Updated AVG, and now it blocking my emails and internet connection

Hello Monique,

We apologize for the inconvenience. We'll certainly look into this and help you.

If the issue persists, please repair your AVG Internet Security and check if the issue persists.
Refer to this article to repair your AVG Internet Security.

I upgraded all 3 of my computers on Friday. And now only one of the computer, doesn’t connect to the internet nor allowing me to download my emails. When I switch my firewall off, then it all works again.
Could you kindly inform me what I need to do to fix this. I can’t keep my firewall switched off for my computer to work.
I noticed the UI version is different on the computer that isn’t working correctly compared to the ones that are working. Not sure how to upgrade that.
 
Hi Midhun

Unfortunately the above did not help at all. I found a question above which was the same problem as mine and used the answer posted...Open AVG, click Menu -> Settings -> Full Protection -> Enhanced Firewall. On the right hand side, tick the checkbox against 'Internet connection sharing mode' to enable it.

So far it is working and I hope it stays like that. Thanks
