Right-click menu repeatedly appears w/o my actually right-clicking

[student]

For a few weeks now my computer thinks that I am right clicking
repeatedly and the right-click menu continues to pop up when I have not
right-clicked. No matter what program I am running the problem still
arises. At times I cannot even type in my passwords without having to
left-click off of the menu a billion times. I have tried reinstalling
the touchpad drivers for the dell laptop and also I have tried system
restore. I have called dell and was walked through the driver
reinstallation process, however the problem still remains. I have
scanned my computer in its entirety for viruses with new virus
definitions; none were found. This happened about a year and a half
ago, but went away. I am not sure why it has returned nor what to do
about it. I cannot use my computer at times. PLEASE HELP I NEED MY
COMPUTER.

Clean your keyboard. There is a context menu key next to winkey on RHS.

I tried cleaning the keyboard, thinking that there was a problem there,
but the menu still comes up. It comes up even when I am not actually
using the keyboard or mouse, for instance if I am watching a DVD.
