Ok, I ran Apple software update today and installed a security update and the latest iLife updates. Now whenever I open Acrobat Reader 8.1.2 it automatically starts opening (apparently) every pdf on my computer. The only thing I can do is force quit from the dock. Yikes. I tried downloading Acrobat again and reinstalling, but the issue continues. I can't seem to find any mention of the issue here on on the Apple support pages. Any advice?
