'Tea Timer' is part of Spybot:Search and Destroy, so I am assuming you have it so you can either uninstall it or try the following.
Right click Spybot in the System Tray (looks like a calendar with a padlock symbol)
Choose Exit Spybot S&D Resident.
Open Spybot S&D.
Click Mode, check Advanced Mode.
Go To Left Panel, Click Tools, then also in left panel, click Resident.
If your firewall raises a question, say OK.
Uncheck the box labeled Resident Tea-Timer and OK any prompts.
Use File, Exit to terminate Spybot.
Reboot your machine for the changes to take effect.
