Norton's Internet Security 2012

I currently have this package and my renewal is due in December. When I click on "Renew", I see that the package price is $39.99. That's fine. But, it also includes another piece of software entitled, "Removal Assurance", which cost an additional $8.99. I have tried various ways of de-selecting that option, but it stays on the final bill.

 

I can purchase a boxed version of Internet Security for less than the two renewal packages Norton's proposes. Is there a way I can get just the Internet Security software, without this new Removal Assurance program? Or, is it necessary to have both?
