Understanding FRST Fix Mode: A Comprehensive Guide for Automotive Diagnostics

As an automotive repair expert and content creator for vcdstool.com, I understand the critical role diagnostic tools play in modern vehicle maintenance. While our website focuses on vehicle diagnostic tools, understanding broader PC troubleshooting is also essential in today’s interconnected world. This guide delves into the Farbar Recovery Scan Tool (FRST), a powerful utility for analyzing and repairing Windows systems, with a specific focus on its “fix mode.” This in-depth exploration will help you understand FRST logs and effectively utilize them for system recovery.

This article expands on the original documentation of FRST, providing a more detailed and SEO-optimized resource for English-speaking users seeking to understand and use this tool effectively. We will break down each section of the FRST log (FRST.txt), explaining its significance and how it can be used to diagnose and resolve system issues using FRST’s fix capabilities.

Analyzing the FRST.txt Log: A Section-by-Section Breakdown

The FRST.txt log file is the primary output of the Farbar Recovery Scan Tool. It provides a detailed snapshot of your system’s configuration, highlighting potential issues and areas for investigation. Understanding each section of this log is crucial for effective system diagnosis and repair.

Header Analysis: Initial System Information

The header of the FRST.txt log provides vital preliminary information about the system scanned and the scan environment. Let’s dissect each line:

Scan result of Farbar Recovery Scan Tool (FRST) (x64) Version: 13-05-2020 01
Ran by User (administrator) on DESKTOP-3DJ40NK (Dell Inc. Inspiron 7352) (16-05-2020 12:58:02)
Running from C:UsersUserDesktop
Loaded Profiles: User
Platform: Windows 10 Pro Version 1909 18363.836 (X64) Language: English (United States)
Default browser: FF
Boot Mode: Normal

Line 1: FRST Version and Architecture: This line immediately tells you whether the 32-bit (x86) or 64-bit (x64) version of FRST was executed. Crucially, it also displays the FRST version number. An outdated version might lack the latest features and detection capabilities, so ensuring you use the most recent version is vital for accurate scans.
Line 2: User and Permissions: This line reveals the user account that ran FRST and their privileges. “Administrator” indicates the tool was run with elevated permissions, essential for comprehensive system scanning. It also displays the computer name, system manufacturer, and model, aiding in identifying the specific machine being analyzed. The date and timestamp are crucial for verifying the log’s recency, preventing the use of outdated information.
Line 3: Execution Path: This indicates the location from where FRST was launched. Knowing the execution path can be relevant for fix instructions, especially if FRST wasn’t run from the standard Desktop location.
Line 4: Loaded Profiles: This line lists the user profiles currently loaded on the system. This is important because FRST scans registry hives associated with loaded profiles. In scenarios with multiple users logged in via “Switch user,” all loaded profiles will be listed, along with their respective registry entries. Unloaded accounts are not listed but their ntuser.dat hives are automatically mounted for registry scanning.
Line 5: Windows Edition and Language: This line specifies the Windows edition (e.g., Windows 10 Pro), version, build number, and system language. This is critical for identifying potential update issues. Outdated operating systems or significant update gaps can expose systems to vulnerabilities.
Line 6: Default Browser: This line indicates the system’s default web browser. This information can be useful in troubleshooting browser-related issues or malware that targets specific browsers.
Line 7: Boot Mode: This line shows the boot mode – typically “Normal.” Other modes like “Safe Mode” would be indicated here, which is relevant in troubleshooting boot problems.
Tutorial Link: Following the boot mode, a line provides a direct link to the FRST tutorial, offering immediate access to further documentation and guidance.

Header Alerts:

The header can also display alerts indicating critical system issues:

“ATTENTION: Could not load system hive”: This critical alert signifies a missing system hive, often indicative of severe system corruption or boot failures. The log suggests using LastRegBack: (discussed later) as a potential solution.
“Default: Controlset001”: This notification specifies the default Control Set (CS) used by the system during boot. While usually not needed, it becomes important for advanced troubleshooting involving manual manipulation of the Control Set that Windows loads upon startup. Modifying non-default Control Sets has no impact on the running system.

Processes Section: Analyzing Running Applications

The “Processes” section lists the processes running on the system at the time of the scan. This section can be invaluable for identifying suspicious or unwanted programs.

