reCAPTCHA – Google
What is reCAPTCHA?
reCAPTCHA protects your website from fraud and abuse without creating friction.
reCAPTCHA uses an advanced risk analysis engine and adaptive challenges to keep malicious software from engaging in abusive activities on your website. Meanwhile, legitimate users will be able to login, make purchases, view pages, or create accounts and fake users will be blocked.
Proven
reCAPTCHA has been at the forefront of bot mitigation for over a decade and actively protects data for our network of five million sites.
Frictionless
A seamless fraud detection service that stops bots and other automated attacks while approving valid users.
Adaptive
reCAPTCHA’s risk-based bot algorithms apply continuous machine learning that factors in every customer and bot interaction to overcome the binary heuristic logic of traditional challenge-based bot detection technologies.
Scraping
Content pilfering for ad revenue diversion or competitive use
Fraudulent Transactions
Purchase of goods or gift cards with stolen credit cards
Account Takeovers (ATO)
Credential stuffing to validate stolen accounts
Synthetic Accounts
Creation of new accounts for promotion value or future misuse
False Posts
Posting of malicious links or misinformation propagation
Money Laundering
Bot generated ad click revenue on fraudulent websites

How does the “I’m not a robot” checkbox work? – Medium
Asking you to click a checkbox to confirm that you are, in fact, human seems curiously today’s age, there’s a high chance that you, dear reader, are a machine. Maliciously-programmed internet bots (software applications that can run automated tasks) are an unfortunate commonplace on the internet. They can be used at various scales from generating fake social media accounts, to rapidly booking out all tickets for a popular concert and orchestrating a large-scale Distributed Denial of Service (DDoS) attack; a DDoS is an attempt to make an online service unavailable by overwhelming it with traffic. It’s the type of high-profile attack that can take down everything from banks to government websites. A dystopian world like this needs a reliable way to differentiate an evil bot from a well-intentioned human. How can a banking website be sure that an innocent grandma who is logging in to check that the holiday gift money was successfully transferred to her grandchildren, is in fact, an innocent grandma? Enter, the “Completely Automated Public Turing test to tell Computers and Humans Apart”, or more simply, the like internet bots themselves, and like much of the innovation on the internet, CAPTCHAs find their origin in the hacker community. Back in the ancient 1980s the hackers invented leetspeek to bypass security filtering on internet chat forums. Leet is a method of converting words to lookalike characters or abbreviations that cannot easily be interpreted by a computer:leet > I33tcensored > c3n50redporn (pornography) > pr0nIn the pre-Google days of the internet, websites would be manually submitted to search engines. In order to prevent the submission of fake websites, AltaVista implemented the first CAPTCHA-like system that required a user to type a series of distorted characters into a box. This approach, which we often still encounter when registering new accounts or submitting information on the internet, is based on three principles:Humans can more easily recognise highly distorted, rotated or skewed can more easily visually separate overlapped can more easily draw on context to understand visually distorted characters, for example, identifying a character based on the full word that it appears search engine Alta Vista was one of the first popular websites that introduced a CAPTCHA-like protection when submitting new websites to its 2003, a research team from Carnegie Mellon University published a pioneering research paper that described many different types of software programs that could distinguish humans from computers. It was this group that also coined the catchy acronym. As CAPTCHAs became a status quo of security on the Internet, Luis von Ahn, a member of the original research team, became increasingly uncomfortable with how much valuable time was being wasted on solving these mini puzzles. In a wonderful 2011 TED Talk, von Ahn estimated that humanity as a whole was wasting 500, 000 hours a day on completing Von Ahn discusses how the collective amount of time wasted on filling out CAPTCHAs inspired the reCAPTCHA ioning whether this time could be put to more powerful and meaningful use, he developed reCAPTCHA, which was eventually sold to Google in 2009. These days, there are a number of projects and companies (including Google Books, the Internet Archive, Amazon Kindle and The New York Times) that are scanning and indexing large numbers of books, documents and images for use on the web. reCAPTCHA works by taking any of the scanned words that cannot be recognised and presenting them to a human alongside a known word for interpretation. By typing the known word correctly, you identify yourself as a human and the reCAPTCHA system gains some confidence that you have correctly digitised the second. If 10 other people agree on the transcription of the unknown word, the system will assume this to be correct. Today reCAPTCHA helps to digitise millions of books a year and has also extended to support other efforts like digitising street names and numbers on Google Maps or recognising common objects in photos for Google original reCAPTCHA asks you to type a known scanned word to identify yourself as a human and to help transcribe another word that a computer was not able to forms of CAPTCHAs are also being used to help index images and data captured by Google Street are many other forms of CAPTCHAs, including an audio version for the visually impaired. But it is the curiously simple variety — the “I’m not a robot” checkbox seen on many of today’s websites — that inspired the original question behind this article. This checkbox, endearingly called the “no CAPTCHA reCAPTCHA”, is a Google product that unsurprisingly uses a combination of advanced Google technology to produce a very simple result. Google will analyse your behaviour before, during and after clicking the checkbox to determine whether you appear human. This analysis might include everything from your browsing history (malicious bots don’t necessarily watch a few YouTube videos and check their Gmail before signing up for a bank account), to the way you organically move your mouse on the page. If Google is still unsure of your humanness after clicking the checkbox, you will be shown a visual reCAPTCHA (with words, street signs or images) as an additional security measure. This multi-faceted approach is necessary as computers become more skilled at complex image recognition and with the rise of CAPTCHA sweatshopping (think a large room of underpaid workers tasked with generating a heap of fake social media accounts).

