Code signing and firewalls/anti virus programs


I want to sign my code, such that when my customers are downloading my .exe and .ocx files they are shore the files are secure.
But my question is, if my customers have a firewall and an antivirus program of any kind (ex. Symatec og Comodo firewall), will the firewall and antivirus program interrupt the file download.
If my customer tries to download .exe files now when the files are not signed, often the firewall and the antivirus program will interrupt the file download.

Will all kinds of firewalls and antivirus programs recognize all kinds of signed cod (signed .exe files and .ocx files) and “let them trough”?




Up to my knowledge, i dont think firewall and av programs will not check for the certificate of de files.It wi be testing the signature with its database…
