usb mouse using K4W-21-20\klmouflt.sys disconnecting and reconnecting with every fast movement of mouse

[Aleksandar2025]

Hello,

FPS games are completely unplayable. Every fast mouse movement is being stalled by that driver. How can I remove it and restore the default Windows one? I'm using windows 8.1, the certificate on that driver is for Windows 7.

Welcome to Kaspersky Community.

 

Both systems W7 and 8.1 are quite obsolete and out of support from Microsoft.

Thanks for the warm welcome and for getting back to me! The issue is resolved, it was a mouse cord issue, I've found the location and "patched" it up. I wrongly associated it with the antivirus, because the issue started back when I installed the antivirus, but it was actually my passionate movements of the mouse during online FPS sessions that caused the cord to become loose. I'm very much attached to my configuration and Win 8.1. Not just because it's the great OS, it isn't, Win 7 is way better, but it's what I have and can run on a 3rd gen i3 CPU and it runs good. Also lots of older games installed on it is what makes me want to stick with it forever, if possible. If you could please permit me to ask one unrelated question here. When is Kaspersky's antivirus going to stop working on my OS?

I don't know the answer, but for now:
