Adobe Flash

Hi everybody :

                      A couple of days ago....I received a pop-up from Norton in reference to Adobe Shockwave Flash. Stating, due to the fact that this software was a gateway for intruders (for viruses).  I DISABLED it from my IE 11 MANAGE ADD-0NS(Toolbars and Extensions).   Now that I did this, I notice that any online videos won't play.   Is there a substitute for Adobe Shockwave Flash ?
