MacAdware downloaded with AdobeFlash

I was looking at something on the web when i was asked if I wanted to use Flash and that  there was a new version. If yes then a download started and everything looked normal for an Adobe Flash install. When the install completed I had MacAdware Cleaner on my desktop. I've had this before and spend hours cleaning up numerous locations on my Mac. Not Fun. How can Adobe allow this to happen in their name
