adobearm_ucb.exe in c:\users\username\appdata\local

Has Adobe recently implemented a new process to ensure that Acrobat Reader stays up to date? I have noticed that I am now receiving AppLocker alerts because adobearm_ucb.exe is trying to run in the user profile folder. The Adobe Update Service, adobearm.exe, is still functioning from the Program Files folder. The adobearm_ucb.exe process is digitally signed by Adobe and seems to be legitimate. I am just wondering if this is meant to replace adobearm.exe or if it is a supplement to it.