(cmd.exe ->) (Microsoft Windows -> Microsoft Corporation) C:WindowsSystem32WindowsPowerShellv1.0powershell.exe
(Mozilla Corporation -> Mozilla Corporation) C:Program FilesMozilla Firefoxfirefox.exe

Process Hierarchy: The (parent process ->) notation indicates process relationships, showing which process launched another. This helps trace the origin of processes, which is crucial in malware analysis.
Process Instances: The attached at the end of line notation (not shown in the example but described in the original text) would indicate multiple instances of the same process running.

Using the Processes Section for Fixes:

Stopping Legitimate Processes: You might need to temporarily stop legitimate processes that interfere with a fix or removal process. To do this, copy the relevant process line from the FRST log and include it in your fix script (Fixlog.txt). FRST will attempt to close the process.
Stopping and Removing Malicious Processes: To stop a malicious process and remove its associated files, you need to include both the process line (to stop it) and the file path (to remove it) in your fix script as separate lines.

Registry Section: Managing Registry Entries

The “Registry” section in the FRST log is critical for identifying and correcting issues related to registry keys and values. FRST’s “fix mode” provides powerful capabilities for manipulating the registry based on log entries.

FRST can perform two primary actions on registry entries listed in the fix script:

Restoring Default Values: For specific critical registry entries related to system startup and security (BootExecute, Winlogon values, LSA, AppInit_DLLs), including them in the fix script will instruct FRST to restore the default Windows values. For example, in AppInit_DLLs, FRST can remove a single malicious path without affecting other valid entries.
Deleting Keys and Values: For most other registry entries listed in the FRST log (Run, RunOnce, Image File Execution Options, etc.), including them in the fix script will instruct FRST to delete those keys or values. FRST’s deletion routine is robust, capable of handling permissions issues and embedded null characters. Keys resistant to immediate deletion due to access denied are scheduled for deletion upon system reboot. Only keys protected by kernel drivers will resist deletion and require removal or disabling of the protecting driver first.

Important Notes on Registry Fixes:

File System Independence: FRST registry fixes only affect the registry. They do not automatically remove files that registry keys might load or execute. You must list files for removal separately in the fix script using their full paths.
Startup Folder Items: When dealing with startup items (shortcuts or executables in the Startup folder), FRST lists both the shortcut (Startup:) and its target (ShortcutTarget:). To remove both, you must include both lines in your fix script. Removing only the target executable will leave a broken shortcut in the Startup folder, potentially causing errors on subsequent startups.
Untrusted Certificates and Software Restriction Policies: FRST can detect malware that abuses Untrusted Certificates or Software Restriction Policies to block security software. If such entries are listed, including them in the fix script will revert these restrictions, potentially unblocking security programs. Be aware that Software Restriction Policy detection can sometimes flag legitimate entries, so careful review is necessary.
Group Policy Objects (GPOs): FRST detects Group Policy Objects (Registry.pol and Scripts) that malware can misuse. It specifically identifies Windows Defender, Firefox, Chrome, and Edge policies. Generic notifications are given for other policies and scripts. Including these “GroupPolicy:” lines in the fix script will reset these policies. FRST prunes GroupPolicy folders and typically requires a reboot to fully apply the changes. The detection is geared towards standard home computer setups and might flag legitimate custom policies configured via gpedit.msc.

Scheduled Tasks Section: Managing Automated Tasks

The “Scheduled Tasks” section lists tasks configured to run automatically on the system. Malware often uses scheduled tasks for persistence.

Task: {A0DC62F9-8007-4B9C-AAA2-0AB779246E27} – System32Taskscsrss => C:Windowsrsscsrss.exe [4925952 2019-03-19] () [File not signed]

Including a scheduled task entry from the FRST log in the fix script will remove the task. FRST removes the registry entries associated with the task and moves the task file itself. Crucially, it does not remove the executable that the task runs. If the executable is malicious, it must be removed separately by adding its path to the fix script.

Important Note on Scheduled Tasks: Malware can utilize legitimate executables (like sc.exe) to run malicious files via scheduled tasks. Therefore, always examine the executable path of a scheduled task to determine if it is legitimate before taking action.

