yes compressed or *encrypted*
If the OS has a database of all the public key of software houses,
if M.exe is a encrypted program of Company XX
the loader of the OS could take the public key of Company XX
encrypt it [on the fly] and jump on it.

If a crakker want to crack M.exe he has to know the secret key of
Company XX or change the code in the memory space of that running
program.(in many OSes seems to me that the memory space of a program
is closed to other process)

Regarding Internet **why** OSes seems to have the default in allowing
*every* FTP-telnet-http-all *fu?king* protocol- IN EXIT for the
home-PC ( and change it in a world server of resources) ???
