Everytime I press the SPACEBAR button, the on-screen pointer/arrow thingy moves in a "North East" direction on the screen. It is very annoying. The pointer/arrow thingy sort of glides, and while it is "gliding", the pointer/arrow cannot be moved in any way at all.
Could this be malware/virus/or something like that?
Please help me, and I would just like to say that I am not very good with computers, so can anyone please give me a step by step tutorial on how to solve this problem?
