I don't think my computer is safe! You know, sometimes my system is broken and some of my important data disappear and I always regret for that. So I have to backup to external hard drive so that I won't regret for that again. But do you think it is absolute safe by doing that? I don't think so. What if my external hard drive is stolen by someone?
So I think we should improve computer safety as soon as possible, I mean there are still many unsafe factors in our computers. You may don't notice it,but when you lose something, you will feel pain for them, so keeping an eye on your computer safety is always good for you.
