CrushClans ads: annoying and unnecessary

CrushClans is a browser extension that you could have came across while browsing the web.

Allegedly, its main purpose is to offer users various games to play online. However, this app is nothing more but adware - its main goal is to expose people to as many advertisements as possible. It is likely to benefit the most when users click on shown pop-ups or other ads since a pay-per-click revenue is commonly used.

As a result of the installation, you might see ads much more frequently. In the background, your online activities might also be tracked and sent off to a remote server. Therefore, if you might believe that this extension can grant you entry to games to play online, keep in mind that there are plenty of unwanted side effects that might endanger your online security and privacy.

Just to be clear - this extension is not a virus but rather a potentially unwanted program that can make web browsing activities frustrating. In fact, it falls into the adware category because its primary aim is to serve third-party advertisements and make click revenue.

If you love to play online games, you might be lured into installing it, however, most users install it unwillingly alongside some free programs downloaded from the Internet. We want to warn you in advance to be very careful with CrushClans ads that this ad-supported program will present to you because they can contain links leading to questionable and potentially hazardous Internet sites.

According to the developer of this adware, the program displays "a limited number of advertisements daily to each of the users in the form of new page tabs, banner ads, video advertisements, and text link advertisements."

It means that you will receive ads in pop-up windows, banners, and also ads injected into certain text spots on websites that you visit. Do not be mistaken, and do not click on these ads as they do not originate from sites that you visit.

First of all, they can be deceptive and point you to strange websites. Second, they can force you to visit potentially dangerous places on the Internet. An innocent click on an interesting-looking ad can lead to sad consequences.

You can remove CrushClans adware with programs like or, if you wish, manually. Our team wants to help inexperienced users to delete malware and spyware manually, so we have prepared detailed removal instructions for you! You can avoid the cleaning of the browser process with the help of - it can do that for you automatically and then fix potentially damaged system components.

How CrushClans ads got on your PC

From our report of May 2021 · not reviewed since

As we have previously mentioned, PUPs hijack computer systems with the help of safe-looking freeware applications .

We believe that other adware programs might be advertising that website via pop-up ads. However, if you have never entered that site but this adware now lurks in your computer system, you should look back and remember the last programs that you have installed.

You should install software using the Custom/Advanced option, not the Default/Standard one, because the latter option contains pre-marked permissions to install "recommended" third-party software . To opt out of the additional pieces of software, decompose the software pack using Custom/Advanced settings.

How to remove CrushClans ads

Uninstall first, then remove what stays behind, so the ads do not come back after a restart.

  1. Step 1: Uninstall CrushClans ads

    CrushClans ads is removed like any other program, from the list of installed apps. In Windows 11 that is Settings > Apps > Installed apps, in Windows 10 Settings > Apps > Apps & features, and in both you can also use Control Panel > Programs and Features.

    Select CrushClans ads, click Uninstall and follow the uninstaller to the end. Then look at the entries just above and below it when the list is sorted by date: bundled programs install at the same minute.

  2. Step 2: Remove it from startup

    Press Ctrl + Shift + Esc to open Task Manager and select Startup apps (Windows 11) or the Startup tab (Windows 10). Disable entries you do not recognise, especially ones with no publisher or with a name that copies a Windows component.

    Right-click an entry and choose Open file location to see where it runs from: programs in %AppData% or %Temp% deserve a closer look. Some entries are not listed there but in the registry Run keys, which the procedure below shows how to check.

  3. Step 3: Delete the folders left behind

    Uninstalling often leaves the program's folders, and some threats reinstall themselves from them.

    Press Windows + R, type %LocalAppData% and press Enter, then do the same for %AppData% and %ProgramData%, and look for folders named after CrushClans ads, its publisher or created on the day the problem started.

    Delete those folders, and check C:\Program Files and C:\Program Files (x86) too.

    If Windows says a file is in use, end it in Task Manager or delete the folder after a restart in Safe Mode. The folders are the same in Windows 11 and Windows 10.

  4. Step 4: Reset the browser

    A reset removes what the steps above could miss:

    • changed start pages
    • site permissions
    • hidden settings

    In Chrome open Settings > Reset settings > Restore settings to their original defaults; in Edge Settings > Reset settings; in Firefox Help > More troubleshooting information > Refresh Firefox.

    Tip: Bookmarks and saved passwords stay, while extensions are turned off and the search engine and start page return to the defaults.

    Reset every browser on the PC, including Edge, which Windows 11 and Windows 10 always have.

    Chrome Settings page with the Reset settings section open
    Chrome on Windows 11: Settings > Reset settings.

  5. Step 5: Scan the PC, then run the offline scan

    A scan finds the parts of CrushClans ads that the manual steps cannot see. In Windows Security > Virus & threat protection > Scan options, start a Full scan and quarantine what it reports.

