rapier57: "You may just want to call the FBI and let them take a look."
LOL! Have you ever called the FBI for an IT attack? My job requires it; and it really is just procedural. Doesn't matter if you have a 10 dollar network or a 10 billion dollar network you are better off just unplugging the network cable than waiting on the FBI.

The feds can not afford top level IT security staff; next time you have them analyzing your compromised server rapier57 ask them to explain the OSI model to you and listen to the sound of your own heart beating 'cause that is all you will hear. LOL.

The best advice for the OP, and it has already been given, is to get some pros to take a look. Pros cost money, not everyone has money and that's why so much ownage is still going on.
