Hi Everybody thanks for the immediate responses.
I am with Hostgator have had a few problems before and told Hostgator who just told me it was because the wordpress software is not up to date. I do not accept this but have updated everything. I also had an “expert” look at this and give up.
However I was able to (a certain extent) access the site I now can’t strangely enough Hostgator just told me they logged in without any problem so I send them a video of my login and showed them the redirect to an .ru site as above.
I’ll keep you posted but my feeling is I need to crash the site and build a new one as this is ongoing.
