I receive the message that my ESET installation ended prematurely

KB Solution ID: SOLN2861|Last Revised: February 13, 2015

Issue

  • If you receive the notification "installation ended prematurely" when upgradeing to ESET Smart Security or ESET NOD32 Antivirus 8, see our Knowledgebase article for instructions.
  • Installation is not successful: "Rolling back action"

Verify that Windows Data Execution Prevention (DEP) is not blocking installation

If you are receiving "ESET Smart Security installation was ended prematurely" immediately when attempting to run the ESET installer file from your Downloads folder, see our related article before attempting the steps below.

Details

A malware or exploit that is removing the Base Filtering Engine service is executing a Windows command (sc delete bfe) which causes the Base Filtering Engine to disappear after a restart. This does not appear to be an issue isolated to Win32/Sirefef but to multiple Rogue Antivirus applications. This is similar to when a Rogue Antivirus executes the attrib command to hide all files.

Solution

I. Run the ESET uninstaller utility to remove partial installations

We recommend that you run the ESET uninstaller utility in Safe Mode with Networking to remove any remnants of previously installed ESET programs or partial installations that might have failed before attempting to install your new ESET product. After removing any previous installations, attempt to install your new ESET product again.

II. Remove any existing antivirus solutions

For the successful installation of ESET products, it is important that no other antivirus products are installed on your computer. Typical uninstallation* using the Windows removal tool (Add/Remove Programs) is often insufficient. See our list of Uninstallers (removal tools) for common Windows antivirus software for assitance removing previously installed software. If you do not know whether there is an antivirus product installed on your system, we recommend that you use the ESET A/V Removal tool to scan your system for these types of programs
