After having upgraded to the latest Microsoft Office for Mac version (v14.2.5), I started getting error/messages regularly when I log in to my computer (iMac 3.5gh intel i7; Yosemite v10.10.1)

One message that pops up is an Office Calendar Reminder message that states "Re: Overdue (Last Thursday)." [I don't have any calendar items relating to that message.]

Second message is actually an item in the Trash within Recovered Files folder named "MerpAD Database Daemon." Each of these items pop up/appear every time I log in to my account.

I've run Disc Utility and I've cleaned up as much as I know how, but no luck. I've looked on the internet for solutions, again, no luck. I've posted on Apple forums, but no response. 

I haven't seen any apprecable difference in computer operation since these occurrences, but want to eliminate this annoyance and any potential problems that may arise from them.

Any help here would be appreciated. I've attached screen grabs of each of the messages. Thanks for any help.
