DarkCrypter encrypts your files and generates payloads to evade all anti-virus vendors. Released to a particular forum for $350, reversed in 3 weeks and free for you.
EDIT Will be uploading the complete source code once complete.
EDITEDIT Updated and final version decompiled, reversed, authentication removed and source code collected and zipped. Use this for educational purposes. I'm not responsible for what you do with this.
Peace + love ^B
