Norton antivirus updates features a new Automated Support Assistant which determines which Symantec products and versions you have and checks to see whether you need updates
|
This feature will search for a valid subscription to virus definitions before it installs any updates you have downloaded. Be sure to check the expiration date of your subscription to Symantec. If it has expired, you must renew your subscription before you will be allowed to install the definitions.
You can renew your subscription by running LiveUpdate from within Norton AntiVirus.
After installation, Norton antivirus updates are initiated by using LiveUpdate. The first LiveUpdate does require your attention, unlike those in other antivirus products such as Panda Antivirus and PC-cillin.
Also you will find the 2.6MB download takes a long time over a dial-up connection. The good news is that subsequent definition updates are much quicker and automated.
Norton antivirus updates are simple and straight forward. Even beginners can easily run manual scans or updates. You will always know where you are as the main screen always shows the last full scan, update, and subscription dates.
If you are unsure of what to do next, you can simply consult the manual. Context-sensitive help clearly explains even advanced items, such as recommending settings for the best protection and Bloodhound heuristics.
All your settings can be password-protected.Norton AntiVirus updates include both antivirus protection and a simple firewall (new in the 2005 version).
A new Preinstall Scan circumvents infections that attempt to prevent Norton antivirus installation. It automatically downloads and installs virus signature updates and can run a quick scan of vulnerable files immediately afterward.
The new Internet Worm Protection feature gives added security to those not using a firewall.
Use of free-spyware-removal software can prevent the installation of keyboard spying software that looks for credit card and other identifying information that can lead to identity theft.