Unlocked Tasks: The message "{Random GUID} => key was unlocked" indicates FRST automatically corrected broken permissions on a task during the scan. A new FRST log should be generated to verify if the unlocked task is now visible (if it’s a custom task) or remains hidden (if it’s a whitelisted Microsoft task). If needed, the standard task line can then be included in the fix script for removal.

Internet Section: Analyzing Network Settings

The “Internet” section of the FRST log covers various internet-related settings that malware often manipulates.

Winsock:

Catalog5 and Catalog9 Entries: FRST can identify issues with Winsock Catalog5 and Catalog9 entries, which are critical for internet connectivity. For hijacked default Catalog5 entries, FRST can restore the defaults when the entry is included in the fix script. For custom Catalog5 entries, FRST removes them and re-numbers the remaining entries. For Catalog9 issues, using the cmd: netsh winsock reset command in the fix script is generally recommended. If custom Catalog9 entries persist after the reset, they can be listed in the fix script for removal. Caution: Incorrect Winsock fixes can break internet connectivity.
Broken Internet Access: FRST logs will indicate broken internet access due to missing Winsock entries with messages like Winsock: -> Catalog5 - Broken internet access due to missing entry. or Winsock: -> Catalog9 - Broken internet access due to missing entry. Including these entries in the fix script can attempt to repair the Winsock configuration.

Hosts File:

Custom Hosts Entries: If the Hosts file contains custom entries (beyond the standard localhost entries), FRST will report Hosts: There are more than one entry in Hosts. See Hosts section of Addition.txt.
Resetting Hosts: To reset the Hosts file to its default state, simply copy and paste the Hosts: line into the fix script. FRST will reset the file and confirm this action in the Fixlog.txt.

Tcpip and Other Entries:

Deletion upon Fix: Entries related to Tcpip and other network settings in this section, when included in the fix script, will be deleted from the registry.

StartMenuInternet:

Hijacking Detection: FRST whitelists default StartMenuInternet entries. If an entry appears in the FRST log, it indicates a non-default path, suggesting potential hijacking. Further investigation is needed to confirm if there’s an actual issue. If a problem is confirmed, including the entry in the fix script will restore the default registry entry.

Extensions with Update URLs:

Unofficial Extensions: FRST detects browser extensions (Chrome, Firefox, Edge, Opera) that are not installed through official browser repositories and have update URLs. This can indicate potentially unwanted extensions.

Browser Sections: Edge, Firefox, Chrome, and Chromium-based Browsers

FRST provides dedicated sections for analyzing settings and extensions in popular web browsers.

Edge (Classic and Chromium-based):

Classic Edge: Except for DownloadDir, most lines from the Classic Edge section can be included in the fix script for deletion.
Chromium-based Edge: Follows the same rules as Google Chrome (described below).

Firefox:

Profile Detection: FRST lists Firefox keys and profiles, even if Firefox isn’t currently installed. It detects preferences and extensions in all profiles, flagging non-standard profiles often created by adware.
Fixable Entries: Except for FF DefaultProfile and FF DownloadDir, most Firefox-related lines can be included in the fix script for deletion.
Add-on Signature Verification: FRST verifies digital signatures of Firefox add-ons and labels unsigned add-ons, which can be a security risk. Example: FF Extension: (Adblocker for Youtube™) - ... [not signed].

Chrome and Other Chromium-based Browsers (Brave, Opera, Vivaldi, Yandex Browser):

Profile Detection: Similar to Firefox, FRST lists Chrome keys and profiles, even if Chrome isn’t installed. It detects preferences and extensions across all profiles, flagging non-standard profiles.
Preferences Scan: FRST’s Chrome scan includes detection of modified HomePage, StartupUrls, enabled Session Restore, custom default search providers, and allowed notifications. Examples:
```
CHR HomePage: Default -> hxxp://www.web-pl.com/
CHR StartupUrls: Default -> "hxxp://www.web-pl.com/"
CHR DefaultSearchURL: Default -> hxxp://www.web-pl.com/search?q={searchTerms}
CHR Session Restore: Default -> is enabled.
CHR Notifications: Default -> hxxps://www.speedtestace.co
```
Including HomePage, StartupUrls, and Notifications entries in the fix script will delete them. Processing other entries can trigger a partial Chrome reset, potentially displaying a “Chrome detected that some of your settings were corrupted…” message in Chrome settings.

