the goose is not a virus, all the videos that showcase is show the full functionality, it doesn't do anything else other than what you see.
no files are deleted from your computer, no damage is done to your computer, nothing is changed. it is just a goose
take most of the videos that you see claiming that it is a virus with a pinch of salt. they use the word virus as it gets more clicks than saying something like "I got a goose for my computer"
perhaps also look at the description of the video, do you really think large youtubers are going to post a link to a virus in the description of their video.
