Annoying notice

I have been a notification for more than six months, and I don't know what the reason happened. How many times I know the source. I searched for the site that comes to me, but I didn't get anything out to me, and I searched Google about it, and why. What is the reason came out, but I noticed when I downloaded the calendar application, the topic started, a couple of weeks ago, I deleted it, but it's still to come to me, and it became a bit annoying.
