Plagued by some kind of browser adware

[RaZoR1394]

Since a few days ago I am randomly getting annoying popups like casino sites when using Google Chrome. Some url's also seem hijacked. For a while I had tried reaching some of my favourite sites but I was directed to spam sites. I can't pinpoint the cause. I have removed almost all my Chrome extensions but the problem persists. I had the url hijack problem with Chrome on my android phone as well. I can use Chrome for several hours without problem then suddenly it starts throwing me a lot of spam popups and It's very annoying. I have never seen such a behaviour in a GNU/Linux environment before.

I am using an updated 64bit Ubuntu 16.04 installation with the latest Google Chrome.
