So if you are having similar stutter issues with your Bluetooth mouse and your sensor is further than 20' I would give this a try, especially if you are like me and tried every single other solution out there in the forums. All I know is I moved the sensor from about 40' to within 20' and its been smooth sailing. I don't know why or how a new operating system could lower the Bluetooth connection signal between two devices or whats going on. It's been 2 months and THE MOUSE HASN'T STUDDER SINCE!! I can not explain it. I hooked up the Bluetooth sensor wire extension that came with the mouse and I mounted it under my monitor so that the mouse is never more than 20 inches away from the sensor. For some reason I thought perhaps it had something to do with the proximity of the mouse to the Bluetooth sensor. It wasn't Avast as it started to stutter again. If you have a wireless mouse, try to connect the USB receiver to a different port. If your mouse is not working, follow these instructions: Reconnect the mouse. Wait for the computer to restart and open Windows.

UPDATE****** 12/26/15********************** I found a permanent fix for the mouse stutter in my case. Right-click Start (), select Shut down or sign out, then select Restart.

I wonder if that has something to do with the problem. Is there a 64 bit version of Avast because my version is 32 bit running on a 64 bit system. It must be Avast's background monitoring that causes it. Fixed, I put Avast in gaming mode and it hasn't done it since.
