An image processing apparatus according to an embodiment includes: a detector which detects an occurrence of an event; a display which displays notification information regarding the occurred event; and a controller which restricts operation authority over the notification information displayed on the display to a specific user when the notification information corresponds to a notification for the specific user, and makes the operation authority over the notification information di splayed on the display unrestricted when the notification information does not correspond to a notification for the specific user.

An image forming apparatus for executing virus detection processing on received data includes a hardware processor. The hardware processor is capable of executing either first acquisition process for downloading and acquiring a pattern file used in the virus detection processing from an external network or second acquisition process for downloading and acquiring the pattern file used in the virus detection processing from an internal network or a connected storage device. The hardware processor switches between the first acquisition process and the second acquisition process in accordance with a usage environment of the external network.
