Avg firewall blocks internet in windows 10

I've had this same issue 3 times and just now - through this post - I have found a light to what may be happening. I have the paid AVG Ultimate anti-virus installed on my windows 10 laptop and I've had to reinstall windows 2 times already in just 2 months because AVG will not uninstall completely in any other way. I have lost entire days of work and I cannot see here (or anywhere else, for that matter) a definitive solution for this issue. Any alternative to having to reinstall windows on my laptop again? Please help…!

I'm an I.T. professional and have been using AVG and recommending it to clients for many years with few problems. Since the ZEN update I've been having issues with client computers as well as my own. Right after the update from the prior version on my laptop, the wireless stopped working. I'm using the FREE edition with NO firewall. There are no AVG protocols bound to my wireless adapter, but the second I disabled AVG the connection started working immediately.
I've had to uninstall / reinstall the product completely to solve some issues on client computers, which usually works. I haven't tried it yet on my laptop.
I understand every software product has technical challenges, but this version seems to have been released a little too soon, especially the product update module. Perhaps AVG should just perform a complete uninstall / reinstall during their update as a temporary fix.
I'll update if I find any additional fixes or information.

Hello Bel. I apologize for the inconvenience caused. Could you please let us know whether you have received any blocking popups from the AVG program and please check whether your firewall mode is set to automatic? Thank you.

What, if I disable AVG on the host PC, the one, linked to the router and modem, to resume Windows Defender, in lieu with Malwarebytes; and leave AVG operational on the Wi-Fi connected (second) PC?

Please, respond! I really need a feedback.

Thank you very,very much!

Abel,
I apologize for the delayed response. Please be informed that AVG 2017 don't use the "AVG Network filter driver" as previous versions. Please provide more details regarding what have you been experiencing with your internet. This will help us to assist further.
Thank you.

The only answer that really works is from Avinash, repeated below.
However, the only way AVG works is by disabling a part of it… That's funny (not quite!!)
Now I don't know if I am protected enough, because I disabled a part.

Maria,
Have you tried this steps mentioned below (provided earlier on this thread) to fix the issue?
Make sure the Firewall is disabled, then…

1. Open Control Panel
2. Open Network Sharing Center
3. Click the link to "Local Area Connection" in the Connections area on the right
4. Click Properties 
5. You should see in the list of items one called "AVG network filter driver" - if this has a tick, deselect it and then click OK
6. The remaining windows and then turn the Firewall back on - hopefully this should work!

I have the same problem! Every day I have to uninstall to get my internet back and the reinstall to be protected, which costs me about 30 minutes of my working day. ´This is intolarable! I use the FREE version, but was going to buy the full version. Unless this problems is fixed within the next 2 days, I am going to buy McAfee. I can't NOT be protected and I can't NOT be connected to internet. Please advise.

Horrible software, sorry but this has caused us so much damage!

Blocking all traffic through browsers and we thought it was caused by update from Windows 10.

I cant really see why this hasnt been fixed from your end.

Hi there,

I, too, am having the same issue.

Talked to an AVG rep over the phone, who advised me, after disabling the Firewall, to uninstall AVG and install it again. 


however, after reading the above correspondence, I am not sure that this would work. 

I'm sharing two PC's. The host, the one connected with the router and modem is in Windows10 and it's experiencing the problem.

the other PC, in windows7 (with avg 2015 and Malwarebytes, as the first one) is working just fine over the wi-Fi.

ideas, please!

Thank you in advance for your time and consideration with regard to that matter.

Same issue, using paid AVG. Never had an issue with the free version. This is very frustrating especially considering from this thread alone we can see its going unresolved for a year now at least!!!

Hi
Same issue here.  My LAN connected PC works fine then loses ability to connect to the Internet. Turn off AVG Firewall and it comes back again. Turn firewall back on it seems OK for a while, then loses connection again.  Repeat. Repeat. Repeat. How to resolve please?​

Hello Phillip,
We certainly understand how frustrating it is to have to go through this and we regret the inconvenience that it has caused. Could you please let us know whether you could able to get connected to the Internet after disabling the AVG program?

Unfortunately, I'm having the same problem as everyone else here. I was using the AVG Zen Pro free trial… Once this expired I began to get a notification saying License expired please activate. I then tried to uninstall AVG completely so I could reinstall the free version, however, everytime I tried to uninstall or repair it there would be an error message and it would fail. Consequently, I bought an AVG pro license and managed to log in and now AVG works… but my internet doesn't work on either firefox opera. They are both allowed in the firewall's allowed programs list and the only way I can get online is to disable AVG. I have tried plugging my desktop into two different routers with two different ISP's and neither work. Yet both routers work with my other devices. I tried the instructions here: http://avgread.me/1cgDhdU which also didn't work. Please help.

Has anyone consider this to be related to the Windows 10 1511 update?

I am trying to uninstall the AVG protection and the uninstalling app does not succeed with the error 0x0782. I am going to find the code via phone as I still not have internet connection on my Windows 10.

I have had this same problem for a few days, i deleted avg and installed the new version of internet security, the problem fixed then windows did an update overnight and so did AVG. now my internet is screwed again. HELP this is driving me crazy!

Just had this issue and spent about a day and a half looking online just to find out my issue was a simple checkbox.  First, I uninstalled all instances of AVG.  Next, I went to Network and Sharing Center/Ethernet/Properties.  There's an AVG network filter driver that I had to deselect.  Internet worked immediately.  Then downloaded newest version of AVG.

Useless! Keeps blocking all of my Internet connections, even when I disable the firewall. Removed from my computer as soon as I could. I want a refund as this software is not fit for purpose. You have been aware of the issue since at least August 2015 and this still has not been resolved? What kind of development team do you have??

To AVG TEch Support team,

If you are just to say sorry and asking us to try repair, uninstall and re-install solutions, you can forget it and go fly your kite! So deeply disappointed with the quality of your software. Getting worse with each new version. I thought initially the problems came from my modem and/or router. But after wasting so much time troubleshooting, getting you guys to do a "take-over" screen session to install/uninstall and self-troubleshooting, the only problem I concluded lies with your software. After I uninstall AVG, my internet works perfectly and it is faster!! So what kind of software are you selling to your market, and where's the QC and beta testing?! After so many years of using AVG, I am jumping ship!!! You can't even address the problem correctly. So many unhappy customers are complaining in this thread for almost a year, and no concrete solution and/or update have been adrdressed by AVG, SHAME ON YOU! Am asking for refund NOW!

I have had 2 remote sessions with your technicians, with a complete uninstall/re-install of AVG. This still has NOT resolved my problem with Wifi connectivity. As soon as I disable AVG, wifi is fine. Activate = no Wifi. This has been an immeasurable waste of time. I have been a faithful customer of AVG for many years, however you're losing me for a better 'bugfree' product. AVG needs to resolve these issues prior to implementing into the retail world.
