McAfee Internet Security

McAfee Security for Mac is an integrated suite of products that uses advanced heuristics and protects your Apple computer from viruses, trojans, spyware, and other malware. It scans files, folders, applications, local or network mounted volumes to find a threat, vulnerability, or other potentially unwanted code and creates a detection report. Scanning can take place immediately, at a specified time, at regularly-scheduled intervals, or each time an item is accessed.
