Acrobat Pro 9.4.6 Update Win7 pro causes IE to startup on startup

I work in a enterprise enviroment.  After Installing Acrobat update 9.46 on two Win 7 pro PC's. IE is automatically starting at startup.  I've checked the startup folder and msconfig for IE, Iexplorer.exe.  Neither is showing in either location.

This started happening right after installing the 9.46 update.  Anyone experiencing this issue?  Does anyone know of a fix SHort of a reg hack?  Thanks in advance.
