A virus that redirects to another site from search engines - how to get rid of it?

Question

Joomla

Broke the site on Joomla (1.5) When you try to go to the request from the search engine, there is a redirect to the "laying" of the casino. Where to dig?

Answer 1

There was already a similar question - What kind of antivirus to treat the site?
For starters, I really recommend contacting your hoster if you are new to this.
