Found this helpful, so I thought I’d post this. If you download a program (a .exe file) using IE it marks it as suspect. This isn’t that bad the first time you get prompted to execute the program. But when it’s a tool you use regularly, it gets annoying. But you can’t "unblock" it from an unelevated explorer window. And it prompts you before it elevates the binary if you try to run the binary as admin. So Matt points to a little tool that will let you access the file’s properties dialogs from an elevated context so you can unblock it.
