AdwCleaner is a powerful program that is specifically designed to search for and remove adware, toolbars, potentially unwanted programs (PUPs), and browser hijackers from your computer.

By using AdwCleaner, you can easily eliminate these types of programs, improving your overall user experience and browsing safety. It effectively frees your computer from unwanted programs and malware, helping to restore optimal performance.

Is your PC acting strangely? It could be plagued with adware, PUPs, or a browser hijacker. Malwarebytes AdwCleaner is here to help. It scans and removes annoying programs that slow down your computer and hinder its performance.

AdwCleaner targets programs that are often bundled with free software downloads from the internet. Many times, when you download and install a program, the installation process may mention that additional programs will be installed alongside the main program. Unless you perform a Custom install and carefully review the options, these unwanted programs will be automatically installed on your computer, resulting in extra browser toolbars, adware, and other unwanted software. AdwCleaner is specifically designed to detect and remove these types of programs, effectively freeing your computer from unwanted programs and malware.

Adware, as the name suggests, is software that displays unwanted ads. It can be in the form of free software supported by advertisements that appear in pop-up windows or toolbars on your computer or web browser. While most adware is annoying but harmless, some types may collect your personal information, track your browsing habits, or even record your keystrokes.

Adware is commonly bundled with free software, but it can also be installed on your browser or operating system through security vulnerabilities. You may suspect that your device is infected with adware if you start seeing unexpected ads in applications where they hadn't appeared before, or if pop-ups appear on your computer's desktop even when you're not browsing the internet. Another sign may be if your browser's homepage has been changed without your consent. You can use an adware scanner, such as the one included in AdwCleaner, to check if your device is infected.

To prevent adware, it's important to use an antivirus program with an adware cleaner feature. Additionally, make sure to keep your browser, operating system, and software up to date with the latest updates and security patches. Enabling a firewall when using the internet can also provide an extra layer of protection. Download AdwCleaner now to effectively remove adware and other unwanted programs from your Windows PC and enjoy a cleaner, safer browsing experience.

Is AdwCleaner included in Malwarebytes?

Yes, but AdwCleaner is included as a separate tool within the Malwarebytes software suite. Malwarebytes acquired AdwCleaner in 2016 to enhance its capabilities in detecting and removing potentially unwanted programs (PUPs) and adware. AdwCleaner specializes in scanning and eliminating adware, browser hijackers, and other unwanted software that can affect your computer's performance and browsing experience. While both tools are part of the Malwarebytes family, they serve slightly different purposes and can be used together for a comprehensive malware and PUP removal solution.

Although both ADWCleaner and Malwarebytes target Potentially Unwanted Programs (PUPs) and some Potentially Unwanted Modifications (PUMs), they have distinct detection capabilities. While there are plans to integrate all of ADWCleaner's detections and signatures into Malwarebytes in the future, this integration has not yet occurred. Consequently, ADWCleaner can still identify certain items that Malwarebytes does not, although the disparity is not as significant as before.

Malwarebytes has become more proactive in classifying and detecting items as PUPs, but if you frequently download unknown software or installers that may contain PUPs, it is still advisable to occasionally scan with ADWCleaner to ensure you haven't inadvertently installed any PUPs that Malwarebytes might have missed.


Adware and PUP detection and removal
AdwCleaner is specifically designed to target and remove adware, PUPs, and other unwanted programs that may be causing intrusive ads, redirecting web pages, or compromising your browsing experience.

Browser reset
It has a built-in feature that allows you to reset your web browsers to their default settings, which can help remove unwanted extensions, home page hijackers, and other browser-related issues.

Scan and clean system folders
It scans system folders, such as Program Files and ProgramData, for potentially unwanted files and folders that may have been installed by adware or other PUPs.

Quarantine and restore
It has a quarantine feature that allows you to isolate suspicious files and restore them later if needed, giving you more control over the cleaning process.

Regular update
AdwCleaner is regularly updated with the latest adware and PUP definitions, ensuring that it can effectively detect and remove the latest threats.

Simple and easy-to-use interface
It has a simple and intuitive interface that makes it easy for users, even those with limited technical expertise, to scan and clean their systems.

Languages supported
Arabic, Bulgarian, Czech, Danish, German, Greek, English, Spanish, Basque, French, Hungarian, Indonesian, Italian, Japanese, Korean, Dutch, Polish, Portuguese, Romanian, Russian, Slovak, Thai, Turkish, Ukrainian, Vietnamese, and Chinese.


Is AdwCleaner safe to use?
Yes, AdwCleaner is generally considered safe to use. It is developed by Adlice Software, a reputable company known for creating effective security tools. However, as with any software, it is always recommended to download AdwCleaner from the official website or a trusted source like FileHorse to ensure you are getting the legitimate version.

Does AdwCleaner remove viruses and malware?
The app is primarily designed to target and remove adware, potentially unwanted programs (PUPs), and browser-related issues. It may not be as effective against other types of malware such as viruses, trojans, and worms. For comprehensive protection against all types of malware, it is recommended to use AdwCleaner in conjunction with a reliable antivirus or antimalware solution.

Can AdwCleaner undo changes made during the cleaning process?
Yes, AdwCleaner has a quarantine feature that allows you to isolate suspicious files and restore them later if needed. This can be helpful in case any false positives are detected or if you want to undo changes made during the cleaning process. However, it is important to carefully review the scan results and ensure that you are restoring legitimate files to avoid any potential re-infection.

Does AdwCleaner provide real-time protection?
No, it does not provide real-time protection. It is a reactive tool, meaning it scans and removes adware and PUPs after they have already been installed on your system. It does not actively prevent future infections or provide ongoing monitoring of your system. For real-time protection against malware, you will need to use a dedicated antivirus or antimalware program.

Can I use AdwCleaner alongside my antivirus software?
Yes, it can be used alongside your antivirus software. It is designed to complement antivirus programs by focusing on adware, PUPs, and browser-related issues, which may not be detected by traditional antivirus software. However, it is recommended to use only one antivirus or antimalware program with real-time protection enabled at a time to avoid conflicts and performance issues. You can use AdwCleaner periodically as a supplementary tool for scanning and cleaning your system from adware and PUPs.
