighting with my MS Office programs.  I have tried to have AVG recognize the two problem programs but that step didn't.  I have AVG on my laptop using an older version of Windows with no problems.  My desktop runs Windows 8.
What is the fix?  I really want to be able to use the AVG I purchased.
