Why do i keep receiving multi media download messages?

[AC Question]

Is this a virus? I keep receiving multi media download notices from random people in my contacts. However my contacts are not sending them and there is no pic or any other visible media. Any help or explanation on what these are and how to stop them will greatly appreciated, thank you!
