I've been running on OS X 10.9 for a few weeks now, and haven't had any problems, but just today whenever I go to finder and click on the applications tab, Microsoft Office installer, Silverlight installer, and Adobe Flash Player installer all open automatically. I was wondering if this has anything to to with OS X 10.9 or if something is wrong with my system. Also if this is happening to anyone else and how I can stop it?
