Overall...I am trying to code an antikeylogger. I am going to try and code it with respect with hook blocking procedure and signature based. As far as I understand...the hook blocking works by picking up the keyboard stroke and you can choose to let it through or block it. The signature based works by the program searching for known ddl files and registry files that are installed by the keylogger program. I have to write this program in vb.net. I plan to code it both ways. I need to find out how to identify a program's signature using vb.net code...which class. I also need to know how to block the hook using vb.net code.
