iPhone Calendar Virus Alert

I'm seeing an event on my iPhone calendar with a description of "Apple iOS 17 ™️: Virus Alert ⬇️" followed by another event with the following description "Anna, 25 ans". Both scroll to the current day's calendar at a different time.

I have not clicked on either one of these events in fear of installing a virus, but would like to find a way to remove them. I have already gone into the calendar subscription folder, but they do not appear there. Any suggestions on how to resolve this would be greatly appreciated.
