Do Apple Computers require an Antivirus software program?

As a lifelong Windows user, I just bought an Apple Macbook Pro. I was wondering whether Apple computers require Antiviral programs as Windows products do.

I typically use Norton programs and have Norton Internet Security 2006 installed on my primary PC. If such a program is necessary, what program would you recommend?

What Apple compatible antivirus program is the most popular?

Apple Computer issued on Tuesday updates for its Mac OS X operating system to fix 26 security flaws, some serious.

Several of the vulnerabilities affect the way in which Mac OS X handles images and the file-sharing capabilities of the software, according to an Apple security advisory. Other flaws were found and fixed within components such as Fetchmail, file compression features, and DHCP networking functionality, Apple said.

The vulnerabilities could enable a variety of attacks, security company Symantec said in an advisory sent out to customers of its DeepSight intelligence service. "Remote attackers can execute arbitrary code, trigger denial-of-service conditions, elevate privileges, and disclose potentially sensitive information," Symantec said.
