SecureMac is shipping MacScan 2.4, the latest version of its anti-spyware package for Macs.

MacScan detects, isolates and removes spyware from Macintosh computers using both real-time spyware definition updating and unique detection methods. The software also manages internet-related clutter on your computer.

This version also addresses issues identified in previous releases, with updates to the removal of Firefox tracking cookies, as well as enhancements to the way MacScan removes tracking cookies from all browsers.

The company is also now offering Mac users a free 30-day trial of the anti-spyware software. Internet file cleaning sessions are now saved and can be re-used on future scans.

The upgrade is free for registered users of the $24.95 application.
