Website security certificate/ Adobe flashplayer install crash

[kmespanet]

My computer is on the fritz. I am having problems entering websites due to expired website security certificates. A window will also pop up saying that Adobe flahplayer Update Service 11.6 R602 has stopped working. I tried to download the latest version hoping to fix whatever problem it is and is and the download crashes saying Actionlist not found. Sound familiar?
