What is the Reverse Captcha virus?
Push notifications are a mixed blessing. On the one hand, they bridge the gap between websites and their audiences by bringing content updates to users’ fingertips. On the other hand, they are the central element of numerous cybercrime plots whose goal is to disseminate malware, conduct phishing attacks, and promote garbage online marketplaces. The Reverse Captcha pop-up virus is the prime example of such a spammy tactic. The idea is to force hits to reversecaptcha.com site or its clones captchareverse.com, reverscaptcha.com, revercecaptcha.com and highercaptcha-settle.com. All of these pages are disguised as garden-variety human verification pages that try to manipulate the visitor into making a blunder.
Here is how the Reverse Captcha (a.k.a. ReversCaptcha) scam tries to bait unsuspecting users. The landing page pretends to be an intermediate link between a legit-looking ad and some supposedly interesting materials such as a sensational video or breaking news. To prove that the person is not a robot, they are prompted to click the “Allow” button on a pop-up alert that appears right below the URL area. Even at this early stage of the hoax, it’s clear that something isn’t right. The dialog box doesn’t mention anything along the lines of confirming that the user is real. Instead, it says reversecaptcha.com or its spin-off wants to show notifications.

|Removal||Scan your PC with Combo Cleaner for Windows to detect all files related to Reverse Captcha pop-up virus. Free scan determines if your system is infected. To get rid of the threat, you need to purchase the full version of the anti-malware tool.
In plain words, the whole human verification narrative is nothing but a decoy that obfuscates a permission that should never be granted. If the page gets the green light to do what it wants, the victim’s routine will be flooded with web push notifications showing up all over the screen. Contrary to the ethical use of this technology, in this scenario the ads will contain hyperlinks that lead to untrustworthy places on the web. They run the gamut from fishy advertising networks and e-commerce resources to phishing sites and direct malware downloads. On PCs running Windows 10, these pop-ups may emerge in the system tray area, where the recently added “News and Interests” information resides.
One of the most serious implications of the Reverse Captcha issue is that the irksome advertisements may be triggered from malware that’s already inside the device. The infection causes a reorganization of the system preferences at the level of the Registry and web browsers. Google Chrome, Mozilla Firefox, and other popular web surfing tools become riddled with harmful plugins that can replace the default search engine with a knock-off service created solely for harvesting unique hits. Therefore, the starting point in addressing the Reverse Captcha issue is to find the unwanted program and eliminate all files associated with it. This is precisely what the tutorial below will explain in detail.

Use Control Panel to get rid of Reverse Captcha virus
• Open up the Control Panel from your Start menu in Windows. Depending on the OS build, select Uninstall a program (Windows 10, 7 and Vista) or Add or Remove Programs (Windows 8).
• To facilitate the process of locating the threat, sort the programs list by date to get the latest ones displayed at the very top. Find an unfamiliar, suspicious entry under the Name column, click Uninstall and follow further directions to get the removal done.
Reverse Captcha pop-up removal for Android
Here’s a walkthrough to sort out the Reverse Captcha pop-up issue on an Android device, which might also be a target in this malvertising campaign. Keep in mind, though, that uninstall attempts in regular mode may be futile due to the mechanics of this persistent infection. Therefore, you need to perform the procedure in safe mode. Go ahead and do the following:
• Press and hold the Power button. Then, tap and hold the Power off option on the screen. Doing so will boot your device into safe mode.
• Android will ask you to confirm that you’d like to enter safe mode. Tap OK on the dialog.
• You will now see the Safe mode inscription at the bottom left of your screen. Go to Settings and choose Apps.
• Scroll down the list of applications, focusing on the ones that were installed recently. Find Reverse Captcha or another sketchy entry with a different name that could as well be the culprit.
• Select the misbehaving app and tap Uninstall.
• Confirm removal on the relevant dialog box and reboot your device. By default, Android will get you back into regular mode. You should now be good to go – the Reverse Captcha pop-up won’t be triggering any redirects or irritating popups anymore.
Restore web browser settings to their original defaults
In the circumstances of a complex browser hijack like this, executing a reset makes the most sense despite a few obvious downsides. Customizations such as saved passwords, bookmarked pages etc. will be gone, but so will all the changes made by the potentially unwanted program. The instructions below address the workflow for the web browsers most targeted by the Reverse Captcha pop-up.
Reset Google Chrome
• Open Chrome, expand the Customize and control Google Chrome menu and choose Settings.
• Click Advanced in the sidebar, scroll down to Reset and clean up, and select this option.
• Click Restore settings to their original defaults.
• Finally, confirm the restoration by clicking Reset settings on the warning message.
• Restart Chrome.
Reset Mozilla Firefox
• Open Firefox, type about:support in the URL area and press Enter. Alternatively, you can click on the Open menu icon in the top right-hand part of the browser window, then select the Help option and proceed to Troubleshooting Information.
• On the Troubleshooting Information screen, spot the Refresh Firefox button and click on it.
• Follow subsequent directions to reset Firefox to its original settings.
• Restart the browser.
Reset Internet Explorer
• Select Internet options under IE’s Tools (Alt+X).
• Proceed by clicking on Advanced tab, then select Reset.
• To confirm the intended changes, click Reset on the Reset Internet Explorer Settings screen after ascertaining that the Delete personal settings checkbox is enabled.
• Reboot the machine to fully implement the fix.
• Go to the Safari menu and select Preferences.
• When on the Preferences screen, select the Privacy tab and hit the Manage Website Data button.
• Click the Remove All button to purge all website data. Be advised this will log you out of online services and undo personalized web browser settings such as saved passwords, etc. If you aren’t okay with this, proceed to the next step.
• Safari also allows deleting data for specific sites rather than all sites in general. To use this option, select the unwanted site in the ‘Manage Website Data’ list and click Remove. Then, click Done.
• Click the Develop menu in the Finder bar and select Empty Caches.
• Finally, expand the History menu from the Finder bar and click Clear History.
• Make sure all history is selected on the dialog that will appear and click Clear History to get rid of cookies and other potentially unwanted data.
• Restart Safari.
Revise your security status
Post-factum assessment of the accuracy component in malware removal scenarios is a great habit that prevents the comeback of harmful code or replication of its unattended fractions. Make sure you are good to go by running an additional safety checkup.
