Hey ppl - Ok, I got on my PC this morning and everything seems normal, accept the fact that my mouse keeps freezing

The PC don't freeze (I can still ALT + TAB, type, etc) - it's just my mouse.
Do you know if there's a virus that would do this, or am I going to have to spend some more money to replace my expensive mouse?
It's a Logitech MX500 wired optical mouse, btw. Picture for effect
