What the Captcha Reverse scammers want

From our report of Apr 2021 · not reviewed since

CaptchaReverse – a deceitful portal that will bombard your device with ads if you accept its notifications

Captchareverse.com is the address of an untrustworthy website to which Windows, Mac, and Android users can be redirected if they have an adware infection.

If you end up on this page, please don't accept its notifications. Otherwise, ads will start popping up directly on your screen or desktop.

Ads from this push notification virus are deceptive as they usually have nothing in common with the portals you will be redirected to if you press them. Furthermore, you could end up on any of its affiliated portals without clicking on anything if a sudden redirect is triggered.

This article contains a brief summary of Captcha Reverse virus and instructions to remove its notifications from your browsers (Chrome, Safari, etc.). Moreover, we've added free tutorials on how to eliminate the adware that caused the initial redirect and system recovery options if your device's performance is reduced or it's exhibiting any abnormal behavior.

Developers of potentially unwanted programs (browser hijackers, adware, etc.) often promote one another. That's why you could be redirected to treacherous pages with dangerous content like N19.biz virus, Acceptww.com virus, Nbryb.com virus, and so on. These websites exploit the legitimate service of push notifications to deliver ads and cause redirects.

Captcha Reverse infection does the same. It doesn't deliver any sports updates, breaking news, or anything worthwhile. It shows deceptive ads that, when clicked, redirect to affiliated pages. Some of them might be harmless, but others might have dangerous contents, such as:

What's worse, you could be exposed to any of these dangerous affiliated websites on-demand if a sudden redirect is triggered. That's because PUP developers care only about getting paid, not their user safety or privacy. Thus push notifications should be enabled only on pages that you frequently visit and trust.

Although PUPs are deemed less dangerous than malware, they should not be installed on any device. Browser hijackers, adware, and similar junkware could still endanger both you and your device by acting as a bridge to severe infections, like ransomware, Trojans, etc.

That's why you have to remove it ASAP. According to IT experts, the best way to do this is to perform a full system scan with reliable anti-malware software. Free security tools such as or will automatically eliminate any cyber threat that found its way to your device.

After the removal is done, use our removal guides below to delete Captcha Reverse notifications from your browsers.

What to do if you ran the Captcha Reverse command

Whether you ran the command decides everything else, so the first step checks that.

  1. Step 1: Check whether the pasted command ran

    The fake check asked you to press Windows + R, paste and press Enter. Open the same box and look at its drop-down history: a powershell, mshta or curl line you did not type yourself is the command Captcha Reverse gave.

    Once run, it fetches malware within seconds, so take the PC offline and follow all the remaining steps. If the history is empty or harmless, nothing was started on the Windows 11 or Windows 10 PC.

    Full procedure with screenshots: Run a Microsoft Defender Offline scan

  2. Step 2: Scan the PC, then run the offline scan

    A scan finds the parts of Captcha Reverse 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.

  3. Step 3: Change passwords from another device and sign out other sessions

    Captcha Reverse can copy saved passwords, cookies and session tokens and send them out in seconds, so cleaning the PC does not undo the theft.

    Change your passwords on a device that was never infected, starting with the e-mail account, since every other reset goes through it. On each account, end all other sessions and check the recovery e-mail, phone number and forwarding rules.

    Then turn on two-step verification. Sign in on the Windows 11 or Windows 10 PC again only after the offline scan is clean.

  4. Step 4: Delete scheduled tasks that bring it back

    Programs like Captcha Reverse add a scheduled task so they return after an uninstall or reopen a page at every sign-in. Start Task Scheduler, open Task Scheduler Library and sort by Last Run Time to see what ran recently.

    On the Actions tab, a program in a user folder, a script or a web address is a warning sign; right-click such a task and choose Delete.

    Tasks with names copying Google, Edge or Windows updaters but pointing to an odd folder are typical. The tool looks the same in Windows 11 and Windows 10.

Protect your privacy - employ a VPN

However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise.

In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. is one of the leading file recovery solutions you can find on the market - it is likely to restore even lost emails or data located on an external device.

Uninstall Flash Player and don't update it to avoid PUP infections

Browser hijackers, unwanted toolbars, adware, and other PUPs can be delivered in many different ways, from software bundles to deceptive ads.

Our team has determined that one of the most popular PUP spreading techniques is via fake browser and codec updates that can be seen on various shady or hacked websites.

Adobe discontinued this software on December 31, 2020. The company issued a statement to uninstall Flash Player from devices for security reasons after discontinuing it on December 31, 2020. But since many people still don't know that, cybercriminals are exploiting it.

They develop ads, prompts, sometimes even the whole website to help them distribute their vile creations. Fake browser updates could contain pesky PUPs and hazardous malware, such as ransomware, keyloggers, etc. So if you ever see a prompt urging to update or install browser plugins or software, verify the source before proceeding as the suggested download may be malicious.

Comprehensive guide to remove Captcha Reverse from your browser and adware from your device

Cybercriminals are exploiting the legitimate push notification service by tricking people into pressing the Allow button and displaying them ads directly on the desktop or screen afterward.

Thus internet users have to stay aware of sites like Captchareverse.com and not accept their notifications.

First, you have to perform a full system scan with a proper anti-malware tool to begin the removal process. Such software is essential for protection today, as cyberattacks continue to pose significant risks. Reliable security software will block dangerous websites and prevent your device from getting infected with severe malware.

