Keyboard is whacked

My computer is a gateway running win  7 home.  I have this annoying problem that overtime I type in a search box of practically any kind it acts like the hotkeys or something is on.  For example, when I type a h my favorites windows opens.  Or if I type a b another search window opens. It won't happen 100% of the time but at least 45% of the time.  This is extremely annoying.  I'm ready to throw the comp out the door.

I checked my hotkeys and I don't have anything turned on so what is going on.  I've been told I may have a virus.  Can you have a virus on the keypad?   I run my virus protection often with Norton nothing come up, the comp appears clean.

 

Have any ideas?
