Install a genuine antivirus application – and keep it up to date. To counter the moves of malicious viruses and hackers use Bitdefender Antivirus for Mac.

Deactivate all sharing preferences in the sharing pane – including iTunes and iPhotos. At some point if there’s a need to share – limit the access of other systems to your personal Mac.
