After the update, the PC will not recognize my mouse

Never thought in life because my Kaspersky times the "new" PC paralyzes!
The update has not worked out the same, so Kaspersky has installation undone. After that I did a reinstall done where I was on the Internet. Previously this was not the case. Then the installation went well. After rebooting my mouse was no longer recognized. After I've googled the problem on a different computer, I realized that this problem mouse (+ keyboard) are no longer recognized very often happens.

This error could despite several hours of searching and trying not to be resolved by me.

I have Kaspersky installed previously on a different PC, during the installation, I was from the start in net. Everything worked fine, but since the computer is very laaaaaaangsam!

Hopefully can help me a computer expert. Let's see what the "fun" is costing me.

Addendum:
The fun has cost me 15. The problem was the engineer well known. From time to time it happens that after installing Kaspersky mouse, the keyboard, or both are no longer recognized by the operating system. Kaspersky blocks the USB driver.

Solution: Uninstall Kaspersky was a program (from the Kaspersky website). After the mouse has been detected again. If the mouse and keyboard are not recognized, then a new operating system has to be raufgespielt.

That is an impertinence Kaspersky This problem has been known for years and yet produces nothing has done it!

For me, Kaspersky has done something of !!!

I was advised to use the free antivirus from Microsoft ...
