What you need to do is, when you uninstall shockwave from add/remove programs, go to regedit and look for adobe, and see if you can find a shockwave registry and delete that. Make sure you backup your registry first.
also update your firefox and chrome browsers.
don't use ccleaner for registry cleaning. Use little registry
http://sourceforge.net/projects/littlecleaner/ccleaner is great for cleaning temps, recycle bin, etc.
after you uninstall shockwave, run little regis, then run ccleaner, then update your browsers, then reinstall shockwave, and flash. Let me know.
