2.1 Typical installation
Typical installation mode provides configuration options appropriate for most users. These settings provide excellent
security, easy setup and high system performance. Typical installation mode is the default option and is recommended
if you do not have the particular requirements for specific settings.
After selecting the installation mode and clicking Next, you will be prompted to configure the ESET Live Grid. The ESET
Live Grid helps to ensure that ESET is immediately and continuously informed about new infiltrations in order to quickly
protect our customers. The system allows you to submit new threats to ESET‘s Virus Lab, where they are analyzed,
processed and added to the virus signature database.
By default, the I agree to participate in ESET Live Grid option is selected, which will activate this feature.
The next step in the installation process is to configure detection of potentially unwanted applications. Potentially
unwanted applications are not necessarily malicious, but can often negatively affect the behavior of your operating
system. See the Potentially unwanted applications chapter for more details.
Select the Enable detection of potentially unwanted applications option to allow ESET NOD32 Antivirus to detect
this type of applications.
The final step in Typical installation mode is to confirm installation by clicking the Install button.
After the installation is completed, you will be prompted to activate your product.

prompted to activate your product. See typical installation for more information about product activation.
2.3 Upgrading to a newer version
Newer versions of ESET NOD32 Antivirus are issued to bring improvements or fix issues that cannot be resolved by
automatically updating of the program modules. Upgrading to a newer version can be accomplished in several ways:
1. Automatically, by means of a program update
Since the program upgrade is distributed to all users and may have impact on certain system configurations, it is
issued after a long testing period to function with all possible system configurations. If you need to upgrade to a
newer version instantly after it has been released, use either of the following methods.
2. Manually, in the main program window by clicking Install/Check in Update > Available version of ESET NOD32
3. Manually, by downloading and installing a new version over the previous one.
At the beginning of installation, you can choose to preserve current program settings by selecting theUse current
settings check box.
2.4 Entering username and password
For optimal functionality, it is important that the program is automatically updated. This is only possible if the correct
username and password are entered in the Update setup.
If you did not enter your username and password after the installation, you can do so now. From the main program
window, click Update, then Product activation... and enter the license data you received with your ESET security
product into the Product activation window.
When typing your Username and Password, it is important to type them exactly as they are written:
- The username and password are case sensitive and the hyphen in the username is necessary.
- The password is ten characters long and all lowercase.
- We do not use the letter L in passwords (use the number one (1) instead).
- A big '0' is the number zero (0), a little 'o' is the lowercase letter o.
We recommend copying and pasting the data from the registration email for maximum accuracy.
2.5 Computer scan
After installing ESET NOD32 Antivirus, you should perform a computer scan to check for malicious code. From the main
program window, click Computer scan and then click Smart scan. For more information about computer scan, see
section Computer scan.
