Typically, a computer running a full-on firewall won't respond to pings. Even with Worm Protection, Norton users will still need a firewall. Like its predecessor, Norton AntiVirus scans for hidden spyware threats, including adware, dialers, and keystroke loggers that record every key you tap.
Unfortunately, its real-time scanner doesn't detect spyware; rather, Norton spots these menaces during only a full system scan or a Quick Scan, the latter of which runs immediately after virus-definition downloads. Overall scanning speed was respectable.
In our informal tests, Norton took 37 minutes to scan a 12GB partition. We did not run the office productivity portion of the benchmark because it incorporates McAfee VirusScan 5.
With Norton AntiVirus running, our test system scored 94 percent--meaning a 6 percent reduction in overall system speed. By comparison, McAfee also scored a An Internet-content-creation score of represents the performance of our test system without any extraneous software running. In a test of scanning speed, Norton AntiVirus took an average of 6. Norton AntiVirus has been tested on Windows desktop systems 10 times since November by the independent testing organization VirusBulletin and earned its coveted VB Percent title each time.
Symantec's help site also includes the Automated Support Assistant, a downloadable utility that scans Norton AntiVirus for known problems. However, the assistant needs more tooling. For example, when we disabled Auto-Protect, Norton's real-time virus scanner, the Automated Support Assistant reported no irregularities on our system--oops. Symantec also offers e-mail support, but you'll need to run the Automated Support Assistant before firing off a query.
The Good New inbound port blocking to prevent worm intrusions; faster preinstallation scans; improved interface. Doesn't include a full-fledged firewall; real-time scanner doesn't look for spyware.
Norton AntiVirus is a tenacious virus fighter that, given its premium price, should also--but doesn't--include a firewall. It's a good bet for Norton users who want to upgrade, though. Norton AntiVirus offers both antivirus protection and new in this version a simple firewall. It automatically and silently downloads and installs virus signature updates and can run a quick scan of vulnerable files immediately afterward.
By default NAV blocks spyware, adware, and other malicious nonvirus applications. It scans e-mail going in and out of the system as well as IM file transfers. In the latest study from AV-Test. NAV's Internet Worm Protection feature blocks unsolicited inbound data packets just like Windows Firewall which it replaces by default. It specifically blocks known Trojans and temporarily prevents all connections from any IP address that attempts illicit access.
It does not attempt to block multiple e-mails sent in a short period, but it does watch for programs attempting to e-mail themselves as attachments. Under its default settings, detection of a virus halts all e-mail processing until the user responds. We quickly changed the settings to have the program fix problems automatically, but the program does include an option to prevent the e-mail program from timing out when it's waiting for a response.
On our test system, NAV found over threats in a set of 2, messages. All but a handful, however, had already been neutralized by a server-side antivirus package. It can also filter file transfers through Yahoo! Messenger and MSN Messenger.
NAV keeps a detailed log of all blocked threats, each with a link to a detailed description on Symantec's Security Response Web site and an indication of the threat's disposition. It also reports on a variety of other security events, including incoming and outgoing connections, with IP address, port used, bytes sent, and duration.
