I’m running the most recent version of windows 7 64 Bit Home and downloaded the latest update to Avast Free last night (9/20/2019). After the update finished and I rebooted, I was unable to open Firefox 64 bit, the latest version of Chrome and the latest version of Thunderbird. It only seemed to effect these 3 programs. I uninstalled a bunch of updates to windows, other programs nothing worked. When I uninstalled Avast it fixed the problem, standard uninstall - not safe mode with Avast Clear program. Reinstalled Avast, same problem. Uninstalled in Safe Mode with the Avast Clear, then reinstalled. Same problem. Before I switch to another Free Antivirus, was hoping to fix the problem and re-install Avast.
No other AVs were ever installed. This was a clean install in 2009 with a new system and have been updating Avast ever since. The only “security software” on this computer is Spybot 1.62 and CCleaner 5.61.7392. I DON’T even have the MS Security Essentials. Again the only thing that solves the problem is uninstalling Avast…
Thanks. So what should I do. I have chrome open so I can respond here, but the link in the diagnostic tool that opens a Chrome (default browser) window gave me the same error. Should I just leave my computer on as-is until I get a response? Or will it hurt the process if I uninstall Avast again?
Hi deeverett,
If you see the error message box it means firefox crashed can you please try to take a look for *.dmp files ?
Firefox dumps should be stored in %userprofile%\AppData\Roaming\Mozilla\Firefox\Crash Reports\pending folder.
Chrome dumps should be stored in %userprofile%\AppData\Local\Google\Chrome\User Data\Crashpad\reports.
I havent found any error record about firefox in event logs but there are 2 error :
Activation context generation failed for “C:\Program Files (x86)\Adobe\Acrobat 9.0\Designer 8.2\FormDesigner.exe”.Error in manifest or policy file “” on line . Application configuration specified an invalid private-assembly probing path. The invalid probing path was part of C:\Windows\WinSxS\manifests\amd64_microsoft.windows.common-controls_6595b64144ccf1df_6.0.7601.24483_none_e372d88f30fbb845.manifest.
A fatal alert was received from the remote endpoint. The TLS protocol defined fatal alert code is 40.
Ich hatte das gleiche Problem am Wochenende. Browsers Chrome, Firefox und Opera gaben diese ehlermeldung. Thunderbird ebenfalls. Ich habe alles versucht um diese Programme wieder flott zu bekommen. Vonj Hardware bis zu Sofwareproblemen (Registry usw.) Nichts half ausser das komplette enfernen von Avast. Ich hoffe es gibt bald eine Lösung für das Problem da ich ungermne auf ein anderes Programm umsteigen möchte.
well if you like I can post in English too. I thought because the thread was in German I post in German. I did have the same problem this weekend. Browsers Chrome, Opera and Firefox did not start any more. Thunderbird did not start either. I looked at all possibilities in Hardware (RAM etc.) and Software (Registry etc.) but only a complete de-installation of Avast helped to solve the problem. I hope you will have a solution soon because I would not like to use a different antivirus software after using Avast for many years.
the newest crash files in both Chrome and Firefox were from 2017, the issue is NOT the apps crashing, it’s that they won’t load - hence the picture of the error message I posted to start this thread.
To get back to this page and click on the links, I had to uninstall Avast AGAIN! If we can’t solve this problem within the next few hours, I’ll have to switch virus software. This is my 76 year old Dad’s computer, and he isn’t capable of troubleshooting. I’ll be away from his computer for the next few weeks traveling, and I don’t trust not having AV software on his computer…
Hi deeverett
firefox, chrome and thunderbird exited with status code 0xC0000005 -access violation but none of them created a dump file :-(.
Can you try to run thunderbird or chrome under debugger to capture a dump file.
Just download procdump tool from https://docs.microsoft.com/en-us/sysinternals/downloads/procdump
And start chrome from cmd line :
procdump.exe -accepteual -e -l -x c:\dump “C:\Program Files (x86)\Google\Chrome\Application\chrome.exe”
-x c:\dump - path where you want to store dumps - change it to your existing folder !!!
Similar cmd line for thunderbird:
procdump.exe -accepteual -e -l -x c:\dump “C:\Program Files (x86)\Mozilla Thunderbird\thunderbird.exe”
I dont know if we will be able to fix the issue within few hours but any dump would help us fix this issues for other users !
My story: I live in Spain. My computer has Windows 7 and it had AVG Antivirus Free intalled. Last September 21st, AVG Antivirus got an update and, from that moment I couldn’t get to open Firefox Browser. The program didn’t even showed up, I only got the error message (0xc0000005) as deeverett said, but of course in Spanish. I unistalled Firefox and reinstalled it again, but the problem persited. So I downloaded and installed Google Chrome browser. Same as Firefox. It was downloaded and apparently installed without problem, but I couldn’t open it. Exactly the same error message as Firefox.
After that I unistalled AVG Antivirus Free. And then both Firefox and Chrome opened and worked fine. No problems. I downloaded and intalled Avast Antivirus Free, and again, I wasn’t able to open Firefox and Chrome. Exactly the same problem and error message.
Luckily I could do all that because I had MSN Explorer browser installed, and the problem didn’t affect it. Explorer works fine with the new Avast/AVG Free Antivirus update. Your Avast browser is also working fine with Avast. I’m writing from there. Now I don’t have AVG intalled.
I had been a user of Avast antivirus in my previous computer and was happy about it. But when I inherited my “new” computer it already had AVG Antivirus free installed, so I kept using that one. I’d like to keep both Avast and Firefox, so I would be very grateful if you could do something to fix that problem in the antivirus.
Finally, I don’t know much about computers, but I managed to check the crash report folder of Firefox to look for any dump files. As deveerett said, no files in there.
Sorry, if all this information is not useful to you. Just wanted to help
