Start with the unwanted behavior you notice
A browser homepage that changes unexpectedly, unfamiliar toolbars or software installed alongside another program can justify a closer inspection. AdwCleaner focuses on adware, potentially unwanted programs and browser hijackers. It is useful when the problem concerns intrusive additions rather than an ordinary application you simply no longer need. A detection still deserves review: potentially unwanted does not necessarily mean the same thing as a destructive virus.
Write down the symptom before running a scan. Does it appear in one browser, only after signing in, or immediately after Windows starts? This helps you evaluate whether the cleanup addressed the original problem. Not every popup comes from installed adware; browser notification permissions and website behavior can also explain unwanted messages. A clean result therefore should not end an investigation if the same symptom continues.
Scan first and review the selected items
Download the current executable from the Malwarebytes AdwCleaner page, open it and read the license and prompts. Save work before any cleaning stage because applications may close and Windows may need to restart. Begin with a scan, then inspect the detected names and locations. Distinguish a program you intentionally use from a bundled extra that you do not recognize or need.
AdwCleaner also handles selected preinstalled software, so review that part of the results separately. Do not assume that every application supplied with a computer is malicious or dispensable. Quarantine the items you have chosen and follow the restart prompt when required. Afterwards, read the log and check the original browser or application again. Keep a record of the change if you may need to explain it later.
Quarantine provides a review stage
The quarantine view lets you inspect isolated items and offers restoration or deletion choices. If an expected application stops working after cleanup, investigate the relevant detection before making another broad change. Restore only when you understand what the item is and why it is trusted. Keeping a log is more useful than repeatedly removing the same entry without checking what recreates it.
Avoid running optional repair operations simply because they are available. The publisher’s cleanup instructions specifically reserve Basic Repair for situations directed by support. Changes to network or browser settings should have a reason connected to the problem. Revo Uninstaller suits a different task: deliberately removing a known application through an uninstall workflow. It does not replace an adware scan or decide whether a detected item is trustworthy.
Know the scope of the free Windows tool
AdwCleaner is free and runs as an on-demand cleanup utility. It does not provide continuous protection or replace a broader security product. Malwarebytes offers a wider scanning and protection product separately, with features depending on its edition. Using a focused scanner can help address a particular unwanted-software problem, but no single scan proves that every possible threat is absent from a computer.
For current AdwCleaner releases, follow the publisher’s version-specific compatibility guidance for Windows 10 and 11. Older Windows releases need separate legacy guidance, not an assumption that the newest executable will work. The utility starts from its downloaded executable without a conventional setup wizard. After cleaning, review how the unwanted addition arrived and avoid reinstalling the same bundle, otherwise the original symptom may return despite a successful cleanup.
