Q1: Please Choose Your ESET Product:

Antivirus Scan Failed

ESET antivirus displays scan options when you insert a removable media device into your computer, and you will be prompted to take any actions. It is a good antivirus, but not perfect. Sometimes the antivirus may stop working, or the scan may take too long. Many factors can cause scan failure.  And because of it, the viruses and malware on your device can go undetected. Read the below content to learn about the possible causes and the ways to fix them.


  • The app was not properly installed: If the ESET antivirus is not installed on your computer, it may not work properly.
  • Another third-party antivirus: If, along with ESET, you are running another third-party antivirus, then it might interfere with the ESET antivirus scanning process.
  • Firewall restriction: The firewall restriction can be a reason for your ESET scan failure.

  2. Click Computer scan, head to Advanced scans, and choose Custom scan from the drop-down menu.
  3. From the drop-down menu, choose "In-depth scan." Select the check box next to This PC or PC and click Scan.

If the ESET antivirus software finds any malicious file or program, it quarantines it. To restore or delete a quarantined file, follow the steps below.
  1. Open the ESET main program window to access the file quarantined by ESET.

  3. Click Quarantine and select the file that you want to restore or delete.

The Smart Scan is ESET’s default advanced scanning profile. It uses Smart Optimisation technology, which excludes files that got a clean bill of health during the previous scan and have not been modified since then. It reduces scan times and has a minimal impact on system performance. At the same time, an in-depth scan does not exclude any file during the scanning process.

ThreatSense Parameters is an advanced scanning option that lets the user define the types of files examined by the scanner, the method used to examine files, and the default action to take if a threat is detected during scanning. ThreatSense parameters are divided into the following categories: objects to scan, scan options, cleaning, exclusions, other, and limits.
