How can I remove Personal Antivirus from my PC?

This Personal Antivirus which I accidentally downloaded is what I believe to be a malware or spyware something…

How will I remove this from my PC. I’ve tried system restore to an earlier time but after restoring it says “restoration incomplete”.
I’ve also tried downloading different spyware remover program but it is no use coz I have to register first the product (spyware remover that I’ve downloaded from internet). I have no credit card to purchase spyware remover.

Is there a free malware and spyware programs on the internet????? HELP>>>

you don’t really need an antispyware to remove personal antivirus. well if you get antispyware, it will be helpful in a future, but you can always find a free tool. anyways, there’s a way to delete personal antivirus manually: http://www.spywares-remove.com/how-to-remove-personal-antivirus
