- Extreme FW/AV Kill (Over 750 AV/FW in the list!)
- Encryption
- Small 32kb unpacked, with all options enabled (FW/AV kill, Melt, URLs etc)
- Ability to pack with either fsg or upx!
- Server has good Error Handling
- Easy to-use GUI
- If UPX packing is specified it also scrambles the Server =)
- If it cannot kill a process it operates silently without errors
- Runs in the background (Hidden from taskmgr etc etc)
- Ability to define wether downloads should be executed hiddenly, visible or don't execute at all   just download them...
- Undetected from ALL anti-virus software! Yup...
- No limitations on how many downloads that can be downloaded

* v0.7 changes: *
- Undetected.
- Stubs are Compiled in Visual Basic 5 (Thanks for suggestion Alchemist.)
- Using fsg 1.31 instead of 1.33 because it didn't like the new Stubs :(
- Both Stubs should be smaller. None AV-Stub is like 11kb Unpacked now.
- Clean-up in the "Client".
- Added ZoneAlarm Mutex Exploit By Alchemist to the AV/FW Stub.
- Much better FSG Scramble.
