The CPW is a rare virus from Chile that will install itself memory at the top of the system memory. Once it is memory resident it will effect the .COM and .EXE extentions when they are executed. When executed, a code string will be shown
"Este programa fue hecho en Chile en 1992 por CPW." "C:\COMMAND.COM" "Feliz cumpleaños CPW" "You are here CPW!" "ULS"
Upon activation, the user will be greeted by a bunch of "You are here CPWs!" on the startup prompt of DOS. It will also delete Scan.EXE.
