Apple’s malware detection and file quarantine

This is a system built by Apple, that puts downloaded files in a sort of quarantine. It uses Code certification to make sure that the app you have downloaded is coming out of the safe source. The system also keeps your regular security updated. The system works in the way of reminding you about the downloaded file and asks if you are sure that you want to open it. Apps without Code certificates will not be opened due to your security system. Those apps that are listed as malware, will not be opened at all. The system will only ask if you want to delete them.

Creating the database of malware made it possible for you to set your security updates on automatic. In this way, you will be sure that you are protected. But no software can be 100% protected, so make sure not to download suspicious apps, especially the newest and unfamiliar ones.
