Redirect from google search results page in chrome, hmm?

Question

Google

For the last week, Google Chrome, from the search results page, automatically redirects to various sites that are not related to the query topic :)
What kind of virus is this, what exactly is it from the Google query page, 1-2 times a day, only to fairly well-known sites are usually in the area of ​​selling things.
My bitdefender does not see anything, ran the system with several utilities, such as malwarebytes, dr.web, kasperom, and others, but still did not find anything.
The only thing that I installed in recent times, before what happened, was tanks, from vg.
My account has more than once become one of those on whom experiments are being carried out, people from Google, so maybe this is it? Absurd, but still.

Answer 1

See browser extensions and router settings first. And then - to Bitdefender for support if it doesn't help.

Answer 2

There was something similar after the girl decided to download plugins for Lightroom on my laptop.
The software was called something like DNS Unlocker. I didn’t let myself be removed calmly, anti-malware helped. See if you have the same?
Well, or watch browser extensions, plugins, unfamiliar processes in the OS and run the system for malware.
