Adware / malware Removal Help ( wonderlandads )

I am running a mac osx elcapitan( 10.11.3)

Symptoms : popups in chrome redirecting to other site but first you see the link with wonderlandads.com/

I have run avast / avira and malwarebytes anti malware and they did not detect any infection.

I have cleared the history and cache in chrome and checked the extentions there are no suspicious extension(only last pass extension is there)

please help
