How to REMOVE spyarsenal.com from my computer.....?

i'm not sure, but i think spyarsenal was downloaded and or used on my computer, and i need a good free site to get RID if this program. i'm currently using 'spyware terminator' i'm really hoping it works, i also read up about it and it has good reviews. I need to get rid of Keyloggers spyware so can anyone recommend any good FREE site? thanks
