Creating scan reports in Avast Antivirus

Avast Antivirus allows you to specify whether you want to produce a report automatically at the end of each scan (Core Shields, Predefined Scans, or Custom Scans). When troubleshooting issues with Avast Support representatives, you may be requested to provide this report file. Follow the steps in this article to enable the generation of a scan report, run a scan, and locate the scan report file on your PC.

Generate scan report

  1. Open the Avast Antivirus user interface and go to MenuSettings.
  2. Select Protection in the left menu and click Core Shields.
  3. Scroll down and select the shield for which you want to generate a report.
  4. Ensure the box next to Generate report file is ticked.
  1. Open the Avast Antivirus user interface and go to MenuSettings.
  2. Select Protection in the left menu and click Scans.
  3. Select the scan for which you want to generate a report.
    The boot-time scan does not support customization to the report, and always creates a full report automatically after it is run.
  4. Scroll down and ensure the box next to Generate report file is ticked.
  1. Open the Avast Antivirus user interface and go to ProtectionScans.
  2. Select the Custom scans tile, then click the gear icon next to the relevant scan in the list and select Settings.
  3. In the scan settings window, click the Report file tab.
  4. Ensure the box next to Generate report file is ticked.
  5. Manage the following settings:
    • File name: provide a name for the report file.
    • File type: select the format of the report file - plain text ANSI, plain text Unicode, or XML.
    • If file exists: select Append if you want new results to be added to the end of the previous report, or Overwrite if you want new results to replace the previous report.
  6. Define the contents of the report:
    • Infected items: files and areas of the scanned environment identified as malware. This option is ticked by default.
    • Hard errors: unexpected errors that require further investigation. This option is ticked by default.
    • Soft errors: minor errors, for example, a file that wasn't scanned because it was in use while the scan was running.
    • OK items: files and areas identified as clean. Ticking this option results in very long reports.
    • Skipped items: files and areas not scanned due to exclusions in the scan settings.
  7. Click OK.
