Nuke Modified | AntiVirus Remover

Can anyone recommend a good virus removal program?

I know Ive got a virus, according to malwarebytes its “Adware.Ecobar”. Its been shutting down and freezing my computer alot and Im sick of it. I been using malwarebytes & AVG and neither seems to block or remove it. Any suggestions?
Thanks to everyone who responded. I decided to try the Superantispyware. Its the free one but it did find alot of crap that avg and malbytes did. 2 Questions…..1. You think I should keep the avg and malwarebytes? 2. Is it really worth getting the paid version of Superantispyware? Thanks again
I meant its the free version but it did find alot of crap avg and malware Didnt find. Sorry
