"Spyware Protect 2009" keeps popping up-how to uninstall it?

[Obscure]

My dad put it on my pc, but apparently it expired because it's saying I need to pay $50 to fix the problems that it's listing.

I tried going to the control panel and deleting it and looking it up on my start menu. The thing is driving me insane...I can't type this without it popping up four times.

Are there any free decent anti virus programs?

I would really appreciate it.
(And it won't let me exit it..just pops back up into the main program when I try to right click for the exit option)

First make sure you are the adminatrator. Then go to the control panel and find the program one that says install/ uninstall or install/remove.
Then click the ones you don't want but first click to remove it.

And a good protecter is NORTON SECURITY and SPYBOT DESTROYER
