I'm a gamer and one day i was playing mine craft when this blabbering thing just showed up. I went to activity monitor and there was a process called com.apple.dock.extra. From the first day there was a annoying voice all the time and when i went to internet pages, i could not scroll down as it would go back up to the top again. Just yesterday i was playing mine craft when my up key stopped working. After some investigating, i think it has to do with com.apple.dock.extra. Whenever i press up, the annoying little black box goes up to multiple links and says them out to me. Finally, there is a big black box that appears telling me where my system is. My computer is a 13 inch MacBook Air version 10.7.4 and i have Mac OS X Lion 10.7.4. I have a 1.8 GHZ processor. Could someone PLEASE tell me how to fix it, as this is my school computer.

It is possible to achieve this effect using Calendar and Automator:
Open Automator and create a Calendar Alarm.
Use the tasks “New mail message” and “Send Outgoing Messages”, customize them as required, and save (⌘S).
An event will be created in Calendar automatically. Move the event to when you want the message to be sent.

The answer I put there should work if this hasn't fixed itself via time or an upgrade to a newer OS. Just send the com.apple.dock.extra messages to /dev/null by editing /etc/syslog.conf
