The fact that everyone is panicking about this could be the April Fools joke itself. The majority of people who get viruses are users who go to sketchy sites and download stuff from sketchy sources, or are just stupid users in general.
I have a backup of my data on an external hard drive. If I lose my data, I just restore from an image. If that image is infected, I can wait until they can remove the virus and do so to the drive from another computer. So I'm not exactly concerned.
