BSOD STOP D1 - pci.sys

My Apologies for the long silence.
Life got busy and I have been having problems with Kaspersky auto-updating itself to the latest version (a la Microsoft's Win10 auto-update), destroying my system functionality.
I have to find a way to block this, but the last try did not work.
I will probably switch to BitDefender, when stable.
When a software company gets this arrogant, it is time to look elsewhere.
KIS has been good, but they keep removing useful functionality in new versions, and now this forced auto-update is a step too far.

I have run one Driver Verifier and to save time, I restricted it to run only on pci.sys.
As expected, it died with an E6. This sort of stopped me in my tracks.
The E6 Dump can be provided, if required.
I haven't yet quite figured out how to run Driver Verifier on ALL drivers EXCEPT pci.sys, to verify the other drivers, without having to individually tick all drivers.
To be honest, I sort of lost interest at this point, not knowing what to do next, and put it in the "Too hard" basket for the moment, hence the silence.

This is the BSOD E6 Driver Verifier Dump, dated 26/Feb/21.


It would be much appreciated if you can gather more info from it.

Thanks Wither 2.

As an ex-Analyst/Programmer, I am guessing that this file "klkbdfit.sys" belongs to Kaspersky, the KL being for Kaspersky Labs & the kbd being for keyboard.
Kaspersky Internet Security (KIS) has an on-screen keyboard, for data input protection & I am guessing that this file is something to do with that, although how exactly, I do not know.

Unfortunately, I got warned of a Trojan by Malwarebytes at that URL.
I will look for more information elsewhere.

An update.


Apparently, "KLKBDFLT" is a Kaspersky Labs Keyboard Device Filter Driver.
I am not really sure how that helps me though.
If it was ONLY needed for the Online Keyboard, I might be able to block it or something.
Maybe updating this file would help.
I will attempt to do that.
