My computer has a little problem?

[Kyle Vachon]

Recently, my computer has been randomly doing what I like to call "tabbing out", or exiting my current screen like you do when you press Alt+Tab. I don't really know what to call it.

For instance, when I'm browsing or on my browser and scrolling (like on facebook) with the arrow keys, the screen keys will suddenly not work and I have to click the browser again. Also, when I'm playing MMO's like Guild Wars and WoW, it keeps exiting to my desktop randomly without closing the client.

I don't know why this started happening. There was a period about a week ago where I didn't have virus protection for about an hour, and it only started after that. But I can't imagine I got a virus, since I didn't do anything while it was uninstalled.

It's a small problem, but a nuisance, especially when gaming. I've also tried a lot of things (such a system restore), but to no avail. If anyone could help me fix this, it'd be greatly appreciated. Thanks in advanced!

Sounds like a problem with your keyboard, if that helps at all. I mean like an actual physical problem and it is mistyping

Just get Avast Free Antivirus and run a full scan.
