replace mouse?

if you have an extra mouse you may try to switch it to see if the mouse its the problem. If it isn't then yeah, its gotta be a virus or something.

over sensitive mouse button?
may have broke... it shake it a bit and if it clicks, that is it :3

Try reinstalling the drivers

Once my mouse stopped working at all so I did that and it is fine

Actually... is the computer a laptop? Sometimes the touchpad and the mouse argue...

Or if the mouse is wireless, sometimes local interference causes the clicks...

The way to handle both issues, is to fully shut down (not just restart) the computer, wait about 30 seconds, then start it back up.

The reason for the wait is to clear the RAM entirely, but anyway, when the computer restarts, whatever issue was there is typically wiped from memory, and also, wireless mice channels will reset. Probably will be a little quicker to at least start with just a restart like this.

mine's a personal computer. D:

it seems to be working okay now but I'll do that if it screws up again! thanks☆

I sometimes have to clean my mouse wheel. It does stuff like this.

ah
Mine's lazers though :<

Mine is too, but the wheel sits on top and is made of rubber x3

oh wait lmao

i thought you meant the mouseball. LULZ

Mine did it without even touching anything, so I was sure it was the mouse-to-computer thing if it wasn't a virus

Never even heard of a virus like that. And really cant think of a reason why someone would write one like it. Cause they would have to target each manufacturers software one by one and the default controllers of each computer manufacturer in order to effectively attack mouse function on all computers. Cause each mouse manufacturer, logitech, microsuck, etc., have their own software, and its different stuff.

On top of all that, whats the motive? Other than to be a colossal pain in the ass their isnt any secure content that they can get a hold of by interfering with your mouse. Most viruses are attempts to access secure areas of your computer, spread other viruses, sell you some thing, or forcibly advertise something.
