July 22 - 12:05am EDT   Anyone who has used a Windows PC knows that you absolutely must have an anti-virus program or else your computer will likely crash the moment you connect to the Internet.

Apple's switch to Intel processors, and the various virtualization processes that exist for running Windows, have eroded that confidence for some users. Although Apple is usually on the ball with fixing system vulnerabilities, some larger problems can go for several days or weeks before a proper fix is available. Symantec's Norton AntiVirus 11 aims to compliment the Mac OS' natural sturdiness by providing anti-viral services and fixes for security holes while Apple works on a true solution for the problem.

Crucial to the latest edition is official support for Mac OS X Leopard, guaranteeing maximum compatibility; also included, however, is improved performance in file caching, using on-access and on-demand techniques.
