Inspiron 1520 won't update

Everytime I attempt to update it closes the update page, and gives me an error message that says "A malfunctioning or malicious add-on has caused Internet Explorer to close this webpage" I tried to turn off the data execution prevention security feature but it didn't work.  What can I do? PLEASE HELP!!!

Google for them.  They both have free editions.
