I have an iCal calendar synced with a Gmail account and whenever I add an event, it adds an email alarm and a message alarm.
It's really frustrating since this is synced across 3 computers (OS X 10.5, 10.6, 10.7) and two mobiles (one Android, one iPhone 4S) - alarms going off everywhere!

When adding a new event, the alarm is set to "None" by default. It seems as though it adds the alarms immediately after it has been added.

Just to be clear, the "Add a default alarm to all new events and invitations" is turned off across all the computers and as far as I can tell, there is no option to do enable/disable this on my Android device or Google Calendar.

Has anyone run into this before or know what's causing it?
