MacBook Pro has been taken over by Adobe installer

[Dennis74]

When I try to shut down my computer, I get a message that says I can't do it because a program is running. It's caused by an Adobe Installer. It has spread to an older MacBook on the same network. Ideas? I have tried using Force Quit, but it shows up again when I try to do anything else.

Hello,

I haven't heard of this issue before, especially if it affecting multiple Macs. Could you upload a photo of the message on the screen?
