How to Use the Farbar Recovery Scan Tool (FRST)

The Farbar Recovery Scan Tool (FRST), often just called FRST, is a powerful and free diagnostic tool used to identify and troubleshoot issues on Windows computers. Understanding how to use the Farbar Recovery Scan Tool is crucial for diagnosing and fixing various computer problems, from malware infections to system instability. This guide will walk you through the process, ensuring you can effectively utilize this valuable tool.

What is FRST and Why Use It?

FRST is a portable application, meaning it doesn’t require installation. It scans your system for various issues, including malware, PUPs (Potentially Unwanted Programs), and system inconsistencies. The scan results are then saved in text files (FRST.txt and Addition.txt) which can be analyzed to pinpoint the problem. Unlike many other diagnostic tools, FRST provides detailed information about your system, enabling advanced troubleshooting.

Downloading FRST Safely

Downloading FRST from a reputable source is paramount. Always download it directly from a trusted security forum or website. Avoid downloading from unofficial sources, as modified versions could contain malware.

Download FRST: Download the correct version (32-bit or 64-bit) based on your operating system.
Extract the Files: Extract the downloaded zip file to a dedicated folder on your desktop.
Run FRST: Right-click on “FRST” or “FRST64” (depending on your system) and select “Run as administrator”.

Wait for Completion: The scan may take several minutes. Avoid using your computer during the scan.
Analyze the Results: After completion, two text files (FRST.txt and Addition.txt) will be generated in the same folder.

Understanding the FRST Logs

The FRST logs contain valuable information about your system. Understanding how to interpret these logs is crucial for effective troubleshooting. The logs include details about running processes, services, drivers, registry entries, and more. Look for entries highlighted in red or yellow, as these often indicate potential issues.

Using FRST with FixList: Advanced Troubleshooting

For more advanced troubleshooting, FRST can be used in conjunction with a FixList. A FixList is a custom script that instructs FRST to perform specific actions, such as removing malware or fixing system errors. FixLists should only be created and used under the guidance of a trained security expert.
