Norton Internet Security 2006 debuted on September 26, 2005.<ref>{{cite web |author=Gregg Keizer |url=http://www.crn.com/it-channel/171200920;jsessionid=JD0IMZWH0GBLWQSNDLPCKH0CJUNN2JVN |archive-url=https://archive.today/20120731053329/http://www.crn.com/it-channel/171200920;jsessionid=JD0IMZWH0GBLWQSNDLPCKH0CJUNN2JVN |url-status=dead |archive-date=July 31, 2012 |title=Symantec Updates Small-Biz, Personal Security Software |publisher=ChannelWeb |date=September 26, 2005 |access-date=February 23, 2009 }}</ref> The new main interface, the ''Norton Protection Center'', aggregates all information in a central location. Security status was shown by how secure the computer was for tasks such as e-mail and Internet browsing, not in the context of which features were enabled. The ''Protection Center'' could recognize third-party software protecting the computer. The new interface advertises additional products from Symantec; some categories of protection, such as "Data Protection", will read "No Coverage" until the user purchases and installs [[Norton SystemWorks]]. An additional [[system tray]] icon was created by the ''Protection Center''.

The installation was noted as lengthy by ''PC Magazine'', especially on malware-infected systems. Spyware detection has been tweaked since the last release. It has been updated to better identify keyloggers. In ''PC Magazine'' testing, Norton successfully detected all 11 spyware threats and removed all but two. ''PC Magazine'' did give Norton credit even when manual removal was required. The suite removed three of four commercial keyloggers. When attempting to install the spyware on a clean system, Norton blocked all 11 and two of the four commercial keyloggers. In most cases, it did not block the installation, however Norton did call for a scan after the spyware was installed. In ''PC Pro'' testing, Norton detected 78 percent of spyware, removed 82 percent, and blocked 65 percent from installing.

Norton AntiSpam was discontinued as a separate product from Symantec, now only available in Norton Internet Security. The feature could block all e-mail from unknown senders, and automatically blocks messages with suspicious elements such as invisible text, HTML forms, and phishing URLs. To improve accuracy, Norton analyzes outgoing e-mails and messages whose categorization was corrected by users by hitting the "This is spam" and "This is not spam" buttons. In ''PC Magazine'' testing, the feature marked one in ten valid e-mail as spam and let one in every six spam messages in the inbox. 400 messages were used, and the program was allowed to process the messages for over a week. In ''PC Pro'' testing, the feature performed better, blocking 96 percent of spam, with a false positive rate of 0.2 percent.

Norton recommends disabling the [[Windows Firewall]] to avoid redundant alerts. The firewall stealthed all significant ports in ''PC Magazine'' testing. Attacking the firewall itself was unsuccessful, and ''PC Magazine'' was unable to stop its [[Windows service|service]], terminate its process, or disable the firewall using simulated mouse clicks. The firewall passed ''PC Pro''{{'}}s tests, successfully stealthing all ports.

Other features included Bloodhound technology, which looks for virus-like behavior to better find [[zero day virus]]es. The ''Security Inspector'' looks for common vulnerabilities, including insecure user account passwords and browser insecurities. Advertisement blocking rewrites a website's [[HTML]] to prevent advertisements from being displayed. Parental controls, an optional component, could block certain programs from accessing the [[Internet]], such as IM clients, and restrict [[Usenet newsgroup|newsgroup]] access. Restrictions could be assigned to different Windows users accounts. Sites were classified in 31 categories, and the four profiles which could be assigned each block different categories of sites. Supervisors define exceptions, add global blocked sites, or block all access to sites not on a user-created whitelist. Both ''PC Magazine'' and ''PC Pro'' noted the exclusion of time-based restrictions.<ref name="PCMAG">{{Cite news|url=https://www.pcmag.com/article2/0,2817,1912816,00.asp |title=Norton Internet Security 2006 |publisher=[[PC Magazine]]|access-date=28 November 2017|first=Neil J. |last=Rubenking}}</ref> Information filtering could be controlled on a per-user basis.

[[Windows 98]] compatibility was dropped from this release.
