Who do you host with? Most hosts that have tech support will be glad to assist you.
I went through something similar, contacted HostGator and they fixed me right up. That is what they are there for. This, in my opinion, is a lot safer.
My host doesn't do it, which is why I need someone to help me. Someone who knows how to get rid of not just the virus, but also delete whatever bug allows them to log into my account.
