After switching from win to linux, and observing chrome process background behaviour for a while now I can with great certainity say it resembles a malware...

Haha, I've avoided Chrome for years now because that's a concern I have! Next to that, I wouldn't use a browser developed by the biggest (one of) data slurping/privacy invading company in the world.
Adding to that that it contains proprietary code == fuck this shit I'm out!

What makes you say that?
