Here’s what happened: I worked with this partner program for quite a while, but then I received a complaint about my website claiming that I was spreading viruses. After discussing everything with Yandex, I managed to remove the warning. Later, I confirmed Yandex's concerns about the harmfulness of the files from "file-space dot org." You can find all the details with screenshots at the link >>> http://gold-mine.io.ua/s940735/file-space.org_raznosit_virusy. Stay away from them and don't get involved if you care about your websites and PCs.
