Surely if it's not informed consent then it's not authorised access to your computer. Unauthorised computer access is illegal in USA (CFAA) and UK (CMA), at least. If it in anyway restricts bandwidth or causes other harms, eg uses up the last of your HDD space causing an issue, then that's an additional crime according to UK law. These laws shouldn't just be applied to individuals.