New Tab Redirections: FRST detects New Tab page redirections caused by extensions. Example:

CHR NewTab: Default -> Active:"chrome-extension://algadicmefalojnlclaalabdcjnnmclc/stubby.html"
CHR Extension: (RadioRage) - C:\Users\User\AppData\Local\Google\Chrome\User Data\Default\Extensions\algadicmefalojnlclaalabdcjnnmclc [2017-04-07]

To remove these redirects, identify the associated extension and uninstall it using Chrome’s extension management tools (chrome://extensions).

Extension Removal Limitation: FRST fix scripts cannot directly remove Chrome extensions. Use Chrome’s built-in extension management (chrome://extensions) to remove extensions. The exception is extension installers located in the registry (CHR HKLM and HKU entries), which can be deleted by including them in the fix script.
Chromium Browser Support: The same rules for Chrome apply to other Chromium-based browsers like Brave, Opera, Vivaldi, and Yandex Browser. For unsupported browsers, a complete uninstall, reboot, and reinstall is recommended.

Services and Drivers Sections: Analyzing System Components

The “Services” and “Drivers” sections provide detailed information about system services and drivers, crucial for identifying and removing malicious components.

Format:

Services and drivers are listed in the following format:

RunningState StartType ServiceName; ImagePath or ServiceDll [Size CreationDate] (SignerName -> CompanyName) [signature verification]

RunningState: R (Running), S (Stopped), U (Undetermined).
StartType: 0 (Boot), 1 (System), 2 (Auto), 3 (Demand), 4 (Disabled), 5 (FRST assigned – start type could not be read).
[X] Notation: [X] at the end indicates FRST couldn’t find the associated files and is listing the ImagePath or ServiceDll as it is in the registry.

Default Microsoft Services and Unsigned Files: Default Microsoft services pointing to unsigned files often require repair. Example:

==================== Services (Whitelisted) =================

R2 DcomLaunch; C:\Windows\system32\rpcss.dll [512512 2010-11-20] (Microsoft Corporation) [File not signed]
R2 RpcSs; C:\Windows\system32\rpcss.dll [512512 2010-11-20] (Microsoft Corporation) [File not signed]

In such cases, the file needs to be replaced with a known good copy using the Replace: command (refer to FRST directives documentation).

Fixing Services and Drivers:

Removing Bad Services/Drivers: To remove a malicious service or driver, copy the entire line from the FRST log to the fix script. Any associated files also need to be listed separately for removal. Example:
```
R1 94BE3917F6DF; C:\Windows\94BE3917F6DF.sys [619880 2019-03-07] (韵羽健康管理咨询（上海）有限公司 -> VxDriver) C:\Windows\94BE3917F6DF.sys
```
FRST attempts to close the service before removing it. If a running service is deleted, FRST prompts for a system restart to complete the removal.
Service Repair (Themes Service): There’s an exception for the Themes service. If hijacked, you might see:
```
S2 Themes; C:\Windows\system32\themeservice.dll [44544 2009-07-14] (Microsoft Windows -> Microsoft Corporation) [DependOnService: iThemes5]
```
Including this entry in the fix script will repair the Themes service, restoring it to its default state, rather than deleting it.
Unlocked Services: The message "ServiceName" => service was unlocked indicates FRST automatically fixed broken permissions. A new FRST log should be taken to verify the result. If necessary, the standard service line can be included in the fix script for removal.

NetSvcs Section: Network Services

The “NetSvcs” section lists network services.

NETSVCx32: HpSvc -> C:Program Files (x86)LuDaShilpiHpSvc.dll ()
NETSVCx32: WpSvc -> no filepath

Registry Value Removal: Listing a NetSvc entry in the fix script only removes the associated registry value. It does not remove the service itself (listed in the “Services” section).

Complete Removal Example: To remove a NetSvc value, the associated service, and the DLL file, you need to include all three in the fix script:

S2 HpSvc; C:\Program Files (x86)\LuDaShi\lpi\HpSvc.dll [239016 2016-07-21] (Qihoo 360 Software (Beijing) Company Limited -> )
NETSVCx32: HpSvc -> C:\Program Files (x86)\LuDaShi\lpi\HpSvc.dll ()
C:\Program Files (x86)\LuDaShi

One Month (Created/Modified) Section: File and Folder Date Analysis

The “One month (Created/Modified)” section lists files and folders created or modified within the last month in predefined locations.

