Norton AntiVirus 2002 provided stellar performance on a P4 with 256Mb of RAM and over 20Gb of available hard disk storage. Conversely, on a P3 with 64Mb of RAM and less than 100Mb of available hard disk storage (after installation), adverse performance impact was quite noticeable. If your system can handle it, Norton provides very good protection.

On Tuesday, Symantec admitted that all versions of Norton Anti-Virus (NAV) contain a security vulnerability that could allow a malicious user to remotely take control of the computer. This kind of announcement is common to Windows users but this flaw also affects NAV running on Apple's OS X platform.

It is essential that you first uninstall all existing anti-virus applications from your computer, including Norton, before you install McAfee VirusScan Enterprise edition, which is required for ALL Windows computers at BC.

Every year, I take a look at the latest crop of antivirus software. Usually, the new versions of these programs are just the same software packages in a new box with the current year on it. This year, however, I saw a demo for an application that had me running home to install it and raving about it to friends and family. Trend Micro's PC-cillin Internet Security 12 (2005) is the best antivirus software package I've seen in a long while. Give it a try; I think you'll agree.

In fact, Norton has been coasting on old code for several years, simply dressing it up with an occasional new feature here and there. This year, Norton AntiVirus 2005 adds a limited firewall designed to block incoming worm code. I say, why not give us a full firewall instead? No, for that, you'll need to cough up another £44.99 for Norton Personal Firewall or go whole hog and get the £59.99 Norton Internet Security suite. Norton AntiVirus 2005 produces a perceptible resource drain -- you'd think they'd have fixed that by now. Worse, in order to completely remove Norton AntiVirus from your PC, you'll need to download a free tool from Symantec (follow the links in the 'Norton AntiVirus installed as a stand-alone product' section of the page).

When I see the annual updates for their antivirus programs, I'm always quick to ask: why should anyone update? In the case of Norton, Symantec requires an upgrade. Signature-file updates are available for only two years after a product's release.

Wait for the autorun feature to load the splash (startup) screen. If you have autorun disabled then click through the Start menu to the "My Computer" button, right-click on the optical drive containing the Norton disc, then click "Explore." From here simply double click the "Setup" executable file.

An error occurring in the update of Norton's virus database on Friday has caused millions of PCs and computers to crash-a heavy blow to people's daily work and ongoing business.
