What is HIPS (Host-based Intrusion Prevention System) in ESET Smart Security/NOD32 Antivirus?

KB Solution ID: SOLN2950|Last Revised: September 30, 2014

ESET's Host-based Intrusion Prevention System (HIPS) is included in ESET NOD32 Antivirus and ESET Smart Security 5 and newer versions. HIPS monitors system activity and uses a pre-defined set of rules to recognize suspicious system behavior. When this type of activity is identified, the HIPS self-defense mechanism stops the offending program or process from carrying out potentially harmful activity.

Advanced users

Users can define a custom set of rules to be used instead of the default rule set; however this requires advanced knowledge of applications and operating systems and is not recommended in most situations.

To ensure that HIPS is enabled on your system, follow the step-by-step instructions below:

  1. Open ESET Smart Security or ESET NOD32 Antivirus. How do I open my ESET product?
  2. Click Setup in the main program window. In the Computer section of the Setup module, make sure that you see Enabled next to HIPS (see Figure 1-1). If HIPS has been disabled on your system, click here for instructions on how to re-enable HIPS.
