Remove an Add-on

[citapinc]

Ever since I uninstalled a Google Calendar add-on, my error log shows the following:

Mon Jan 9 04:52:08 2012 [2803][afd3098a-0943-9644-cb63-4eb3622f307e][ERROR] Unable to load custom logic file: custom/include/Calls/google_calendar_users.php
Mon Jan 9 04:52:40 2012 [3876][afd3098a-0943-9644-cb63-4eb3622f307e][ERROR] Unable to load custom logic file: custom/include/Calls/google_calendar_users.php

It seems like the uninstall process didn't remove all of it's hooks so Sugar keeps trying to call this PHP file. Where is the hook table or hook call located that's trying to call this .php file so I can fix it?

It would either be in custom/modules/Calls, custom/modules/Meetings or custom/modules/Tasks
