[Virus Error] inserted in front of the email subject
For the second time today, I have received a series of emails from someone which has the following text: [Virus Error] inserted in front of the original email subject. The emails were received on both my iPhone 7 and iPad Air 2.
Both times the emails were forwarded from my university account to my iCloud account because they are on a list of critical contacts in Outlook. There was no indication of a virus infection after the emails arrived in my university account. One of the contacts was internal and the other external to the university. I have received other emails to my iCloud account from both internal (forwarded) and external accounts that did not have this text inserted.
Does anyone know if this indicates a legitimate concern?
Thanks.
iPhone 7, iOS 13
