Is my optical mouse possibly dying?

[Statyk]

I've had a malfunctioning mouse for nearly a month now as well. After updating software and hardware drivers, as well as scanning for virus/malware, I just tried a new mouse I had laying around and I haven't had a single problem in over a week with it now.

I had a RAT7 and it seems to have died after a little over a year of use. So I'd suggest finding a second-hand mouse and giving it a run for awhile, see if the problem occurs still.

May I ask what mouse you have is? I'm looking for a replacement and want to make sure I don't get any possibly risky ones.
