I just installed Kaspersky free AV, downloaded through your website (startup_14441.exe) an hour ago and it destroyed my laptop, latest Windows 10 64bit, default AV Windows 10 Defender + Malwarebytes free (manual mode scan). There is no malware on the laptop, I do daily scans with both Defender and Malwarebytes.
The installation of your AV went through fine it seems, it asked me if I want to activate KSN, I said no. It then installed and then there was a popup asking me two things I dont remember, I think if I want the AV to auto remove known malware like dialers and such, and another question. I wanted to click ok/next, but nothing happened anymore. The dialog was frozen.
I clicked start menu button, the animation of the button went down, but no start menu appeared. I had Chrome open in the background, and it had asked me to activate the Kaspersky addon, Chrome was still responding at this moment. I clicked yes enable, and at this time Chrome stopped responding too. More and more parts of the OS seemed to freeze/ crash every second. I tried ctrl+alt+del but no reaction. There was still animation going on on the start menu, I could still move the mouse cursor, I could still type with my bluetooth keyboard, but the entire OS seems to be freezing.
After about 1 minute or so, I got a bluescreen of DPC_WATCHDOG_TIMEOUT or something, system not responding anymore. PC restarted.
Restarted Windows, logged in, all seemed to work. I opened the Kaspersky systray icon to look through the settings, then maybe after 30 seconds of login, everything started to freeze again. After 1 minute or so, watchdog bluescreen and reboot.
Restarted Windows, logged in... same behavior. I am now stuck. Cant uninstall or do anything anymore, the PC is totally broken, because of your software. Tried to boot into safe mode, but pressing F8 during Windows boot manager doesnt do anything, it always boots into normal mode. Triggering safe mode out of Windows doesnt work obviously, because I have not enough time, the system starts to freeze after login maybe 20-30 seconds later.
