It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.

You are lacking some information:

  1. What changed on the machine in the past two days?
  2. Do you share your server?
  3. Does your website run some kind of a web application or just plain old html?
  4. Have you tried contacting you hosting service?
  5. Are all recent patches installed. OS/Application.
  6. Have you looked at the access log of the web server installed on the machine?

While this isn't an answer please supply as much data as you can. I will try and help.
