What is "macscan"

MacScan is an anti- malware utility for Apple's Mac OS X developed by SecureMac. It is aimed at removing malware (including spyware, Trojan horses, keystroke loggers, and tracking cookies). It was the first anti- spyware program released for Mac OS X. In addition, the application scans for remote administration programs, like Apple Remote Desktop, allowing users to verify that such programs are installed only with their authorization.

Unlike other anti-malware applications available for Mac OS X (and other systems), MacScan scans exclusively for malware that affects Macs, as opposed to scanning for all forms of known threats, which would include Windows malware. Given that there is considerably less Mac-based malware than Windows-based malware, MacScan's definition files are smaller and more optimized.
