Renaming .exe extensions to random numbers avoids viral infection ??!!!??

[vidur]

a software written in python to change the extension of all existing exe files on a system to a randomly generated integer would prevent a conventional virus as knowing the file is an executable and hence from infecting it. i know there are easy ways of getting around this. so this method cant be widespread. but would it work on 1 machine ?

one could write a program to run these exe files with integer extensions quite simply

Or determine it's executable from it's content, .exe files have a special header on Windows systems don't they? I'm unsure, sorry. It depends on the virus, I would say.