Date Information: It reports both the creation and last modified dates/times, and file sizes. Folders show 00000000 size.
Scan Limitations: To limit scan time and log size, this scan is restricted to specific locations and primarily lists custom folders, not their contents. Use the Folder: directive for detailed folder content scans.
Digital Signature Check: Digital signature verification is limited to whitelisted Microsoft executables. Use the SigCheckExt optional scan for a broader list of unsigned executables.
File Attributes: FRST adds notations for file attributes: C (Compressed), D (Directory), H (Hidden), L (Symbolic Link), N (Normal), O (Offline), R (Readonly), S (System), T (Temporary), X (No scrub – Windows 8+).

Fixing Files and Folders in “One Month” Section:

Removal: To remove a file or folder listed in this section, copy and paste the entire line into the fix script.
Symbolic Links: FRST correctly handles symbolic links (L attribute). Removing a symbolic link using the fix script will delete only the link, leaving the target file/folder untouched. Alternatively, DeleteJunctionsInDirectory: directive can be used.
Wildcards: Wildcards (*) can be used for file paths in the fix script to target multiple files with similar names. Example: C:WindowsTasksAt*.job. Question marks (?) are ignored for safety. Wildcards are not supported for folders.

FLock and FCheck Sections: Advanced File System Checks

FLock (Locked Files): The “FLock” section lists files and folders in standard directories that are currently locked.
FCheck (File Integrity Check): The “FCheck” section is designed to list potentially problematic files, such as those involved in DLL hijacking, or zero-byte .exe and .dll files in standard directories. This section only appears if such items are detected.
Fixing FLock and FCheck Items: Including entries from these sections in the fix script will move the identified files or folders.

KnownDLLs Section: Recovery Environment (RE) Specific

RE Mode Only: The “KnownDLLs” section appears only when FRST is run in Recovery Environment (RE) mode.
Boot Issues: Missing, patched, or corrupted items in this section can cause boot problems.
Expert Assistance Recommended: Dealing with “KnownDLLs” entries requires caution and expert knowledge. Incorrect fixes can lead to unbootable systems. Seek expert help before taking action. In many cases, a good replacement file exists on the system and can be found using FRST’s search function and the Replace: directive.

SigCheck Section: System File Signature Verification

System File Integrity: FRST verifies the digital signatures of critical system files. Files with incorrect or missing signatures are reported. This section is typically whitelisted (hidden) outside of Recovery Environment if no issues are found.
Malware Detection: Modified system files can indicate malware infection. Remediation requires extreme caution, and expert help is advised, as removing system files can render the system unbootable. Example of a Hijacker.DNS.Hosts infection:
```
C:\WINDOWS\system32\dnsapi.dll [2015-07-10 13:00] - [2015-07-10 13:00] - 0680256 _____ (Microsoft Corporation) 5BB42439197E4B3585EF0C4CC7411E4E
C:\WINDOWS\SysWOW64\dnsapi.dll [2015-07-10 13:00] - [2015-07-10 13:00] - 0534064 _____ (Microsoft Corporation) 4F1AB9478DA2E252F36970BD4E2C643E
```
In such cases, the corrupted file needs to be replaced with a clean copy using the Replace: command.
BCD Recovery Fix: Some malware (like SmartService) disables Recovery Mode. FRST automatically reverts BCD modifications during a scan, indicated by: BCD (recoveryenabled=No -> recoveryenabled=Yes).
Safe Boot Loop: If Safe Mode is corrupted and the system is configured to boot into Safe Mode, it can get stuck in a loop. FRST detects this: safeboot: Minimal ==> The system is configured to boot to Safe Mode. Including this line in the fix script will set the boot mode back to normal, resolving the loop (Vista and later Windows versions).

Association Section: File Association (RE Mode)

RE Mode Only: The “Association” section appears in FRST.txt only when run from Recovery Environment. Outside RE, it’s in Addition.txt. In RE, it’s limited to .exe file association.
.exe Association Issues: Lists machine-wide .exe file associations. Example: HKLM\...\exefile\open\command: C:\Windows\svchost.com "%1" %*.
Restoring Associations: Copying problematic entries to the fix script will restore the default file associations.

