How do I fix this scrolling issue in my Logitech MX518 mouse?

My mouse was working fine for more than a year but suddenly scrolling started to behave weirdly. Scrolling seems to have its own life and has started to move up and down quickly making any computer activity impossible. Things I've tried include:

"The answer given about the lens and light sensor being dirty solved my wheel issue.

For me the wheel was very lagged and usually took a full spin just to get a single response or sometimes it wouldn't respond at all.

Open the mouse (three screws under the stickers, and after removing the top cover the wheel lifts up and out. Be sure the lens and sensor are clean (indicated by the red arrows in the image below) - in my case the sensor on the right side was dirty. The wheel now works like new again. I actually had to get used to how sensitive it's supposed to be."

"yes, it was I suppose at the optical reader of the wheel. Because I have shake it strongly and made a strong blow into the gap between wheel and mouse cover and suddenly the scrolling wheel works again..

I hope that will last a while otherwise I will be forced to open that which I want to avoid"

Clean it out. Take the three screws out under the stickers on the bottom. Slide the wheel and carrier out and remove all the built up dust and hair. When you remove the wheel you can easily loose the ratcheting lock but I prefer mine removed anyway. It speeds up scrolling.

"It was the SetPoint software for me. I uninstalled it and it works fine now. I also learned from the Logitech site, the following:

When you don't need SetPoint:

SetPoint is not required for the following mouse functions that are
built into Windows® 8:


Left click
Right click
Middle click*
Back/forward buttons for navigating Web pages
Scrolling**


* If you want to assign other functions to your mouse buttons, then
you can use SetPoint to change their functionality.

** Additionally, if your mouse has a tilt wheel, it will work in
most Windows 8 style applications, but you will need SetPoint if you
want to scroll horizontally in traditional Windows desktop
applications.

So if you don't need any added functionality, don't use SetPoint."
