When you bid on this project please send me a PM and answer these questions:
(I'll attach these questions in a text document if it will be easier to answer).

Do you have advanced rootkit/windows security knowledge? If so, can you explain your experience? (Please be as elaborate as possible).

Have you coded a program like this before? If so, do you have a demo? If you do not have a demo can you provide so I can make my decision to select you as the coder? 

Will you provide full source code after transaction is complete?

Will you be able to provide after-support? Say anti-virus detects your program after 2 weeks we close this project, will you modify the program to make undetectable again? If so, what would be the time frame of after support?

Do you agree that I will have full rights to this program and you cannot resell?

Which language will you code this program in?

Which method will you use to create a kernel level driver for logger? or if none of these methods please explain your method you plan on using.
