Depict it as your home
If you forget to close your garage door or a window, a
burglar has an easy way of getting into your home.

the ones you don’t trust.
Remove the malicious scripts
It’s possible that hackers still have access or steal data
through installed exploit scripts. These will have to be
removed as well.
