Packer

[Squidge]

You can try ASProtect or Telock, or a combination of very other protectors. Most however have a dedicated unprotector program by now, so the best protection would be your own PE protector. But look how others are cracked first before designing it.

However, if your going to release your EXE onto the net, it doesn't matter what protector you use - within a day it'll be unpacked/deprotected and then RE'd to death.
