It says to accept or cancel
also the information

Microsoft Windows
"C:\windows\system32\RunLegacyCPLElevated.exe"
Shell32.dll.Control_runDLL
"C:\Users\Robert\AppData\Local\AwDaGOCwqPn\CviejN.cpl"

is displayed in the popup.

This just started the other day. And have read several posts that it is some type of virus.

My antivirus software "AVG internet security bossiness edition 2011" doesn't see it as a threat.

Running "Windows Vista Home Premium" operating system

Any help or advice will be greatly appreciated. Thank you in advance.
