Eset NOD32 Antivirus 5

ESET's NOD32 Antivirus 5 is ideal for PC users who value speed, performance efficiency and protection efficacy in their computer security applications. It has certainly created a name as among the best antivirus products in the market and has been consistently in the Top Ten in PC Magazine’s line for this year, though at the tail end.


The feature package of ESET NOD32 Antivirus 5 leaves out useless fat that only highlights its overall scanning, detection and removal efficiency and efficacy against all the known virus, Trojans, bots, rootkits, and other malware. It uses its proprietary ThreatSense algorithm, hailed in the industry as among the best proactive heuristic detection technology in the industry.

But that doesn’t mean ESET NOD32 Antivirus 5 has abandoned the traditional virus signature updating. It still does as part of its protection arsenal. Needless to say, automatic updating is comprehensive but behind the scenes so you can feel safe using your PC knowing you have a competent antivirus program working in the background.

NOD32 Antivirus 5 offers multilayer protection for real-time email scanning, rootkit and spyware scanning. Online protection is among its better strengths. Malware from known malicious sites are blocked, alerting you of any frustrated attempt made through your browser online. URL level blocking and malicious file detection is average with an 81% success rate in independent lab tests. Its email scanning facility goes into action unobtrusively as it is integrated with POP3 email clients and MS Outlook, if you are using those.

The program has other tools like ESET's SysInspector which can be handy when you have to share PC performance data with its technical support team. It tracks changes to your system and takes snapshots at different times so you can see what has changed, was removed or added to your system in diagnosing a performance degradation.

Installation and setup

Installing NOD32 Antivirus 5 is a breeze either as a shrink-wrapped CD or a downloaded installer. But it is quite aggressive in requiring that no program is running in your PC when installing as certain component files may conflict with those that are running. It can install in Safe Mode and this is recommended if your PC is already suffering an infection. After installation, you can run its wizard for creating a rescue CD but this won't work unless you have Microsoft's Automated Installation Kit (AIK) installed.

The program can be installed even without being online, but establishing an Internet connection is recommended to enable you to benefit from what ESET can offer from its online access when installing.

Eset stands behind its products and if you have any installation or usage problem, ESET NOD32 Antivirus 5 has not only has its in-product guide downloadable, you can also access its online help tools, community forums and technical support via email.

User Interface

Considered a winning feature for Esset Nod32 Antivirus 5 is its elegantly simple user interface that hides unnecessary complexity. Using a simple white background, the program continues to sport an intuitive graphical interface for its standard and advanced versions.

The left column side of the main page neatly lays out quick icon shortcuts to its major functions as Home, Computer Scan, Update, Setup, Tools, and Help and Support. The right main window pane presents the information for each selection icon. Using the advanced version gives you a toolbar at the top of the windows so you readily access its configuration setting

Eset NOD32 3.0

ESET's NOD32 3.0 is ideal for users who value speed AND effectivity in their computer applications. This software product has a light footprint and conducts fast scans - qualities that are hard to find in the numerous anti-virus software programs being sold today.

NOD32 3.0 also boasts of the ESET's ThreatSense technology, which enables a more proactive virus detection and is hailed as one of the best heuristic programs to date.


The NOD32 3.0 sports an improved version of ESET's ThreatSense technology, which is a patented scanning engine that combines heuristic detection of new and unknown malware with signature detection of known malware.

Compared with other anti-virus programs that rely on signature updates to detect viruses and worms, ESET's ThreatSense technology is able to analyze and decode executable codes and identify evolving threats such as bots, rootkits, and trojans.

The ThreatSense technology is effective in providing protection against constantly evolving threats that other scanning technologies do not detect.

Another cool feature of the NOD32 3.0 is that it allows users to either push the scan into background or toggle the scan window to the forefront while it's scanning. This means that you can still browse and work on your documents without the scan window getting in your way. The NOD32 3.0 version also sports a new user interface and has more customization options to speed up the scanning process.

NOD32 3.0 provides several layers of protection that includes anti-virus protection, real-time email scanning, rootkit scanner, and anti-spyware protection. The software's email scanner is easy to use because it can be directly integrated into MS Outlook and other POP3 email clients.

One of the downsides to the product is that it lacks the Parental Control option, which enables parents to control and block the sites their kids can visit online.

NOD32 also automatically removes threats, which can be quite problematic especially if there are certain components you need for a game or program. The good news is that you can change these settings by right-clicking on the quarantined selection and restoring the items removed.

Installation and setup

To install NOD32 3.0, you will need to first close all running programs and uninstall any other anti-virus programs you have stored in your computer. This is because some components of NOD32 3.0 may conflict with the ones used by other programs and cause the NOD32 3.0 to slow down or become less effective.

The software can be installed even without an Internet connection, but ESET recommends establishing an Internet connection during the installation process so that you can take full advantage of what the program has to offer.

NOD32 3.0 provides users with two installation options: via the installation CD or by downloading the NOD32 3.0 file, which can be found on the company's website. Once the installation process is complete, ESET NOD32 Anti-Virus will start automatically. And unlike most anti-virus programs thatrequires a system reboot before it can be used, ESET NOD32 3.0 works right away and runs in the background while you continue working on your computer.

NOD32 3.0 is one of the very few anti-virus software products that still support Windows 2000, Windows XP, and Windows Vista.

User Interface

The Version 3.0 sports an intuitive and user-friendly interface that comes in two versions: standard and advanced. At the left side of the interface, you'll find quick shortcuts to the following sections: Computer Scan, Protection Status, Update, Setup, Tools (in the advanced interface version), and Help.

The right window pane, on the other hand, presents information and updates on the specific feature currently in use. If you choose the advanced interface version, you'll also find a toolbar at the top part of the window where you can easily access and tweak advanced configuration settings.
