RUN AND TASK MANAGER DISABLED
it has been disabled by my administrator, this is as a result of a trojan horse

A Trojan horse program is not a virus. The key distinction between a virus and a Trojan horse program is that a Trojan horse program does not  replicate itself; it only destroys information on the hard disk.
 A Trojan horse program disguises itself as a legitimate program such as a game or utility. A Trojan horse program often looks and initially acts like a legitimate program, but once it is executed, it can destroy or scramble data. A Trojan horse program can contain viruses, but is not a virus itself.

the first thing to do is to download a trojan removal, install and scan for trojan and after that follow these steps below:
