All my events get an alert set, event though I did not set one myself!?

  1. Go to http://www.google.com/calendar
  2. Log in with your username and password
  3. When logged in, click on Settings
  4. Next, click on Settings for Calendar
  5. A new screen will open, click on Calendars
  6. For each calendar, click on Alerts
  7. Remove the default alert by clicking on Remove
  8. Click on the Save button
