prorat is awsum, but won't work with w7 :S (for meh)
just binding a regualr keylogger to antoher file WILL work, but antivirus always wil ldetect it, you need a payed/pro version of some sort of keylogger (like prorat or other rats..) to make it undetectable. or just tell your victim how the prog (fake prog) works, and explain why he have to turn off his antivirus... :S
