How to Install McAfee VirusScan: OS X


McAfee VirusScan uses on-access scanning to guard against all types of viruses and malicious code, including new and unknown threats. VirusScan offers unintrusion protection to block viruses, worms, Trojans, and other malicious code that attempt to infect your systems.
