Recently, my computer has switched out of whatever program I was using to the desktop, and it usually types n/, /n, or /b. While I'm in BoutCheetah, it switches out to the desktop and opens up the start menu. It's been bugging me quite a bit, because I have done everything I could think of. Recently, I'd downloaded GameMaker Pro 8, SoundForge 10, Sound Wave Editor, and a couple other programs. I've uninstalled the majority of these programs, and nothing's working. It switches at random time intervals, so it doesn't always do something at a set time. I've considered the possibilities of a virus and/or a program checking automatically for updates, but Avast isn't picking up on any potential viruses; I've never had this problem in the past. Anyone have any ideas as to how to resolve this increasingly annoying problem?

I'm a baser, in case you couldn't tell from the name. Heard about the PS, came over checked it out, and here I am. In game name is QuickSpeed. Okiebye
