I am getting a message in the middle of my imac screen instructing me to hold down the on-off button and turn off the computer. The message is in several languages and completely takes over the computer disabling the mouse and all other functions. The only option is to unplug the computer or turn it off. I'm concerned that this is a virus. It does not look like it's related to Apple or the imac OS.

iMac, iOS 7.0.1
