AdwCleaner is a lightweight cleanup utility that scans a Windows PC for adware, browser hijackers, toolbars, and unwanted preinstalled software, then quarantines what it finds so the change can be reversed.
AdwCleaner is a specialist cleaner rather than a full antivirus. It looks for the software that arrives quietly alongside something else: adware that injects banners, browser hijackers that reset a homepage, toolbars nobody remembers installing, and preinstalled programs that a manufacturer added before the machine shipped. The workflow is short. You open the app, click Scan Now, and review a list of detections; anything you accept is quarantined and disabled, then AdwCleaner asks for a restart to finish the cleanup. Detections can be restored or deleted afterwards, and a log records exactly what was found and removed. Because the tool aims at stubborn junkware, it is often the second opinion a technician reaches for when a machine still feels wrong after a regular scan.
The infections it targets rarely announce themselves as malware. They ride along with installers for things people genuinely wanted, which is why an unfamiliar toolbar can appear after somebody downloads a plugin to join a call: invites from services such as Cisco Webex Meetings are a common moment when a browser picks up an extra extension. AdwCleaner is also deliberately narrow. It removes adware, potentially unwanted programs, browser hijackers, and bundled preinstalled software, but it does not try to be real-time protection, so it complements an antivirus rather than replacing one. Technicians tend to keep it nearby for exactly that reason: it finishes a cleanup that a general scanner may leave half done.
The main benefit of AdwCleaner is judgement: it shows you what it found before anything is destroyed. Each detection is quarantined and made inactive rather than erased outright, so a mislabelled file can be restored from the same list, one item at a time or all at once. That reversibility matters because adware lives close to legitimate software, and the tool is honest about the grey areas. Preinstalled programs get their own tab, which is useful when a shop-bought machine ships with trial software nobody asked for. AdwCleaner also speaks the language of whoever has to fix the problem. Logs are plain text, exclusions can be set for files, folders, registry keys, services, processes, URLs, and whole detection families, and a command line lets a technician scan or clean without touching the interface. Reporting a false positive takes one right-click, which is how the scanner keeps improving.
Key capabilities and highlights.
One click runs a scan for adware, potentially unwanted programs, browser hijackers, and unwanted toolbars, then lists each detection with a checkbox so you decide what gets quarantined and disabled. Saving open work is prompted before the cleanup starts.
Programs that arrived with the machine get their own category, listed separately from ordinary detections, so bundled trials and promotional apps can be quarantined without lumping them in with genuine adware. Both lists are handled in the same session.
Detected items are removed from where they were stored, moved into quarantine, and modified to be inactive, which stops them running while keeping the option to reverse the change later. Nothing is erased permanently until you choose to delete it.
The quarantine view lists every held item with a checkbox, so individual entries can be restored to the device or removed for good, and a header checkbox applies the same action to everything at once. Untouched items simply stay in quarantine.
Exclusions can be set for files, folders, registry keys, registry values, services, URLs, processes, or an entire detection family, which keeps a known-good tool out of future scans on a shared machine. The list can be edited or trimmed at any time.
Every scan and cleanup writes a log that opens as plain text in Notepad, and the Log Files tab keeps them in one place, which is exactly what a support forum or a helpdesk ticket tends to ask for.
The same scan and clean functions are available from the command line, including options to skip the restart or to include preinstalled applications, which suits technicians repairing machines remotely or in bulk. AdwCleaner accepts a working directory too, so logs and quarantine can be redirected.
A detection that turns out to be legitimate can be reported as a false positive straight from the results list, which sends the sample to the specialists who maintain the scanner so the next scan is more accurate. One right-click opens the report option.

Common questions about AdwCleaner.
It targets adware, potentially unwanted programs, browser hijackers, unwanted toolbars, and preinstalled software that came with the machine. It is not a general antivirus, so it does not aim to remove viruses, ransomware, or rootkits.
AdwCleaner runs as a standalone utility without a conventional installation, though it does write a small set of files to the system, including its quarantine and log folders, and those are cleaned up if you uninstall it.
Cleaning in AdwCleaner normally ends with a prompt to restart so that quarantined items are fully disabled. There is a command-line option that skips the reboot, but the standard flow expects one.
Yes. AdwCleaner holds quarantined items rather than destroying them, and the Quarantine tab lets you restore any of them individually, or select everything and restore in a single action.
Add it under Settings, then Exclusions. You can exclude a file, folder, registry key or value, service, URL, process, or a whole detection family, and edit or remove those entries later.
No. It is a cleanup tool for adware and junkware that runs on demand, so it works alongside an antivirus rather than providing the ongoing, real-time protection that security suites offer.
Yes. Command-line options cover scanning, cleaning, and uninstalling, with switches to skip the restart, include preinstalled applications, or change the working directory used for logs and quarantine.
Skip Basic Repair during a normal cleanup. Running it is only recommended when a support agent asks you to, because it is a separate repair step rather than part of the standard adware removal process.
