I'm afraid my friend is like me and not very knowledgeable when it comes to webhosting etc. She says her webmaster is Vision ICT ltd. The hackers are from all over the world, and by all different people. My friend does not have anything to do with that side of the website, she is an administrator and pays the webmaster to sort out this type of problem, from your replies it would appear she is not being given value for money regarding service. Thank you everyone for all your help.
