How to remove Captchafair.top virus

What is captchafair.top virus

captchafair.top refers to the ads the site spams on users’ desktops when it’s given permission to show notifications. It’s not difficult to see why users dealing with this issue may refer to it as captchafair.top virus but that classification is not technically correct. The site is merely misusing a legitimate browser feature that allows sites with permission to show notifications. But instead of showing useful content, captchafair.top just spams ads. If you’ve given captchafair.top permission, you shouldn’t interact with the notifications because you might be exposed to potentially malicious content, including malware. You should revoke the site’s permission to show notifications as soon as possible, for your own sanity.

The “show push notifications” feature is perfectly safe to use, despite the frequent abuse by questionable websites. If you regularly visit a particular website, you can give permission for it to show notifications. If you give a news website permission to display notifications, for example, you will get news alerts right on your desktop. You would be led directly to the news articles if you clicked on those notifications. So the feature does have its uses. If you decide you no longer want to see the notifications, you can easily stop them. If you are unsure about what to do, we have provided instructions at the very end of the report.

It should come as no surprise that dubious websites like captchafair.top routinely abuse this feature. They use it successfully to spam users with ads. When you get redirected to the site, you will see an image of a robot and a message saying you need to allow notifications to confirm you are not a robot. You will also see a browser alert saying “captchafair.top wants to show notifications”. If you allow this site to display notifications, advertisements will start to appear on your desktop. Avoid clicking on those ads if you have given the site permission because you could be exposed to scams and malicious software. Fortunately, revoking this permission is easy.

If you frequently find yourself being redirected, your computer may have adware installed. We advise doing a computer scan with anti-virus software just to be safe. It’s also possible that you are redirected by the websites you browse. In which case you can just install an adblocker program.

Redirects may signal an adware infection

Users commonly find themselves redirected to websites like captchafair.top when browsing risky websites. Because of the advertisements they host, it is not a good idea to access some websites without an adblocker application installed on your computer. Websites with pirated or pornographic content, for instance, are typically labeled as high-risk since they not only display questionable ads but also trigger redirects. However, these types of redirects are easily avoidable with an adblocker program.

If you notice that you are being redirected more frequently, even when browsing secure websites, your computer may be infected with adware. Adware is one of the most common infections that are installed through the software bundling method. Such infections may be added to free software as extra offers and permitted to install alongside without requiring explicit permission. This happens without users even knowing about it. Anti-virus vendors frequently flag programs that use this technique as potential threats because it is a pretty sneaky installation method.

Although these offers are theoretically optional, because they are hidden, users simply do not notice them and cannot deselect them. But if you know how to correctly install free programs, blocking these unwanted installations is very easy. When installing free software, be sure to select Advanced (Custom) settings rather than Default. The installation window will suggest you use Default settings, but those settings will hide all offers and allow them to install. However, if you choose Advanced settings, all offers will be visible. You will also have the option to uncheck all of them. Simply uncheck the boxes of those offers to stop their installation. It’s always a good idea to deselect every offer in order to keep your computer free of unwanted programs that might be difficult to remove. It is much simpler to prevent these infections from installing by unchecking a few boxes.

How to remove captchafair.top virus

Anti-virus software should be used to check your computer for an adware infection if you frequently get redirected. If adware is to blame, the only way to stop the redirects is to get rid of it. Using anti-virus software makes the removal process much simpler than if you did it manually yourself. To avoid annoying pop-ups and redirects, especially when visiting risky websites, install an adblocker tool.
