Clean Your PC of Unwanted Software with Malwarebytes AdwCleaner
Malwarebytes AdwCleaner efficiently detects and removes adware, toolbars, and other potentially unwanted programs, offering a straightforward solution for maintaining your system's performance.
AdwCleaner: Fast, Free, and Focused Adware Removal
AdwCleaner is a free, lightweight anti-adware utility published by Malwarebytes and widely distributed via ToolsLib. Designed specifically to hunt down adware, potentially unwanted programs (PUPs), browser hijackers, unwanted toolbars, and spyware, it delivers targeted cleanup without the heavyweight footprint of a full antivirus suite.
What’s New and Current State
AdwCleaner is actively maintained with frequent signature and engine updates. Recent builds (including the 8.x series) continue to refine detection and cleaning routines. The ToolsLib distribution shows ongoing updates and checksum information for downloads, which helps verify file integrity before running the tool.
Key Features
- Targeted removal: Specialised detection for adware, PUPs, toolbars, hijackers, and spyware.
- No installation required: Portable executable that runs directly after download, minimizing system impact.
- Fast scans: Quick system and browser scans that often complete in seconds or minutes depending on the system.
- Quarantine and restore: Isolates suspicious items so you can review and restore if needed.
- Detailed logs: Comprehensive post-scan reports for troubleshooting and support purposes.
- Compatibility: Supports Windows 7, 8, 8.1, 10 and 11 (32 & 64-bit).
- Checksum verification: ToolsLib provides MD5/SHA1/SHA256 signatures for downloaded files to confirm authenticity.
Why Use AdwCleaner
AdwCleaner excels when you need a fast, focused cleanup tool. It’s ideal for removing bundled software that degrades browsing experience or tracks activity, and for restoring browser settings altered by hijackers. Because it doesn’t require installation, it’s a convenient emergency tool to run from a USB drive or after a suspected infection.
How to Use AdwCleaner
- Download the latest AdwCleaner package from a trusted source such as ToolsLib or the publisher’s site.
- Verify the file checksum (MD5/SHA1/SHA256) where available to ensure the download is authentic.
- Run the executable and click 2Scan Now to locate adware and PUPs.
- Review detections and select items to quarantine or remove.
- Click Clean and follow prompts; a restart may be required to complete the process.
- Examine the generated log file for details and retain it for support or record-keeping.
Performance and Reliability
AdwCleaner is engineered for speed and low resource usage. It scans quickly, often catching remnants of installers and browser modifications left by unwanted software. Detection accuracy focuses on user-impacting behaviors (ads, redirects, unwanted installs) rather than broad heuristic blocking, making it a practical companion to full antivirus products.
Distribution and Safety Notes
ToolsLib hosts multiple AdwCleaner releases and provides download statistics and checksums to validate files. The publisher is listed as Malwarebytes, and the project has a very large user base and millions of cumulative downloads, reflecting long-standing community trust and active maintenance.
Who Should Install It
- Users seeing persistent ads, browser redirects, or new toolbars after installing other software.
- Technicians and helpers who need a portable, reliable cleanup utility for client machines.

Core Advantages

Does AdwCleaner remove viruses?
AdwCleaner is not designed to remove viruses or other types of malware such as Trojans, worms, or ransomware.

For full protection against malware, you should use a comprehensive antivirus program.
Do I need to install AdwCleaner?
No, AdwCleaner is a portable software that doesn't require installation. You can simply download the executable file and run it on your computer without leaving any traces behind. This makes it convenient to use on multiple devices or when you're on the go.
Does AdwCleaner work on Mac or Linux?
