The 2007 version includes the new Security History feature to let you review detections and other actions taken by Norton AntiVirus. Also new for this release is Cookie Tracking Support, which gives you the ability to remove detected tracking cookies.

The improved user interface in AntiVirus 2007 contains a convenient, centralized location where you can review detections, items repaired, and action required. View larger.

The new Security History is a convenient, centralized location where you can review detections and other actions taken by Norton AntiVirus. AntiVirus 2007 continues to offer Auto-Protect, Worm Blocking and more alerts. It also provides the option to allow Norton AntiVirus to automatically take action or be alerted prior to taking action. This "set-it-and-forget-it" solution lets you view alerts when you want to, so you can let Norton AntiVirus take care of the rest. At your convenience you can visit the Security History to view detections made and actions already taken by Norton AntiVirus.

Tracking Cookie Support is also new for AntiVirus 2007. Upon scanning the system, tracking cookies will be detected and you will have the option to delete tracking cookies or ignore them. For some sites, you may want to allow cookies so that you don't need to sign into the site each time you visit it. But other cookies you may want to delete, such as those from third-party advertisers.

Internet Worm Protection has been enhanced for 2007 so that it now protects against entire categories of spyware, viruses, worms and Trojan horse programs. Rather than block individually identified threats, this feature now matches individual but unknown threats to known worm and virus families and blocks them from installing on the system without requiring specific virus or worm signatures, giving you zero-hour protection. This technology helps protects against new spyware, viruses and worm threats before they are even created.

Rootkit protection has been improved for AntiVirus 2007 to better guard against hidden threats such as rootkits, a type of virus that exhibits no discernible symptoms in order to evade detection. Previous versions of Norton AntiVirus already protect against user mode and application level rootkits. Leveraging VxMS technology acquired by Symantec through its merger with Veritas, Symantec has increased detection of emerging stealth threats by including patent-pending rootkit protection at the deepest level within the operating system. This protects against kernel mode rootkits that have dropped a driver onto the system. These threats may be invisible to Windows or other security software, but can be detected and removed by AntiVirus 2007.

Norton AntiVirus protects your computer with three distinct types of scans.

• The Preinstall Scan detects and cleans spyware, viruses and worms on an already infected system. The enhanced pre-install scan now detects and removes high-risk spyware before AntiVirus is even installed.
• QuickScan runs invisibly after you receive new virus definitions from Norton. QuickScan helps ensure that your computer is fully protected against even the newest threats. QuickScan has now expanded to search for other areas on the system such as "My Documents" and other areas of common infection.
• Full Scan is a full-system scan that now includes a foreground and background throttling mode. The background throttling mode performs the scan using less processing power so users can continue working on their system without major performance impacts.

The Norton Protection Center has been completely redesigned to communicate security status simply and efficiently. You can browse easily through each drop-down category to view the status of the category's security features. Overall computer status is always visible via the Norton Status icon on the taskbar or in the Windows system tray icon.

The improved Auto Protect Blocking detects and blocks incoming viruses, spyware and unwanted adware threats as they attempt to install and execute on your system. Auto Protect Blocking now blocks both threats and high security risks from ever installing on the system. It is always running invisibly in the background to protect your computers. The easy "install and forget" feature keeps you from having to make constant security decisions to keep your computer safe and protected.

Packer support has also been updated for 2007 to protect against virus hidden in compressed files or other masking technology. Many virus writers use packer tools to package up a virus such that the virus becomes difficult to detect. Sympack will now focus on unpacking the virus so that it can be detected.
