Hacked website?

[calaf6 +]

Don't know if anyone here can help or shed light on this one, its nothing to do with 68, but with the amount of knowledge here its a good place to ask.

I am having problems accessing one of my websites cpanel. I changed the password on Monday as it was not recognising the one I had. Today the new password did not work, so I changed it again and while I was in cpanel I started to get a server not found error message.

At the weekend I also discovered that I had a virus on the site, not sure if its related, but I am suspicious about it all now.

So, any ideas if I could have had some software planted that picks up password changes, and if so hoe do I trace it, remove it, and find the ip of the originator so I can ban them. I am in contact with the service provider, but they are not over fast with responses
