I my site has been hacked

Get a fresh cup of coffee, take a deep breath and carefully follow this guide. When you’re done, you may want to implement some (if not all) of the recommended security measures.

If you’re unable to clean your site(s) successfully, there are reputable organizations that can clean your sites for you. Sucuri and Wordfence are a couple.

Thanks Andrew

Using several of the online links you recommended to check if my site has been hacked, none revealed my site had been hacked.

What is happening is I am being re-directed to another site:

What can explain this?

I’m not sure I understand, I thought you said you were hacked. If you’re unsure ask your hosting providers.
