When you uninstalled, did you use the removal tool? https://download.avastbrowser.com/avast_secure_browser_uninstall.exe

Hi. Same problem.

I went out for an Eastern vacations and when I returned I couldn't see anything in the Secure Browser but the minimize, maximize and close buttons. I installed the latest version available but nothing changed. I have a Compaq 610, Windows 7 Home Premimum.

Thanks in advance.

It's been reported to Avast. This is also the weekend and Easter weekend at that.
Don't expect an immediate reply. Enjoy Easter.

Hello.
The same issue with 2 PCs (both win7 x64). After last Avast Secure browser update cannot launch browser- it hangs up with up to 100% CPU usage. Reinstall does not help. The only way is run browser in compatibility mode (winXP SP2 or 3) or switch to another browser.

Hello,

thanks for reporting the issue. We have already started investigation. Let me summarize what we know about the problem:

- it occurs on Win 7 and Win 8 OS's
- only some users are affected
- browser latest version 73.0
- browser is frozen, no tabs, it is not possible to do anything in it
- in event log there are errors related to Avast Secure Browser Elevation Service
- uninstallation and clean installation does not resolve the issue
- did I miss anything?

We have to find what is unique on affected machines. Please can you help us with investigation?


1) Create dump of the browser process
1 - Run browser
2 - Open Task Manager (right click the windows taskbar -> Start Task Manager)
3 - Search for AvastBrowser.exe (how many processes do you see?)
4 - Right-click the processes and choose "Create Dump File"
5 - Pack all dump files and send it to us (you can attach it to your post)


2) Enable browser debug logging
1 - Open command-line window, locate AvastBrowser.exe file (it is usually in: c:\Program Files (x86)\AVAST Software\Browser\Application\)
2 - Run "AvastBrowser.exe  --enable-logging --v=2"
3 - Close the browser
4 - Go to c:\Users\%USERNAME%\AppData\Local\AVAST Software\Browser\User Data\ and send us safer_debug.log file


3) Will clean profile help to resolve the problem?

Steps:
1 - Close the browser
2 - Disable Avast Self-Defence in AntiVirus Settings -> Troubleshooting page
3 - Rename the `c:\Users\%USERNAME%\AppData\Local\AVAST Software\Browser\User Data\` folder to `c:\Users\%USERNAME%\AppData\Local\AVAST Software\Browser\User Data_BAC\`
4 - Launch the browser - is browser working?

4) Send us user_id

1 - Open Regedit and go to: Computer\HKEY_CURRENT_USER\Software\Avast Software\Browser
2 - send us user_id value data


Thank you very much!

I am running Win 7 and I don't get the blank screen and frozen browser.  I am able to use the browser just fine.  The problem I get is the System log has the Elevation Service error.  The error seems to indicate that the service is looking for a file that does not exist.

Hi,
I've followed your instructions and got the debug, Id and dump files. How can I send them to you?, since only the debug file is bigger than what is allowed to be attached to the post.
Instruction 3 didn't help. Thanks a lot.

Avast ftp server where you can upload dump files and logs.
https://support.avast.com/en-ww/article/160/
Zip the file give it name you'll remember and post that Name here.

Hi Ondrejz, thanks for the help.

The files are here: https://ufile.io/xcjieioe

Thanks again.

For those, who can reproduce the problem:

Did you try to rename the profile? Did it help? If not please try this:

1) Move the "Extensions" folder to other place so it is not present on this location:
c:\Users\%USERNAME%\AppData\Local\AVAST Software\Browser\User Data\Default\Extensions

2) Run browser. If the problem persists, move the folder back

Do not forget to disable Avast Self-Defence in AV settings before, thanks!

Apparently this type pf problem has also been reported for the Chrome Browser.
On of the suggestions was to disable Hardware acceleration under the extended settings in the System section.
I've never seen the problem in Chrome but I've also always had hardware acceleration turned off to help speed up the browser.

You are right, this setting is related..

For those who are affected, you can try avoid the problem running the browser in compatibility mode and then disable the setting in the browser. From that time, you can run browser normally.
