Comments 
Cero 1 is a Visual Basic trojan. Cero has an edit server that allows the server to send notification to an ICQ UIN when your computer comes online. This trojan appears to be buggy. When we tested it, the server crashed. We are not sure that any of the listed features actually work. 

How To Remove 
Quick fix: no quick fix programs
Manual removal:

  1. Rember the file  in the cerokey in the registry located at HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run Which can be done with regedit or any other registry editing program.
  2. Reboot the computer or close the file in the registry. 
  3. Delete the trojan file that was in the registry.
