Notification of a Virus

Go to Settings ➔ Calendar ➔ Accounts and under Accounts see if an unknown calendar account is listed. If it is then tap on it and then Delete account.

Note that it is not a virus. It is something that got added to your calendar because you may have accepted an offer from a pop-up on a website unknowingly. Please be careful out there.

That's just a bunch of junk. So, delete it, and remove of it from your Archive folder. You'd be set from there.
