AVG Support Community
Same issue as everyone else. Yesterday I had no issues. Today I had no internet access unless I DISABLED the AVG Firewall. Different PC has no issues but is running Windows 7 Ultimate.
It took me a couple of hours to narrow the problem down to AVG. As far as I can tell there was no upgrade performed last night so I cannot understand why this would happen all of a sudden. I didn't even reboot my system before this happened.
I am running SysInfo as recommended in every other comment and have sent it in.
NOTE: I did find a post from Isaac Sogunro and following the steps he outlined, it appears that the firewall is back up and running properly (for now). Hopefully, this fixes the issue for good.
Hello I am having the same issue.
Windows 10 - just updated
AVG Ultimate - firewall blocks all internet traffic. Tried setting it to interactive and no alerts come up and can't use the internet. Had to diable the firewall to be able to get online.
The Windows 10 updates that ocurred today were:
Security Update for Microsoft OneNote 2013 (KB3115256) 32-Bit Edition
Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB3176495)
Security Update for Skype for Business 2015 (KB3115431) 32-Bit Edition
Security Update for Microsoft Outlook 2013 (KB3115452) 32-Bit Edition
Windows Malicious Software Removal Tool for Windows 8, 8.1, 10 and Windows Server 2012, 2012 R2 x64 Edition - August 2016 (KB890830)
Security Update for Microsoft Office 2013 (KB3115427) 32-Bit Edition
Security Update for Microsoft Word 2013 (KB3115449) 32-Bit Edition
Security Update for Microsoft Office 2013 (KB3114340) 32-Bit Edition
I also updated AVG Ultimate but the firewall still doesn't allow any internet traffic.
I've removed AVG completely and I haven't had any problems in the past week. I'm going to try to install AVG again to see how it takes for it to block my internet access.
I also had a Customer Services operator email me to say that they can provide a remote engineer to connect to my computer to fix the problem --- obviously this will not work if AVG is blocking my internet access.
AVG, I'll refer you to my original post, 10th Dec:
I've uninstalled (using AVG Remover), and manually deleted (app data, etc) and reinstalled AVG so many times now it's beyond infuriating. Each time, my internet connection works for a day or two, then everything becomes blocked again.
Is there an answer or and actual fix to this problem, or will I just be told to uninstall and reinstall AVG again?
