Kaspersky Internet Security 2012

In some cases after you have uninstalled ESET Nod 32 using the standard means of your operating system and then rebooting your computer, some signatures about the antivirus software may remain in the system registry of your operating system. If ESET Nod32 is detected, Kaspersky Lab Setup Wizard asks to delete the detected incompatible software manually and terminates the installation process.

Before the files are copied onto a hard disk the Setup Wizard scans the disk for software incompatible with Kaspersky Lab applications. Signatures in the system registry are determined by Kaspersky Lab Setup Wizard as if fully-functioning ESET Nod32 is installed on your computer.

In order to fully remove the product from your computer, follow the recommendations below.

The ESET Nod32 can be uninstalled by two different methods:
