Keyboard Only Typing Numbers In Sequence - Num Lock Off

When in word documents or typing in browsers, my laptop keyboard is perfectly fine, but when I'm in a game or certain other programs (like typing in Pandora, the internet radio) my keyboard (all the numbers, letters, and punctuation keys), when hit, will display numbers. No matter what key is pressed the first press gives me a "1," the next a "2," and so forth until "0" which is when it goes back to "1." I can't play anything and have to copy paste into Pandora's typing field.

Oddly, when I hit CTRL-V to paste it still registers. CTRL-random number would not paste, so something is (I think) changing my letters into numbers after the letter registers. I tried to do all the Num-lock and scroll-lock stuff but it didn't work. AVG Free's scheduled scan turned up nothing. I'm currently scanning with Malwarebytes Anti-Malware and Spybot S&D. Unhackme says there is no Trojan on my computer. I temporarily fixed the problem previously with a system restore, but it did not last.
