Brief Description 

    

Agent.BCU is a backdoor that attempts to download a file from certain website to the affected computer.

Agent.BCU does not spread automatically using its own means. It needs an attacking user's intervention in order to reach the affected computer. The means of transmission used include, among others, floppy disks, CD-ROMs, email messages with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc.

Visible Symptoms 

    

Agent.BCU is difficult to recognize, as it does not display any messages or warnings that indicate it has reached the computer.

However, on Windows XP computers it has the following symptoms:

  • If the file belonging to Agent.BCU is run and then any other file is run or if the affected computer is restarted, an Internet Explorer error message is displayed on screen.
  • The message indicates that an error has been produced and the Internet Explorer process is going to be ended.
