Q. regarding yahoo messenger spy monitor software!

Hello everyone, I am new to this site so didn't know if I should post this question at this forum or somewhere else. But I am in trouble somewat right now.

I downloaded Yahoo messenger spy monitor verison 6.9.0 yesterday just to see how it works. And then i deleted it from everywhere in my computer because I realized that software was little dangerous. Now the real problem is Yahoo messenger spy monitor notification bar isn't removed from my computer. and when i try to remove it, it says "the version that you are using is a trial version. you have to buy a product in order to remove this notification bar. I don't want to buy this product. I want to remove this notification bar anyhow. I have scanned my pc like 4-5 times using McAfree, Windows live onecare, Noadware and SuperAntiSpiware. The notification bar is still the same sticked up on the right top of my desktop screen. Any suggestion please???
Your any help will be appreciated!
thanks!!!:cry:cry:cry

 

Thank you so much for ur help, I scanned my computer again like 4 times and that notification bar has been removed...