Why am I seeing the pop-up ads?
You are seeing the advertisements because your computer is infected with a malicious program or a site that you have visited has redirected you to this page.
Less than reputable sites can display malicious ads that redirect your browser to the pop-up ads to generate advertising revenue. If this happens, you can close the page and install a free browser extension like Adblock to block the malicious ads. However, if you are continuously seeing pop-ups like the pop-up ads, then your computer might be infected with a malicious program and you need to scan your device for adware and remove it.
Here are a few typical signs that you have a malicious program installed on your computer:
Advertisements appear in places they shouldn’t be.
Your web browser’s homepage has mysteriously changed without your permission.
Web pages that you typically visit are not displaying properly.
Website links redirect to sites different from what you expected.
Browser popups appear which recommend fake updates or other software.
Other unwanted programs might get installed without your knowledge.
To check your computer for the adware and remove it for free, please use the guide below.

To remove the advertisements changes from Chrome we will reset the browser settings to its default. However, your saved bookmarks and passwords will not be cleared or changed.
Open Chrome’s “Settings” menu.
Click on Chrome’s main menu button, represented by three horizontal lines. When the drop-down menu appears, select the option labeled “Settings“.

That’s it. The pop-up ads should be gone from your Chrome browser.
If the above steps didn’t help you remove the pop-up ads from Chrome, you can follow the below steps:
Remove the unwanted policies created by malware from Chrome
In many cases, changes to Chrome may not be fixed with a simple browser reset. In such a case, it’s very possible that a malicious program has created unwanted policies on your browser. You can check if any unwanted policies are loaded into the browser by typing chromepolicy into the URL bar.
To reset these policies, follow these steps:
Open a new Terminal window. To do this, go to Finder > Go > Utilities > Terminal
Enter the following commands, pressing enter after each line:
defaults write HomepageIsNewTabPage -bool false
defaults write NewTabPageLocation -string “
defaults write HomepageLocation -string “
defaults delete DefaultSearchProviderSearchURL
defaults delete DefaultSearchProviderNewTabURL
defaults delete DefaultSearchProviderName
defaults delete ExtensionInstallSources
After running these commands, quit Chrome if you haven’t already done so, then launch it again and check chromepolicy to see if the same keys are still present (you may need to click the “Reload policies” button for changes to show up). If they’re gone, you should be able to change your search engine and home page back to your preferred defaults in Chrome’s settings.
Remove the “Managed by your organization” policy from Chrome
Some malicious programs are known to install managed preferences to set the home page and search engine settings in Chrome. To check for these, do the following:
Quit Chrome
Click the desktop to make sure you’re in the Finder, choose “Go” then click on “Go to Folder“.
Type or copy/paste the following path into the window that opens, then click Go: /Library/Managed Preferences/
Paste the below path into the window that opens, then click Go:
Look for the following files, where [username] is your username:
[username]/
These may be legitimate, so open these files with TextEdit and see if they have links to the troublesome site in them. If they do, delete them and restart Chrome.
Uninstall Google Chrome from your computer
If the above options didn’t help you remove the malicious redirects, it is easier to completely remove Chrome and all data, then reinstall the browser. To do this, click the Finder icon, from the menu bar. Choose Go, and click Go to Folder, then paste one of the below paths into the window that opens.
You will need to delete all of the below items, but before doing this be aware that this will delete all data for all Google apps you have installed, such as your bookmarks, so you will need to export them before doing this.
/Applications/
/Library/Application Support/Google/
/Library/Google/
~/Library/Application Support/Google/
~/Library/Google/
~/Library/Preferences/
Note: The “~” indicates that it’s the current user’s Library which is often invisible in recent versions of macOS. To get to it you must hold down the Option (sometimes labeled Alt) key down and select Library from the Finder’s Go menu.
