ESET NOD32 Antivirus has a feature called Self Defense that prevents viruses from disabling the program's features. It can also detect when malware is trying to corrupt the antivirus program's files and takes action to protect your computer. Self Defense can interfere when you try to update the program or want to temporarily disable its virus scanning features. If you're having difficulties updating or disabling NOD32, you can disable Self Defense in a few simple steps.

Skill level:
Moderately Easy


  1. 1

    Double-click the blue "NOD32" icon in the Windows notification tray to open the program's interface. Press your keyboard's "F5" key to open the program's advanced settings window.

  2. 2

    Clear the box beside "Enable Self-Defense" under "Antivirus and Antispyware Protection." Click "OK" when prompted that you need to restart your computer to successfully disable the feature.

  3. 3

    Click "OK" near the bottom of the window; then type your Windows administrator password if prompted. Click the "Start" button, click the right arrow next to "Shut Down," and select "Restart" to reboot your computer. NOD32 then loads in the future without its Self-Defense feature.

Tips and warnings

  • To keep your computer secure, you should re-enable Self Defense as soon as possible.
