Additional info on 0access rootkit infections.....
If your computer is infected with Rootkit.ZeroAccess, a BackDoor Trojan.
One or more of the identified infections is known to use a backdoor.
This allows hackers to remotely control your computer, steal critical system information and download and execute files.
I would advise you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.
Though the infection has been identified, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS.
