I am certain I was hacked as the person who hacked me took photos on my computer and posted them to my account on a website. I'm not sure how they hacked into my computer since my only contact with this person was through Skype. I never clicked any links they sent me nor did I send them any files. What do people suggest I do? I have backed up all files on my computer and deleted them off my computer. I did not realize my firewall was turned off, so I turned that on immediately and I also encrypted all files on my computer. Do I need to go ahead and restore my macbook air now? I would like to stay away from doing this but I am prepared to do this if needed. Thanks in advance for your help.
