From what I've read, Flash is going away on the mobile browsers, but not soon enough. Hopefully this will extend to the desktop versions as well since the new HTML 5.0 supports this technology built in. The problem with Flash is it went beyond just being a multimedia player and became an interface which is capable of doing things beyond what the original concept was. This then became a hodgepodge of add-ons, plug-ins, updates, patches, etc., which created security holes. A good analogy is building a simple 4-room house. On this little cottage foundation, someone decided to add on a Victorian turret, multiple floors, rooms, bay windows, and porches. If this isn't done properly, we now have a house that will collapse under its own weight due to the foundation being unable to support it.
As I said before in this thread, as users we have to watch where and what we click. We have to be sharp and savvy about our computer usage and not click on things because they are sent to us. When I worked in the corporate world in IT support, I gave computer safety training lessons to the end-users. This saved the companies money due to lost employee production, and additional IT support needed to remedy the ensuing mess that had occurred.
Keep in mind that if we go to the same websites every day, rarely venture off course, don't click on or accept embedded emailed links, and type rather than click on search results, we'll be pretty much immune from this security issue.