After deleting all of the above files, restart your device. You can now download and re-install Google Chrome on your device. You will need to import any exported bookmarks or other data, and may need to reinstall any other Google apps that you use.
Remove pop-up ads from Safari
To remove pop-up ads from Safari we will check if there are any malicious extensions installed on your browser and what settings have been changed by malicious programs.
Go to Safari’s “Preferences”.
On the menu bar, click the “Safari” menu and select “Preferences”.
Check Homepage.
This will open a new window with your Safari preferences, opened to the “General” tab. Some pop-up adss may change your default homepage, so in the Homepage field make sure it’s a web page you want to use as your start-up page.
Click “Websites”
Next, click on the “Websites” tab, then in the left menu click on Notifications. Find the site and select it, click the Deny button.
Click “Extensions”
Next, click on the “Extensions” tab.
Find and uninstall the malicious extension.
The “Extensions” screen will be displayed with a list of all the extensions installed on Safari. Scroll through the list until you find the malicious extension, and then click on “Uninstall” to remove it. By default, there are no extensions installed on Safari.
Look out for any suspicious extension that could be behind all the drama – anything you don’t remember installing or that doesn’t sound like a genuine browser extension. Here are some known malicious extensions: TakeFresh, TopResults, FeedBack, ApplicationEvents, GeneralOpen, PowerLog, MessengerNow, ImagePrime, GeneralNetSearch, Reading Cursors, GlobalTechSearch, PDFOnline-express, See Scenic Elf, MatchKnowledge, Easy Speedtest, or WebDiscover.
If the above steps didn’t help you remove the pop-up ads from Safari, you can follow the below steps:
Workaround for greyed out Safari’s homepage
In some cases, after being changed by pop-up adss or malware, Safari’s home page can become stuck (greyed out). You will be able to edit the Homepage field in Safari’s preferences, but the change will not stick. This appears to be a bug, and there is an odd workaround. Try this:
In Safari, choose Preferences from the Safari menu.
In the window that opens, click the General icon (if necessary)
Enter your desired home page in the “Homepage” field, but DO NOT press return!
At the top of the window, click any of the other icons (eg, Tabs, AutoFill, etc).
You may see a prompt asking for confirmation for changing the home page. If so, confirm.
Switch back to the General page and check to make sure the home page has been changed.
Delete Safari’s preferences file to remove malicious changes
Some malicious programs are known to install managed preferences to set the homepage and search engine settings in Safari. If the above options didn’t help you remove the malicious redirects, we’ll need to delete the Safari’s preferences. To do this, follow the below steps:
Quit Safari
Type or copy/paste the following path into the window that opens, then click Go: ~/Library/Preferences/
If the file is found, delete it, then re-open Safari
To remove the pop-up ads from Firefox we will reset the browser settings to its default. The reset feature fixes many issues by restoring Firefox to its factory default state while saving your essential information like bookmarks, passwords, web form auto-fill information, browsing history, and open tabs.
Go to the “Help” menu.
If you’re unable to access the “Help” menu, type about:support in your address bar to bring up the Troubleshooting information page.
Click on “Finish”.
Firefox will close itself and will revert to its default settings. Click on the “Finish“.
Your computer should now be free of the pop-up ads. If your current antivirus allowed a malicious program on your computer, you may want to consider purchasing the full-featured version of Malwarebytes Anti-Malware to protect against these types of threats in the future.
If you are still experiencing problems while trying to a malicious program from your computer, please ask for help in our Mac Malware Removal Help & Support forum.

STEP 2: Remove pop-up ads from your browser
In this final step, if the advertisements are still present on your phone, we will need to reset the web browser settings to their original defaults. This step should be performed only if your issues have not been solved by the previous steps.
Resetting the browser settings to their default it’s an easy task on Windows or Mac computers; however, when it comes to Android, this can’t be done directly because it’s not an option built-in into the browser settings. Restoring the browser settings on Android can be done by clearing the application data. This will remove all the cookies, cache, and other site settings that may have been saved.
