Hello my friends at Cheggs since I'm not able to use your help with my labs, I can at least reach out to you for your expert help on some questions

What are the best methods to protect data in transit?

What methods also guarantee that data on a desktop or laptop cannot be used by a thief that steals it?

On a side note, I just purchased the new Windows Surface Pro, and I'm wodering what's the best free or purchaased virus protection and malware protection I can get for my machine. Thank you for your help.
