I have been learing about using my laptop right you should only on your class site or the tab you are supposed to be on if you dont you will get in trouble with your teacher and you can get a virus on your laptop.If you dont listen this will happen you have to tell them what happen and you get in more trouble so you should only be on the thing you are meant to be on and you always should not touch links from random people if they send you one and if you do that may install a virus.Plus if you are using a hard drive be careful beacuse is may a virus in there and it will break your device then you will no longer have it so allways be careful and always be in th right place at the right time.
