Keyboard problem or virus-infected pc?

This is my freaking third time typing again, so, I'll just tell everything in point form.

- 3 keys not functioning properly --%26gt; 's', 'w' and 'x' when typed, they give me junk, even open programs and search

- rebooted, didn't work, waited and tried again, failed

- checked out the following link --%26gt; http://answers.yahoo.com/question/index;...

- ran avast! antivirus [still running]

- thought a virus infection is a possibility since I remember seeing a dialogue box about taskmanager.exe not found or whatever

- hoping so badly that it's a keyboard problem and not an infection

What do you guys think? What should I do?

Any help rendered deeply appreciated.

Simple test, borrow another keyb or use that one on a diff PC, if prob follows keyb, buy new one, if another keyb does same, run FULL AV scan, and SPYWARE scan. Also try deleting keyboard from device manager and rebooting to refresh Keyb drivers in Windows

Sounds like a keyboard failure... especially as the 3 keys that have failed are physically next to each other.
