Receiving hundreds of alert email from my me.com account; don't know why. Checked the calendar and reminders but found nothing.

Since yesterday I am receiving an alert email every few minutes sent from my me.com account to my gmail account.

The content of the message is just 29 Jun 2014 09:00 :

In my calendar there is nothing signed for that date, nor in reminders.

How could I solve the problem. Where to look at?

Looks like a virus.

Thank You
