Hello,
Well my advice for Sara when using the web would be 3 things.
1: Never tell anyone where you live,Your name, Or any other personal information.
This is important as it will keep you safe and others that are in your family.
2: Get anti virus hardware on your devise.
This will help to stop bad people, and bugs/glitches,this will also protect you from information thieves.
3: Make sure to keep your passwords saved on paper.
I know a lot of people use, google(ect.) to save there passwords to make everything easy, but a good way to never loss them is to wright them down.
Have a great day!
