Luckily, Captcha-bros.com is only a mild infection and it only affects the browser. A few simple changes to browser settings can stop it easily (instructions for how to do that can be found below).

How does Captcha-bros.com work?
Captcha-bros.com is a website that sends notifications to web browsers. These notifications show up as little pop-ups labeled with “Captcha-bros.com”. They are advertisements for various products, from online marketplaces and popular VPNs to scams and malicious software.
The ads don’t start by themselves; Captcha-bros.com first has to get your permission to show you notifications. In most cases, that means that you must see a notification like the one below and then click the “Allow” button.
But why would anyone agree to receive notifications from Captcha-bros.com, a random site that has no content on it?
Here’s how Captcha-bros.com gets inside people’s browsers to push its ads:
- It is advertised online. Captcha-bros.com is promoted on sites that are infected with malware, as well as on sites that allow unsafe ads.
- Captcha-bros.com appears unexpectedly and asks the visitor to click the “Allow” button on the notification prompt. It lies about why the button needs to be clicked, making people feel like they have to do it.
The screenshot below shows what page of Captcha-bros.com I saw: it says that, in order to prove that I’m not a robot, I must click “Allow”.
Robot checks are pretty normal online (they might appear when loading a website, before downloading a file, or after repeating the same action on a website many times), and that’s what Captcha-bros.com wants – to look ordinary.
In reality, the Captcha-bros.com screen exists only to trick people into subscribing to its notifications. Just so it can send ads to their browsers and get money from the advertisers.
Captcha-bros.com is only one of many notification spammers that are out there; Codingcaptcha.com, Tableshop.xyz, Download-app.net, and many other sites are doing the same thing, trying to hijack browsers and send ads.
How to protect yourself from notification hijackers
Captcha-bros.com can affect any browser that supports notifications and allows notification prompts. You can curb it and similar sites by going into your notification settings and making it so that notification prompts are automatically hidden
For instance, Captcha-bros.com worked normally on my Chrome browser, but broke a little on my Firefox because it wouldn’t show the notification prompt.
As Captcha-bros.com only needs a browser that supports notifications to work, it can affect phones, computers, tablets, and other devices. Luckily, as browsers are easy to infect, they’re also easy to disinfect. It’s very simple to block unwanted ad spam by changing your browser settings.
In addition, you can block some malicious sites and programs with antivirus software such as Spyhunter for Windows, Spyhunter for Mac, Combo Cleaner for Mac, and others. Ad blockers can also protect you from malicious sites online.
How to stop Captcha-bros.com ad spam
Block notifications from Captcha-bros.com in your browser settings:

- Edge – open Settings, click Site Permissions, Notifications.
- Safari – in the Safari menu, choose Preferences, Websites, Notifications.

Take the opportunity to look at what other sites can send you notifications – you might want to block them, too. Only allow sites that you actually want to receive notifications from.
