intelly-search.com and airsrch.co browser hijacker redirect the standard search (google) in all browsers

Question

No matter what I set the standard search option to, when I search in the adress field the two pages intelly-search.com and airsrch.co are visited and the results come from yahoo search.
first seen in google chrome, but firefox and Edge show the same behaviour.

It looks like seo has been installed together with libre office and since then the problem occurs.
