Adobe flash and or air problems

i started have problems with adobe flash and adobe air last year after a update and it has only gotten worse to the point i am now uninstalling and reinstalling twice a week its only on certain sites where theres problems. i can understand and dont mind doing this once a month but now twice a week is going to far. i have completely gone thru computer and  keep it cleaned. also it works good for a few days after reinstall with no adjustments or changes else where then stops working on some sites and i start getting crash messages and freezes near constant. every day i go thru clear cache and cookies thru out. i have had computer looked at and its not the issue, its something to do with adobe. any ideas would be helpful. getting tired of this problem.
