How to stay safe
If you ever receive a message or a link from someone or people you don't know then just delete it so if it has a virus connected to it you wont get it.
If someone sends you a friend request but you do not know them ,decline them.
If there's a link that says something like the picture then never click them because they lie to hack your device.
Download an anti-virus software which will prevent all of that and will keep your devise clean and un-harmed.
If or When you do update it every day so you know that it's safe.
It's unsafe when you talk to people who you don't know or even if you haven't seen each other.
Don't open links that you don't know about especially if you don't have an anti-virus software.
