How do I run the Win32/Necurs cleaner?

Issue

  • Unable to install ESET products
  • ESET is not functioning or is giving error messages
  • Error communicating with EKRN
  • Analysis of application protocols (POP3, HTTP) will not function
  • Your ESET product detects the threat Win32/TrojanDownloader.Necurs.A

Details

The Win32/Necurs infection is designed to deny read access to malicious files and is able to run at the kernel level. As a result, this particular malware can sometimes go undetected on a computer running ESET products.

Solution

I. Run the ESETNecursCleaner tool

  1. Download and save the .exe file to your Desktop (or your default "Downloads" directory) by clicking the following link:

    http://download.eset.com/special/ESETNecursCleaner.exe

     
  2. Double-click ESETNecursCleaner.exe to run the tool. You must click Agree to agree to the End User License Agreement the first time that you use the tool.
  1. If you receive the message "Threat not found—You don't have Win/32Necurs in your system" your computer is not infected with Necurs malware.

    If you receive the message "Win32/Necurs found in your system," press Y to confirm that you want to remove the rootkit.
