There is work to give the user more control over this that unfortunately didn't make it into Firefox 4 [1], but ultimately it's a battle that can't be won; on the desktop, apps can modify other apps. I suspect that this will happen to Chrome too.

Heck, since Chrome has to put itself into the users AppData folder in order to do silent updates, is there anything preventing malware from just screwing with the Chrome libraries themselves?
