Error messages "Access violation"

Last time I shut down my Windows 7 32bit computer I had 7 "Access violation" messages appear at the start of the shutdown sequence. They were as follows :-

Access violation at address 004709DD. Read of address 00000010.
ditto 699181F3 ditto 699181F3
ditto 004709DD ditto 00000010
ditto 694C5405 ditto 694C5405
ditto 00406A2C ditto 00000010
ditto 00000000 ditto 00000000
ditto 004709DD ditto 00000010 (again)

I do not know what any of these mean or refer to other than the box they were in had a heading 'TeaTimer'exe

Can anyone assist. I just closed each messsage down so Windows could shut. Do I have to do anything or what?? Thanks uptonhowitt.
