Antivirus is nothing but a security software that protects your computer from unknown threats like malware, viruses, spyware, and ransomware. Apple introduced an in-built security software named as XProtect for the Mac computers from the Mac OS 10.6 version. It warns you when you try to open a suspicious file on your Mac computer. For the Mac OS x 10.7.5 version, Apple introduced Mac GateKeeper that acts as an additional security layer for the operating system. It alerts you from downloading malicious software. You can also install antivirus for Mac Os x 10.7.5s from third-party such as Bitdefender Total Security, Kaspersky Total Security, and McAfee Total Security.
