Ah ok i might have changed that, i will try that

Is that the tuneup software from 2345? 2345 PCsafe? If so seems to work fine but not easy to test since i have no idea what it sais and have to gues what it does =D

Well thats the only one i figured out how to download =D

Hi dmitriy,

The initial test looks very good, no unexpected reboot while using the safe browser(Firefox) for around 2h with hardware virtualisation enabled, which far exceeds the usual timeframes. 

From my point you can put the bug on probably fixed, i will continue testing to be sure and report back around next week, if thats ok with you guys at Kaspersky!?

Hi dmitriy,

I think this is the dump from using chrome, its very different there. It seems i only had to open paypal login and type something in, then i get an unhandled exception in plugin-nms.exe and a while later the dump.

A key part for the dump seem to be one or more of the plugins, but i havent had the time to figure out which.

Traces +  dump: https://cloud.qainfo.ru/s/BM9nFOcDl6sqdAt

As far as i can tell, something goes wrong in combination with those plugins when i go on the paypal login page, which results in the dump in the end. Should be the same for Firefox.

@dmitriy-pisarets

1) Still working on it.

2) Dark Reader, Decentraleyes, HTTPS Everywhere, Privacy Badger, Ublock Origin, Kaspersky Password Manager, Kaspersky Protection

Reproduction Steps:

1. open the paypal login page with a link like : https://www.paypal.com/de/signin/
2. turn off the option to save settings for this site and open website in safe browser
3. type in a username and password (first signs of problems start here its usualy laggy the typing in of the password)
4. close safe browser
5. refresh the page where you were asked if you want to open the site in safe browser
6. turn off the option to save settings for this site and open website in normal browser
7. type in your info, click something on the site, logging in not required ( the dump should be created now during this step)

With those steps its stable to reproduce for me.

@dmitriy-pisarets

Turned on traces,

used the computer for about 20 min

started safe browser (Firefox)

10 sec later i had an unexpected reboot

As far as i can tell the new driver improves the stability a little but still has reproducable unexpected reboots.

@dmitriy-pisarets

A quick test showed no unexpected reboot within the usual timeframe, so i think youre correct and the problem is solved.

But i dont have this option in registry so i used the gui.

I will continue testing.

EDIT: just had another unexptected reboot so not fixed as far as i can tell.

I will test with the new beta version see how it is going there.
