Seems that all so Chrome-Users (and maybe all KIS 2018 Users) are affected:

NkRQkYLz Thank you for reply , I have removed Kaspersky Antivirus and install DR.WEB instead hope it private blue screens in the future.

As a workaround, I think we should use an alternate browser until Firefox and/or Kaspersky resolves this issue.

just download and install Firefox 56.0.2 This is the latest version that works fine without causing a blue screen. You must only disable updates.
I will wait for a new firefox update until this issue is solved.

In the official Kaspersky-Forum (german), the MOD tells us, that Kaspersky knows about the Bug and solve it in Version (e)...
But when this comes, nobody knows...:)

I will use Edge with UBlock-Origin until the Problem is fixed...

Guts,
The logs were in a foreign language and could not be scanned or troubleshooted.
Please change the default language to English and re-post the zip for troubleshooting.

Yes, I will report back whether it solves the problem. As for the auto-enabling of the add-on, go to Kaspersky settings -> Protection tab -> Web Anti-Virus -> Advanced Settings -> Uncheck "Automatically activate Kaspersky Protection extension in browsers"

just tested, doesn't work for me. still blue screen after few minutes using Firefox 57. I think the bug is in Firefox 57. Do not recognize a connection to Kaspersky

Just remove Kaspersky AV temporarily and see if the blue screens cease.

Since last weekend, I've been seeing the BSOD a couple of time per day on average with the same KMODE CLASSPNP.SYS error message.

I AM running Kaspersky, but I have an older version of Firefox (52.5.0 32 bit ESR). What I've noticed so far, is that if I don't use my VPN (WiTopia), I've not seen the BSOD. As of now, this is only anecdotal, so I'm wondering if anyone else is using the same or similar VPN as well?

Thanks, and I'll be "reading the mail".

No VPN here, BSOD only when using Firefox 57.x
