I collected some max level traces hopes thats helps.

I started the trace collection, started the protected browser and reproduced the issue twice. Then stopped traces.

Traces: https://cloud.qainfo.ru/s/aBg6OdCdaNkuANg

Okay that seems to be stable way to reproduce it for me.

1. Open https://www.paypal.com/de/signin in the protected browser
2.  Open the virtual keyboard
3.  Spam with normal and virtual keyboard anything in the password field.
4. The windbg error pops up within 2-3min

Sorry to hear that, i sadly dont know either, what happened. If i encounter it again, i will report again, until then mark as unreproducabel.

Real PC:

Windows 10 x64 18362.356

KTS 21.0.20.748 app+drv ver. on

Standard browser: Firefox

Reproduction steps:

I was using the Protected browser(Firefox) for couple hours when i got this dump and the protected browser froze.

In taskmanager avpui.exe was listed as inactiv, i didnt have any access to the gui of kaspersky but could use anything else normaly.

To unfreeze the browser i had to kill the avp.exe process to reset kaspersky.

Apologies for the large trace file but i had planed this as a longterm protected browser test and didnt want to reset the traces files.

Real PC:

Windows 10 x64 18362.356

KTS 21.0.20.748 app+drv ver. on

Standard browser: Firefox

Reproduction steps:

i got this dump when i opened a website from a search result.

Version 20: Avast free gets detected but KIS and KAV install fine if i follow your step

                     AVG doesnt get detected as incompatible

Version 21: Avast and AVg dont get detected as incompatible.

No luck here...

EDIT: Tested on Vmware 15 with Windows 10 1903 up to date.

FAILURE_ID_HASH_STRING: um:application_fault_avrf_1cdaf4c6_app_control.dll!resetreferencecontrol

Reproduction steps:

Got this dump after i closed down the safe browsr(Firefox), i used it for around 2h, i also canceled a running rootkit scan but i think its related to closing the safe browser.

Real PC:

Windows 10 x64 18362.356

KTS 21.0.20.748 app+drv ver. on

Reproduction steps:

I was browsing 9gag.com while listening to music on youtube in the secure browser, also a rootkit scan started around that time. First i got the corrupted dump on 9gag, then 2 failed attempts to write a dump.

I tried to manualy create a dump, of the avp.exe process, when i got a driver_veriefier_violation BSOD, where of course was an error (according to  event logs) when windows tried to create the memory dump, so i dont have the dump there.

The dump from after the reboot i just reported before that.

I hope you find something in the traces but i will try to reproduce that whole thing.

Real PC:

Windows 10 x64 18362.356

KTS 21.0.20.748 app+drv ver. on

Reproduction steps:

I was doing some banking in the secured browser(Firefox) when the secure data input function/part crashed.

Windbg detected an error but due to the browser protection it wasnt able to read the memory and the virtual keyboard icon disappered, thats how i noticed.

It happened again later when i was just typing something on a website in the secure browser.

Traces attached, the problem should occure near the end of the traces.

I was restarting my computer to install KB4516115, KB4514359, KB4515348 and KB4512508 after the pc rebooted i had those dumps.