Restore Points Section: System Restore Management (RE Mode)

RE Mode Behavior: “Restore Points” appears in FRST.txt in Recovery Environment and in Addition.txt outside RE.
Listing Restore Points: Lists available system restore points.

Windows XP Restore: Only in Windows XP can hives be directly restored using FRST from restore points. On Vista and later, restore points should be managed from Windows System Recovery Options in RE. Example from XP:

RP: -> 2010-10-26 19:51 - 024576 _restore{3216E3D3-FBC5-40AC-B583-63C1B9EE2B6F}\RP83
RP: -> 2010-10-24 13:57 - 024576 _restore{3216E3D3-FBC5-40AC-B583-63C1B9EE2B6F}\RP82
RP: -> 2010-10-21 20:02 - 024576 _restore{3216E3D3-FBC5-40AC-B583-63C1B9EE2B6F}\RP81

Restoring from Restore Points (XP): To restore hives from a specific restore point (e.g., RP82), copy the corresponding line to the fix script: RP: -> 2010-10-24 13:57 - 024576 _restore{3216E3D3-FBC5-40AC-B583-63C1B9EE2B6F}RP82.

Memory info Section: System Memory Details (RE Mode)

RE Mode Behavior: “Memory info” in FRST.txt in RE, more detailed in Addition.txt outside RE (BIOS, Motherboard, Processor info included in Addition.txt).
RAM Information: Provides details on installed RAM, available physical memory, and free memory percentage. Helps diagnose memory-related issues. Discrepancies between reported RAM and expected RAM can indicate faulty RAM, motherboard slot issues, or BIOS limitations (BIOS upgrade needed). 32-bit systems will only report a maximum of 4GB RAM even if more is installed due to 32-bit application limitations.
Virtual Memory: Lists virtual memory and available virtual memory.

Drives and MBR & Partition Table Sections: Disk Information (RE Mode)

RE Mode Behavior: “Drives” and “MBR & Partition Table” in FRST.txt in RE, in Addition.txt outside RE.

Drive Enumeration: Lists fixed and removable drives, including unmounted volumes identified by GUID paths. Example:

Drive c: (OS) (Fixed) (Total:223.02 GB) (Free:173.59 GB) (Model: Force MP500) NTFS
Drive f: (Flash drive) (Removable) (Total:1.91 GB) (Free:1.88 GB) FAT32
Drive g: (Recovery) (Fixed) (Total:0.44 GB) (Free:0.08 GB) (Model: Force MP500) NTFS
Drive x: (Boot) (Fixed) (Total:0.5 GB) (Free:0.49 GB) NTFS
\\?\Volume{74a80af8-ff89-444b-a7a3-09db3d90fd32}\ () (Fixed) (Total:0.09 GB) (Free:0.07 GB) FAT32

Partitioning Scheme: Detects UEFI/GPT or BIOS/MBR partitioning.

UEFI/GPT: Basic GPT layout detection. Example:

Disk: 0 (Protective MBR) (Size: 223.6 GB) (Disk ID: 00000000)
Partition: GPT.

BIOS/MBR: MBR code and partition entries detected. Logical partitions in extended partitions are not listed. Example:

Disk: 0 (MBR Code: Windows 7/8/10) (Size: 465.8 GB) (Disk ID: 73FD73FD)
Partition 1: (Active) - (Size=39.1 GB) - (Type=07 NTFS)
Partition 2: (Not Active) - (Size=426.7 GB) - (Type=0F Extended)

MBR Check: If MBR issues are suspected, an MBR dump can be obtained by running the fix script with: SaveMbr: drive=0 (or appropriate drive number). MBRDUMP.txt will be saved in the FRST download location. It’s recommended to perform MBR dumps in RE mode, as some MBR infections can forge the MBR when Windows is loaded.

LastRegBack Section: Registry Backup Restoration

Registry Backup Information: FRST lists the last system registry backup created by Windows. This backup contains all registry hives and is distinct from the Last Known Good Configuration (LKGC) which only backs up the ControlSet.
System Hive Issues: The header alert "ATTENTION: Could not load system hive" often indicates a need for LastRegBack restoration.
Restoring from LastRegBack: To restore the registry from the last backup, include the LastRegBack: line with the date and time from the FRST log in the fix script. Example: LastRegBack: 2013-07-02 15:09.
