Virus that works jumping from one letter to the next word while typing anything!!! ?

Question

Let say I'm typing this right now. Ok then while I'm typing this, suddenly the cursor goes back three words back, or deletes a few letters of the words! Anybody knows the name of this c**p!!! IS KILLING ME!!!

Answer 1

I think this is most probably due to virus. But get me an idea of ur s/m. Which mouse u r using(optical or normal scrolling)

Answer 2

If you're using a laptop, this could be a hyper-sensitive touchpad being triggered by a passing finger.

Hope that helps.
