Periodic redirects to advertising pages ww9.domain.com hosted by X5X.RU?

Question

Network administration

Good night all.
Periodically there is a redirect to pages with advertising from a site hosted by x5x.ru
Even when index.html is removed and the root link of the domain is requested.
Tell me: who has come across a similar one, and if this cannot be fixed in any way, then where to "run" from this?
In advance, thank you all for your help.

check for viruses and you will feel better

Answer 2

Rub the name of the server. They are one of the old name servers proe...and that's why it's such a mess. If you rub it, the dns will be saved for a day and the problem will be eliminated. You rub both in the panel where you bought the domain, and in their hosting control panel.

Answer 3
