How to fix 'Moo virus' causing zoomed-in screen, inverted colors, and mooing sound on iPhone?

Hello, I am contacting in regards of a new Virus on iPhone. This virus is known as ‘Moo virus’ ‘Moo Moo Virus’ ‘Cow virus’ and more. I am the tech support for my family and friends, and my friends phone has caught this virus. It is from a shortcut called HH School Fights, but this, to my knowledge is just a regular shortcut.

At this time, the phone shows these “symptoms”

Excessively zoomed in screen

Inverted colours

An irritating Mooing sound made by a cow.

So, I would like to know if anyone has a “cure” because this virus is on a rampage, and a lot of people are getting it.

Hi, this is usually not a virus — it’s most likely a Shortcut or Accessibility setting causing it. Try this: delete the HH School Fights shortcut, then go to Settings > Accessibility and turn off Zoom and Invert Colors / Smart Invert.

Quick fix

Delete the shortcut.
Restart the iPhone.
Check Settings > Accessibility > Zoom and turn it off.
Check Settings > Accessibility > Display & Text Size and turn off Smart Invert or Classic Invert.

Else contact Apple Support iPhone - Official Apple Support

I believe that is often referred to as "karma."

Committing what can be considered a prosecutable computer crime as a “prank”?
