System hangs and cavwp.exe crashes when I try to open https://pclab.pl with Firefox browser.
Important note: I’ve already described my issues in Bug Reports section on the forum - https://forums.comodo.com/bug-reports-cis/cis-causing-winows-10-to-hang-cavwpexe-0xc0000409-exception-t124511.0.html
At that time i didn’t know what was the reason. I was able to pin it to Firefox and pclab.pl and Mathi R suggested me to create new topic using required format. If needed I can edit old thread.
A. THE BUG/ISSUE (Varies from issue to issue)
Can you reproduce the problem & if so how reliably?:
It happens ALWAYS after restarting/starting the PC and every few hours while PC is running. Right after first hang/crash I can visit pclab.pl without any problems. After not using the PC for a few hours it will crash again (not using sleep or hibernate, just turning the monitor off).
If you can, exact steps to reproduce. If not, exactly what you did & what happened:
1:Start PC
2:Open Firefox
3:Enter https://pclab.pl/
4.System hangs, cavwp.exe crashes (exception code 0xc0000409)
One or two sentences explaining what actually happened:
System hangs for a few minutes and cavwp.exe crashes while Firefox is trying to load pclab.pl. Most of the page is loaded, but not 100%.
One or two sentences explaining what you expected to happen:
I expect pclab.pl to load without my AV crashing and system not responding for a few minutes.
If a software compatibility problem have you tried the advice to make programs work with CIS?:
Didn’t find any possible help regarding the issue.
Any software except CIS/OS involved? If so - name, & exact version:
Firefox beta 69.0b7, also occurs on latest stable Firefox.
Any other information, eg your guess at the cause, how you tried to fix it etc:
- it happens only on Firefox (though I’ve also tried Chrome Beta only - no problems at all)
- turning on or off AdGuard doesn’t make any difference, cavwp.exe is still crashing
- if i disable CIS completly, pclab will load without any problems. As soon as I enable antivirus module, cavwp.exe crashes when loading pclab.pl
- windows explorer isn’t hanging. I’m able to open start menu and click on some apps, but all of them open at once after few minutes.
- after few minutes everything goes back to normal
Also I didn’t find any files in:
%USERPROFILE%\AppData\Local\Microsoft\Windows\WER\ReportArchive
%USERPROFILE%\AppData\Local\Microsoft\Windows\WER\ReportQueue
but there are some folders regarding cavwp.exe in:
C:\ProgramData\Microsoft\Windows\WER\ReportArchive