After you remove adware, PUPs, and any other suspicious apps or files, you can use our free guides below to erase notifications from Captcha Reverse. Once all infections are gone, run system diagnostics with compatible software to restore your device to a pre-contamination phase and ensure it runs without any hitches.

Questions about Captcha Reverse

What is CaptchaReverse?

CaptchaReverse is a deceptive website (captchareverse.com) that tricks users into accepting push notifications. It redirects Windows, Mac, and Android users to a page where clicking "Allow" enables desktop notifications. Once granted, CaptchaReverse bombards devices with deceptive ads that appear directly on screens and desktops instead of in browsers.

The notifications contain misleading content with no relationship to the websites users actually visit. Clicking ads redirects to affiliated sites, earning money for CaptchaReverse developers. The site exploits legitimate push notification technology for malicious advertising purposes.

Should I click Allow when CaptchaReverse asks for notification permissions?

No, absolutely do not click "Allow" for CaptchaReverse notifications. Accepting permissions enables constant ad bombardment on your desktop. These notifications are deceptive, misleading, and designed solely to earn money for criminals.

Clicking the ads redirects to affiliated sites containing potentially dangerous content including malware distribution. CaptchaReverse makes money from each click and redirect, rewarding your attention with intrusion.

Instead, close the page entirely or navigate away. Legitimate websites rarely request notification permissions for valuable content. If you accidentally clicked "Allow," immediately revoke notifications through browser settings.

Why am I seeing CaptchaReverse pop-ups and ads?

CaptchaReverse pop-ups indicate you've encountered adware or a browser hijacker on your system. These PUPs redirect your browsing to CaptchaReverse and other malicious sites. Some ads appear as notifications on desktop (outside browser windows) if you mistakenly enabled CaptchaReverse notifications.

Visiting untrustworthy websites increases encounter frequency. Software bundles often include adware causing redirects. The appearance of CaptchaReverse or similar sites may indicate installed programs actively promoting malicious content.

Running antimalware scans reveals adware responsible for redirects. The sites appear as targeted attacks exploiting your system's vulnerabilities. Address the underlying adware to stop pop-ups permanently.

What happens if I click the ads shown in CaptchaReverse notifications?

Clicking CaptchaReverse ads redirects to affiliated websites, many containing dangerous content. These redirects may lead to:

  • malware distribution sites
  • phishing pages stealing credentials
  • scareware promoting fake security software
  • adult content
  • shopping sites infected with click-fraud malware

You could be exposed to ransomware, trojans, keyloggers, or other infections. The ads appear legitimate through deceptive headlines designed to trigger curiosity or concern. Even if no malware immediately appears, your click generates income for criminals encouraging further attacks.

Your personal information may be compromised through phishing sites. Avoid clicking notifications entirely. If you accidentally clicked, immediately run security scans and monitor accounts for unauthorized activity.

How do I remove CaptchaReverse notifications from my browser?

First, revoke notification permissions in browser settings. In Chrome: Settings > Privacy and security > Site settings > Notifications > search captchareverse.com and click Remove. In Firefox: Preferences > Privacy > Permissions > scroll to Notifications and find captchareverse.com to remove.

In Safari: Preferences > Websites > Notifications > select captchareverse.com and choose Deny. These steps immediately stop notifications. Clear browser cache, cookies, and browsing history to remove tracking data.

Scan with antimalware software to detect underlying adware causing redirects. Reinstall browser if notification removal proves difficult. Change passwords for important accounts if you fear credential compromise from phishing.

Is CaptchaReverse malware or just an annoying website?

CaptchaReverse operates as adware and browser hijacker rather than traditional malware. It's classified as PUP (potentially unwanted program) that doesn't directly damage files or destroy systems like malware. However, it acts as a gateway to malware infection through redirected ads and malicious sites.

PUPs still pose security and privacy risks through tracking, social engineering, and exposure to dangerous content. While technically less dangerous than viruses or ransomware, CaptchaReverse enables infection with actual malware through its network of malicious affiliated sites.

The distinction matters less than the response—both require immediate removal and security scanning. Users affected by CaptchaReverse should run comprehensive antimalware scans despite its PUP classification.

How did CaptchaReverse end up on my system?

CaptchaReverse infection typically occurs through software bundles with freeware and shareware. When installing free programs, adware installs automatically if users choose Recommended installation settings. Deceptive websites directly redirect to CaptchaReverse pages attempting to get notification permission.

Malicious advertisements on compromised sites trigger auto-redirects. Browser extensions or plugins installed from untrusted sources include redirection scripts. Flash Player fake updates often bundle adware causing redirects.

Drive-by downloads from compromised sites automatically install adware in background. To prevent future infections, always select Advanced/Custom installation settings, deselect suspicious options, avoid suspicious websites, keep software updated, use reliable antimalware with real-time protection, and verify browser extensions' legitimacy before installation.

How do I remove the adware causing CaptchaReverse redirects?

Run comprehensive antimalware scans with reputable security software. Download scanning tools on clean devices and transfer via USB if system is heavily compromised.

Excellent free options include Microsoft Defender (built into Windows) and security-focused tools. Full system scans detect adware responsible for CaptchaReverse redirects and automatically quarantine infected files.

Run multiple scans to ensure complete removal. Check Add/Remove Programs for suspicious applications and manually uninstall them. Scan browser extensions for malicious add-ons causing redirects.

Reset all browser settings to defaults to remove hijacked search engines and homepages. After automated removal, run system diagnostics tools to repair damage caused by adware. Monitor system performance—removal should restore speed and stability.

Will Fortect remove Captcha Reverse?

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 Captcha Reverse, 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.
