Why are Windows and all other software programs' dll's not digitally signed?
Wouldn't this make it a lot easier to determine what files on a computer were
valid, and which were potential viruses?
When a dll or exe or cab file is signed, and you right click that file, you
will see a tab for "Digital Signatures" and you can verify that the file is
actually from who it says it is from. The "Versions" tab on file properties
shows the company but this can be easily spoofed by anyone who writes their
own program.
Whenever we have a virus, we painstakingly go through each service and do
google, and symantec searches on it, to try and verify its authenticity. A
digital signature for each file would allow this process to be automated. The
computer could be scanned and all unsigned suspect programs could be
identified automatically.
