I am receiving a hack notification on the calendar
Dears,
I am receiving a virus notification on the calendar could you please check is it fake or not before formatting the device ?
iPhone 12 Pro Max, iOS 14
Question marked as
It is not a hack.
There is no need to do something as drastic as formatting the device.
If running iOS 13 or earlier versions, check: Settings - Passwords & Accounts - Accounts - Any rogue entries here? If so, delete the rogue account.
If running iOS 14, check: Settings - Calendar - Accounts - Any rogue entries here? If so, delete the rogue account.
