I received an Adobe update notification yesterday for Adobe Reader, just clicked OK, it asked for my system password and did it's thing.
1/10/13 11:25:15 AM [0x0-0xcc5cc5].com.adobe.ARM[30195] installer: Warning - If you have Adobe Reader running, you will need to quit it in order to continue.
Other then that, not a clue what's happening with your system.
