Try System -> Settings -> Addons -> Enabled Addons -> Services -> Version Check -> Disable.
If when you select Addons you find yourself with a list of addon categories or addons instead of "Disabled Addons", "Enabled Addons", "Get Addons", "Install from zip" (et al) then select the double-dots at the top of the list to go back up the tree (like directories) until you get to that list at the top level. Then go back into "Enabled Addons" and carry on as above.
