What is Biosc.xyz?

Biosc.xyz is a browser hijacker that attacks Mac computers and places its own search provider on the infected browser. Biosc.xyz app gets on users’ devices together with freeware or shareware as an optional component. Once it reaches browsers such as Safari, Chrome, or Firefox, a user will be forced to use the modified provider regardless of whether he or she wants it or not. The main problem here is that Biosc.xyz shows sponsored search results at the top instead of organic ones. Besides, you might start receiving intrusive commercial content such as various ads, coupons, banners, and deals during browsing activities.
