Simple but Elegant
Like other PC Tools offerings, iAntiVirus steers clear of bloat - providing exactly the features you'd expect in an antivirus software as unobtrusively as possible. For example, there's an option to disable the dock icon if you want to keep things tidy. But if you do leave the iAntivirus dock icon enabled, you can drag and drop files and folders there for quick and easy scans.
PC Tools iAntivirus features realtime protection, scheduled quick scans, and scheduled updates. Monitoring mode keeps iAntivirus working truly in the background, ideal for those who don't want to be disturbed by alerts or anyone trying to conserve laptop batteries.
PC Tools iAntivirus detects and removes Mac-specific malware only. This can be either very good or very bad, depending on your perspective. While a Mac-only focus keeps iAntivirus running lighter and faster than other Macintosh antivirus software, it also means a Mac user could inadvertently share files infected with Windows-based malware. Macro viruses, for example, aren't detected by iAntivirus - corporate users sharing Office documents between Windows and Mac users will want to make sure macro virus protection on both sides is enabled.
PC Tools iAntivirus is supports Intel-based Mac OS X v10.5 and higher, and is free for home (and home office) use. Corporate users can purchase a license for approximately $30 which includes free 24/7 tech support.
