Need help to kill Google redirect virus

I have no idea how I got infected this virus. but it's really difficult to remove.

I scan with malwarebytes, eset nod 32.

But can't remove it.

It must be that yesterday my friend visit me, and he watch porn. I did not notice any problem since today, I search with google, I was redirected to happili.com. the search result is not what I want.

I need help to know how can I get rid of this annoying virus.
