I've used Macs for over 20 years and I have never, ever had a virus. The anti-virus software itself, ironically, has caused more problems for me. I uninstalled McAfee VirusScan within a month after I could no longer stand the drain on system performance. On Mac OS X, there are a couple things I do to improve security: - I run as a normal user, so that I always see (rare) prompts if admin privilege is being requested. - I am extremely skeptical of software installers that "require" privilege. I usually decide to bail on them.
