Norton Security replaces Norton Internet Security for Mac




      Protects you against against viruses, spyware, software vulnerability attacks and more
      Antiphishing filter detects fraudulent websites to safeguard your identity
      Powerful two-way firewall shields your Mac from hackers
      Confidential File Guard password-protects your important files
      Works with Mac OS® X v10.7 (Lion) and Mac OS® X v10.4.11 - 10.6


Norton Internet Security 5 for Mac® is Symantec’s most complete security offering for Macintosh computers. It includes the online threat protection offered by Norton AntiVirus 12 for Mac as well as strong identity protection features. It also boasts a powerful two-way firewall to keep hackers away and ensure your personal data never leaves your computer without your consent.

This latest release of Norton Internet Security for Mac® actually includes two products: Norton Internet Security 5 for Mac®, which protects Mac OS® X 10.7 (Lion), as well as Norton Internet Security 4 for Mac® which works with Mac OS® X v10.4.11 - 10.6. For the latter, both Intel® and PowerPC® processors are supported.   


If you own a Mac and you frequently connect it to the Internet, then the simple answer is yes. Many people believe Macintosh computers are inherently better protected against online threats than PCs; while this is partly true, Macs are not perfect in this regard:

Simply put, a lot more computers connected to the Internet run on Windows® compared to Mac OS® X. Evidently, programmers writing the code of malicious software to steal people’s identities might as well target as many computers in one pass as possible. This is why Windows®-based computers are more likely to be targeted by viruses and other malware compared to Macs.

However, this does not mean there are no threats capable of doing damage to Mac OS® X-based computers. There is no better proof of this than the recent "Mac Defender" (also known as "Mac Protector") malware infections of millions of Mac® systems.



Norton Internet Security 5 for Mac® adds two core layers of protection on top of what Norton AntiVirus 12 for Mac offers:
Online Threat Protection
  • This is the level of protection offered by Norton AntiVirus 12 for Mac
  • Viruses and spyware on your Mac® are automatically detected and removed. In particular, all your iPhoto® pictures, iTunes® media and iMovie® projects are scanned and protected against online threats.
  • The Software vulnerability protection feature ensures that hackers cannot take advantage of any application "security holes" to install malware on your Mac®, which could allow them to steal your personal information or take control of your system, among other things.
  • Your downloads as well as emails and instant messages attachments are checked for malware so you can communicate safely via iChat® or other means.
  • Your protection is always up-to-date with automatic daily updates, which will never slow down your computer because of their small footprint
Identity and Data Protection
  • Norton Safe Web identifies potentially dangerous websites directly in search engines results, so you know what websites not to visit from there.
  • Should you decide to bypass search engine results, a powerful antiphishing filter can detect whether or not the websites you access are fraudulent. This feature, along with Norton Safe Web, prevents you from submitting personal, sensitive information to cybercriminals who are behind these "fake" websites. 
  • Confidential File Guard password-protects your files so only authorized users can open and view them.
Firewall Protection
  • A two-way firewall shields your Mac® from hackers and ensures your personal data cannot leave your computer without your consent.
  • Control who can connect to your computer and what connected users can do.
  • Control what applications are allowed to connect to the Internet.



Besides adding support for Mac OS® X v10.7 (Lion), this latest iteration of Norton Internet Security for Mac® is now much easier to use: only the necessary information is presented to the user, the various settings are easy to comprehend and the most conservative ones are selected by default; of course, they can easily be tweaked by users.

Don’t assume you are safe from online threats just because you own a Mac®. Get a comprehensive security package to protect your sensitive data and identity: download Norton Internet Security 5 for Mac® today!
