this is the situation.
I want to create an ecrypted trojan behind a picture ( Jpeg.)
- trojan is supposed to send data to a email adres.
the data that should be send is a complete list of files that are on the computer.
and ofcourse the trojan should not be visible in the process list.
that is my first step not to hard but some 1 please help me create this

second.
once I found the files I want, I need to send another trojan that helps me send the requested file I want.
yet again how to create this.
does some 1 have a good really good site that explains the easy way?
I have seen lots of tutorials wich bigass sucked cause they did not give me the lines I need to create the trojan.
thnx in advanced
