Ever lose Adobe?

My computer is set for auto updates and I found a MS Windows NOTE BOX upon opening one day and in attempting to discover why, I lost all Adobe and Acrobat programs, yet still have the MS Windows box stating "Adobe Flash Player Update Service 11.6r602 stopped working and was closed" and a Windows note at the bottom stating, "A problem caused the application to stop working correctly.  Windows will notify you if a solution is available" and I now, at least six months later, am still searching for answers of where did it go, why did it stop and how can I keep it from happening again; as I have recently downloaded a trial version of the latest programs, but would like, if nothking else, to rid my screen of the MS NOTE BOX and I don't know how, does anyone?
