Only if you run Windows, or use peer2peer software.

When getting mass e-mails, make sure the sender uses BCC.

Do not publish your e-mail in the open on forums.

Keep your Java and Flash up to date through Oracle and Adobe website (do not use the updater windows that popup from time to time).

When using WiFi use 802.11g or better with WPA2 encryption, and WiFi ethernet bridges for those machines that only support 802.11b (Apple's original Airport).

And make sure your Apple menu -> System preferences -> sharing firewall is turned on, with all the checkboxes unchecked except when you need them.

Norton Antivirus (made by Symantec) has a very long and illustrious reputation for mangling Mac OS X systems, sometimes to the point where a complete reinstall is necessary. Among other things, it installs kernel extensions which are known to cause kernel panics and system freezes; it contains known and documented bugs which can silently corrupt Adobe Photoshop and Adobe InDesign files, destroy a user's ability to authenticate as an administrator, and (on PPC systems) can cause Classic to stop functioning; and Symantec has on at least two occasions now released flawed .dat file updates which erroneously report certain critical Mac OS X files as "viruses." (Deleting these "viruses" causes damage to the system that in some cases renders it unbootable.)

You have gotten excellent feedback from two experienced users.

Short answer, NO.

Not Norton, never. But depends which OS and Mac. Running an AV like Sophoson 10.6 Snow Leopard right now, since it looks like Apple has probably abandoned it, might not be a bad idea.

And might not even be a bad idea on any of the more recent OSs, as Apple is kind of lackadaisical in getting out security patches and XProtectupdates in a timely fashion.

I'm running it both on Snow and Mountain Lion, with no adverse affects.

But you do need to reaize that it will not make you bullet proof. You will still need to practice good browsing and security habits and keep everything updated.

No need for any security for your mac, If you want thn you have a no need to pay anything you can donwload this Free Antivirus for your mac:-
