There are several variants of this virus. The original variant contained the following text:
Este programa fue hecho en Chile en 1992 por CPW.
It also had an activation routine: by random, it started to replace the characters typed from the keyboard so that the text was replaced with a sentence: "You are here CPW!". This effect stopped if user pressed Alt-anything.
Cpw is a retro-virus and will delete SCAN.EXE if it's attempted to run.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
