Applies to:
  • Kaspersky PURE R2
  • Kaspersky PURE
  • 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:

    Method 1. Uninstallation of ESET security product by standard Microsoft Windows tools

    • in the left lower corner of the screen click Start
    • select the All Programs menu item
    • select ESET - ESET Nod32 Antivirus from the menu that will open
    • select Remove
    • follow the Setup Wizard instructions and remove the application
    • after the uninstallation process completes, restart your computer
    • after restarting, confirm that you can see hidden files and folders
    • delete the following folders:
      • if OS Windows XP is installed on your computer
        • C:\Program Files\ESET
        • C:\Documents and Settings\All Users\Application Data\ESET
        • C:\Documents and Settings\[user_name]\Application Data\ESET
      • if OS Windows 7 or Vista is installed on your computer:
        • C:\Program Files\ESET
        • C:\ProgramData\ESET

    Try to install Kaspersky PUREKaspersky PURE R2 once again.

    If the Setup Wizard informs you that the ESET software incompatible with Kaspersky Lab applications is detected, remove the application using ESET Uninstaller.

    Method 2. Uninstallation of ESET security product using ESET Uninstaller 

    WarningUsing the ESET Uninstaller may reset your Windows network settings (alternative IP address, default gateway, subnet mask). After you complete work with ESET Uninstaller and restart your computer, you will need to configure network settings.

    In order to uninstall the ESET security product using ESET Uninstaller, perform the following actions:

Please keep in mind that as soon as this application is finished your network connection can be down and you will have to restart your PC. Are you really sure to continue? <y/n>". If you agree to perform the actions type "y" to confirm and press Enter
