It's a MSN stealer with only 8,50KB of code UNCOMPRESSED

(and the settings are even crypted xD)
It emails you the stored passwords of Windows Live Messenger.
[Usage]
You have to open Builder.exe and fill in your information and press patch.
Stub.exe should be in the same folder.
Be sure you use a valid GMAIL account, otherwise you will get a error message.
