My mouse double-clicks and the scroll wheel is busted, so i had to dig up a mouse that my dad bought like 6 months back. I plug it in and start fiddling with the buttons. It's a pretty fancy mouse, but all the buttons seem to do is make it glow a different color, so that's a shame. I click with it to see if it works. It doesn't, and not only that, it now quadruple-clicks.
I spent some time scanning my PC with an antivirus program, looking online for solutions etc. Then I try to press the button that has a 1 on it that turns the mouse red and that fixes it.

WHY IN THE FUCK WOULD YOU HAVE BUTTONS FOR MULTICLICKING ON YOUR FUCKING MOUSE?! THAT'S FUCKING RETARDED
