Norton Utilities 14.5 and clean disk when using IE 9

I thought I might ask before experimenting if anyone new of any "bad" cleaning areas when using the new Internet Explorer 9, I want to be sure the "cleaning" will not disable or harm the browser in any way.

 

I am running windows 7 pro 64bit and the final release of IE 9

 

I have used the Utilities clean disk reliably with IE 8 and I wonder if all will be expected to go well when using IE 9

 

Thanks in advance -- Bill
