Hello again,

Unfortunately the console doesn't show anything most of the time even when it freezes/hangs.
I've attached a screenshot of the console when trying to access www.youtube.com if it helps.

Thanks, Elliot.

I also have the same problem. Chrome unable to open any website, Opera is working but slowly. I disabled  QUIC/HTTP3 scanning in webshield as suggested in this topic and its back to normal.

Hi all, we working on fix, but we need logs from chrome when problems happen.

1) Enable QUIC/HTTP3 scanning in Avast
2) Close all chrome windows
3) Open command line - press Windows+r, type cmd and press enter
4) Copy this command to command line and press enter.
Code: [Select]
"c:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --incognito --enable-logging --v=1 --log-net-log=%userprofile%\chrome-log_%random%.json https://www.youtube.com
It opens chrome in incognito mode and loads youtube.
5) Close chrome and copy console output to file.
6) Find all chrome-log_XXXX.json in your home directory and share it (with console output) to us via google drive - send me message with link, or send it to us according to https://support.avast.com/en-ww/article/160 - send me message with archive name.
7) Disable QUIC/HTTP3 scanning in Avast

If problem did not happen, try different website in command, or remove --incognito parameter.


Thank you in advance for cooperation.

I am having the same issue with every website I try to open. I have identified the VPN I purchased and installed last night. When the VPN is one, it takes like 15 seconds to load any page, and the same amount of time to change pages or follow links. With the VPN off, all is good again.

I am requesting a refund for the VPN. I cannot figure it out, and no one else seem to know anything. It's doing it on mine and my wifes phones as well.

Reported to Avast. Let's see if that helps.

Avast Free/20.10.2442 AND 21.1.2449/Win7 machine

This is still a major problem.

Nearly every website loads (or begins to load) then freezes/sputters within 2 seconds. After about 5 seconds the site seems usable in terms of images, links, etc.

I began experiencing issues with Google Chrome after the December update. For about a month I assumed it was something on Chrome's end, but the next Chrome update didn't help the freezing/lagging issues. I checked the forums and found this thread. I disabled QUIC/HTTP3 scanning, which improved performance but it's still not at "normal" speed.

Recently it's seemed to creep into Firefox as well. I don't want to disable anymore features, and I don't want to switch AV as I've been using Avast for well over a decade.

I don't understand. We got an update on the program today, yet Webshield making browsers hang (both Edge and Chrome in my case) is still not fixed. After three months?
