Yep I also did as well during my first night! After getting my first jumpscare from mommy Lisa, I also left the tab open to fetch my laptop's charger, only to return to Raiden just coming closer as well, before exiting the application, only to see that she's occupied my desktop wallpaper too XD. I thought it was pretty cool though, so I don't think it's a virus. I think it's one of the easter eggs that the description mentioned.
