Its called a crypter, also you shouldn't mess with things you don't know of. The fact that your asking this means you know little. Crypters combine two programs, and some even have the added feature of making them less likely to be detected by antiviruses. Next time google it.

shut up coon its not a crypter, a crypter is somthing that encrypts -.- i suggest you dont talk if you havent a clue what ur on about.
