hm... what about Process32First (used by some protectors, but also disallows other pograms to start it), ZwQueryInformationProcess (Used by new VBox HASP SL), and the method used by SDProtector (didn't analyse what it uses)?
all i do is writing tutorials, but not taking part in such contests which helps developing protectors. same as Code-Lock with their "special rulez" you have to explain them more or less how you cracked it (this thread about code-lock was created by you dyn!o
)
