Farbar Recovery Scan Tool quickly scans and then displays detailed information about the Windows Registry loading points, services, driver services, Netsvcs entries, known DLLs, drives, and partition specifications. It will also list some important system files that could be patched by malware. The report provided is automatically saved as FRST.txt in the same directory as the original download for easy access. It contains a lot of information but is presented in a relatively easy-to-read format.
