Symantec has introduced Norton AntiVirus 11 for Mac, featuring support for Mac OS X 10.5 Leopard.

The software furnishes vulnerability protection technology, which watches the web application layer. Norton AntiVirus automatically detects and removes viruses, scans and cleans downloaded files and email attachments, and protects against software vulnerabilities.

To address the growth of multi-platform PC and Mac environments, Norton AntiVirus 11 for Mac scans for both PC and Mac vulnerabilities, viruses and macro viruses.

Symantec promises performance and engine improvements to ensure better compatibility and less impact on system startup and resource usage. Product, virus definition, and vulnerability protection updates are automatic.

A new Norton AntiVirus dashboard widget gives a quick summary of system protection and status. This also offers a 'snooze button' scan, if a Mac user's engaged in another task on their computer they can reschedule the virus scan for a more convenient time.

For power users, Norton AntiVirus 11 for Mac can be accessed using the Terminal, bypassing the application completely and allowing such users to add antivirus scans and other capabilities to their own custom scripts.

Norton AntiVirus 11 costs £39.99.