    Follow it with Microsoft Defender Antivirus (offline scan) > Scan now, which restarts the PC and checks the disk while Windows and the malware are not running.

    It takes about 15 minutes and works the same in Windows 11 and Windows 10. If either scan finds something, run the full scan again after removal until it comes back clean.

    Windows Security Scan options with Microsoft Defender Antivirus offline scan selected
    Windows 11: Windows Security > Virus & threat protection > Scan options.

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices.

Avoid any unwanted government tracking or spying by going totally anonymous on the internet.

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings.

Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact - you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use for the data restoration process.

Remove CrushClans and stop annoying ads

If you are looking for a way to remove unwanted and intrusive ads, you can find a detailed manual removal tutorial down below.

In case you are not ready or if you do not want to spend time studying these instructions and doing all the work by yourself, simply employ anti-malware software and let it complete CrushClans removal for you. It is the easiest and the most efficient way of removing spyware-type programs.

Since you are dealing with a browser extension here, you should pay the most attention when remediating the web browsers - don't forget to clean web data, cookies, and other leftovers; alternatively, you can simply reset the web browser that was affected by adware.

Questions about CrushClans ads

Can I safely uninstall CrushClans ads?

If you did not install CrushClans ads yourself and it is not part of your hardware or a program you rely on, yes. Uninstalling an unwanted program does not harm Windows. Before you do, search the exact name and publisher to be sure it is not a driver tool, a printer utility or a game launcher with an odd name.

Then remove it from Settings, Apps, Installed apps. Ignore any offers or warnings in its uninstaller about losing protection or performance. Afterwards check Startup apps and your browsers for leftovers, and restart once to confirm that it does not reinstall itself.

CrushClans ads will not uninstall. What can I do?

First restart the PC and try again, because the program may have been running and locked its own files. If the uninstaller is missing or fails, start Windows in Safe Mode, where most third-party programs do not start, and remove CrushClans ads from Installed apps there.

If it still refuses, delete its startup entry and its scheduled task, restart, and try once more. A program that actively prevents removal is behaving like malware, so finish with a Microsoft Defender offline scan. Avoid third-party uninstallers offered on search ads; several of them are unwanted programs themselves.

CrushClans ads has no uninstaller. What now?

Some adware does not register itself properly, or its uninstaller only opens a web page. First try Settings > Apps > Installed apps and the older Control Panel > Programs and Features; one may list it when the other does not.

If neither works, disable its entry in Task Manager > Startup apps, restart, and run a Microsoft Defender full scan and offline scan, which remove known adware files. Then, if anything is left, delete the folder it ran from, which you can find by right-clicking the process in Task Manager and choosing Open file location.

An ad showed a phone number and I called it. What now?

The number belongs to scammers, not to Microsoft or an antivirus company. If you only talked, hang up and do not call back. If you let them connect to the PC, disconnect it from the internet, uninstall the remote access program they used, such as AnyDesk, TeamViewer, ScreenConnect or UltraViewer, and run a full and offline scan.

If you paid or gave bank details, call your bank at once on the number printed on your card. Change any passwords you typed while they were connected, and report the call.

Does adware steal passwords?

Ordinary adware is built to show ads, not to steal logins, and most of it never touches saved passwords. The line is blurry, though. Extensions that can read every page could capture what you type, and adware ads sometimes lead to phishing pages that ask for passwords directly.

If you entered credentials on a page reached through an ad, change that password from a clean device and turn on two-step verification. Otherwise, removing ad-supported program and clearing cookies is usually enough.

Can adware slow down my PC?

Yes. Adware runs in the background, loads ad scripts, opens extra tabs and contacts its servers, all of which use processor time, memory and bandwidth. Ad-heavy extensions also slow down every page, because they inspect and change it before you see it.

The effect is strongest on older PCs and when several adware programs arrived together. After removal, restart the PC and check Task Manager for anything still using a lot of resources that you do not recognise. Speed usually returns to normal once the ads stop.

I clicked on one of the ads. Am I infected?

Probably not. Clicking an ad usually only opens a page, and a page cannot install programs on an up-to-date Windows PC without your help.

You are at risk only if you then downloaded and ran a file, allowed notifications, entered card or login details, or called a phone number shown on the page. Delete any download and run a full and offline scan.

Change passwords you typed, from a clean device. Call your bank if you gave card details. If you called a number or allowed remote access, see the next question.

Why didn't my antivirus catch CrushClans ads?

Many security products do not block adware or notification sites by default, because users often agreed to them, even through a misleading prompt. Notification spam installs nothing at all, so there is no file to detect.

In Windows 11 you can make Microsoft Defender block potentially unwanted apps: open Windows Security > App & browser control > Reputation-based protection settings and turn on Potentially unwanted app blocking. If notifications caused the pop-ups, no scanner will report them; the fix is in the browser's site settings.

Will Fortect remove CrushClans ads?

Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.

For CrushClans ads, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.

Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
