Ie 9 passwords and possible virus

How do I save usernames and passwords in ie 9. I followed instructions and it still does not work. I also noticed when I boot up, before the user icons show and on dark screen I get a box pop up with this message setting up User settings "RunDLL32IEDKcs32DLL.BrandIE"
I don't know if this is a virus or not. up User "RunDLL32IEDKcs32DLL.BrandIE"
I don't know if this is a virus or not.
