[2022 - Found myself without a keyboard or mouse after install...]

I found myself without a working keyboard or mouse after installing Kaspersky Free. LUCKILY, the mouse worked when I unplugged it since it's wired and wireless.

I scoured the internet for a solution to my problem and quickly learned that has been an issue with Kaspersky since as early as 2016!?

I saw that while keyboard input seemed, blocked, I was still able to communicate between PC and keyboard adjusting volume and opening calculator, for example. Moving forward, I tried uninstalling the devices multiple times and reinstalling them (after system restart), I tried modifying the registry, I tried running several different scans...  ZERO luck. Then I thought, "Maybe disable Kaspersky?" Still nothing. I uninstalled, restarted, nothing. Windows troubleshoot was unable to fix my "driver error".

I caved and called Kaspersky - this seemed promising since the rep sounded friendly! Alas, they told me the problem was not due to Kaspersky (I KNOW it was since that was the only significant change I made to my system), they could not help me and that I might need to contact Microsoft (ROFL, no)...

Solution: Hold the shift key and restart the PC. Select a restore point from before installing Kaspersky. Wait about 10 minutes (will vary by system).

Thanks for nothing, rep! ZERO effort. I hope you are shown this and not reprimanded, but at least LEARN to apply yourself to help customers. Call Ref #: 14316475

I have the same case, after installing Kaspersky then my PC restarts and after restarting, the keyboard and mouse can't be used.  I hope someone has a solution for this problem.  and one more thing I can't do anything on windows because the keyboard and mouse don't work

Just wanted to add that I have this same problem now.

I uninstalled Avast, installed Kaspersky, used my PC for a couple hours, restarted and now mouse has a "driver error" and keyboard has a "driver error" that windows troubleshoot cannot resolve.
