rundll32.exe is annoying me already

Is is safe to set rundll32.exe to "Always Permit"??

I get this message alot. Like when I open some things in the control panel or when I plug in a usb device...

 

It is probably safe to just allow it, but I just allow it on request.

 

Is there any benefit to keep allowing it on request?

Is there any type of virus/worm or something that will use rundll32.exe in a malicious way?

 

Rundll32.exe is used to run DLL's as programs, and is needed to open some applications in XP, programs, etc (Ex. Opening Ms's Security Center in XP SP2 uses rundll32.exe to open). Detailed info of what is rundll32.exe:

Rundll32.exe is susposed to be located at C:\WINDOWS\System32\rundll32.exe. Seeing rundll32.exe somewhere else is most likely a virus or trojan since many malware application try to pose as valid applications/files. I allow this file on request also, just to know when a program or app. is trying to open/activate.

If any of my information above is invalid...I'm sure somebody will correct me
