I think the user is enquiring about anti-theft features on Android. Do not enable this when you are not the account owner.No, he/they CAN'T. He can do full and quick device scan and disable components and that's all. They can't hack, infect or lock your device, steal passwords or anything malicious. Of course, the seller can remove the buyer's device from MyKaspersky at any time, but they won't do it.
When something is breaching the rules and regulations of the business/provider, it is not genuine.The licenses are genuine, the seller just ''shares'' them with the buyers.
