Adobe Reader Updater legitimate?
It seems like it is legitimate for the following reasons:


When I launch Adobe Reader, it automatically updates the UI of the application to tell me that Adobe Reader needs to be closed in order for me to install this update.
My current version really is one below the one it's asking me to update to (10.1.2).
Under Adobe Reader's Update preferences, I had it checked to automatically download and prompt me to install updates.
Adobe's website shows that 10.1.3 really is the latest version.
When I run Help > Check for Updates, the same Adobe Reader Updater application is launched (or rather focused).
