My Internet Explorer 11 keeps crashing on start-up and...

Just so you know, I have a Dell Inspiron Laptop 1545 with a 64 bit Operating System and i have Windows 7 and Internet Explorer 11.

My firefox is working perfectly fine. But my Internet Explorer 11? All of a sudden (i was on a regular internet page aka Youtube) it just crashes. And now anytime I even try to start Internet Explorer, it continually has multiple upon multiple error/crash messages of "internet explorer has stopped working" and won't quit showing up unless i close the page. I have Norton Antivirus and did a clean sweep with it, I went to my internet options and deleted cookies/temp internet files, and i even went to try clicking on the 'Internet Explorer (with No Add-Ons) but when I do that? It does the same thing. And this just came out of nowhere (but again, my Firefox is working perfectly fine). What is the deal? And I haven't downloaded/had any recent updates. Any help would be much appreciated.

Its apparently a problem with a Noton update. They posted a workround on their site that worked for me:

From the Norton forums:
Go to Control Panel, Internet Options
On the Advance tab, under group security enable these two Options
"Enable 64 bit processes for enhanced protected mode"
and
"Enable enhanced protected mode"
