Robotcaptcha2.info "Virus" removal guide for windows and mac

The main goal of the Robotcaptcha2.info “Virus” is to make you subscribe to its Push notifications by displaying pop-up windows asking for permission.

A new Browser Hijacker application has been reported to our “How to remove” team recently. The name of the program is Robotcaptcha2.info and, according to the reports, popular browsers such as Firefox, Chrome, and Explorer have been affected by it. If you are on this page because you have noticed a change in your homepage and/or in the default search engine, or a stream of aggressive ads, pop-ups, banners and redirect prompts, and all of them are “Powered by Robotcaptcha2.info”, then stay with us to learn how to remove these changes and uninstall the program that is causing them.

To your relief, Robotcaptcha2.info “Virus” is not some nasty virus, a Spyware, a Trojan or a Ransomware infection. That’s why you have a good chance to deal with it just by using the instructions and the removal tool in the removal guide below. In any case, even if the Browser Hijacker is not a harmful program, you may want to uninstall it as soon as possible because the longer it remains in the system, the more irritation and disturbance it may create. For instance, you may start to notice that your computer runs slower than normal, your browser becomes unresponsive to your searches and you start to see too many unwanted ads in pop-up windows, that redirect you to suspicious websites. This is something typical for those programs because they basically operate as online advertising tools that promote sponsored content.

When the users enter a search query in their browsers, the job of the hijacker is to open a sponsored web address, some pay-per-click ad or a banner first and only then to display the search result. In summary, this app causes unwanted redirects and spams the screen with advertisements, some of which may even be questionable.

How was Robotcaptcha2.info installed on my computer?

It is possible that Robotcaptcha2.info could be promoted in some supposedly official page that you have visited. However, it is quite common for most web users to download and install such applications without wanting to, mostly through software bundles. The developers distribute the unwanted apps by packing them into the download wizards and installers of other software. To be more concrete, they do this by hiding the hijacker in the “customized” or the “advanced” settings and other similar settings of installation wizards, and by not indicating this information as it should. The easiest way to be tricked into downloading and installing Browser Hijackers and other ad-generating programs is if you do not pay attention to the settings mentioned above in the wizards. However, this is not the only way to end up with a program like Robotcaptcha2.info, Cloudnet or “Pornographic Virus Alert from Microsoft”. Sometimes it takes just a few clicks on several intrusive ads for some unwanted downloads and installations to be initiated. That’s why we strongly recommend downloading software only from official and reliable websites and not from third-party downloaders, installers, torrent or download clients (or other P2P networks), and unofficial websites, etc. Another important thing is to verify all custom or advanced settings and other small checkboxes and “bonus” programs that are available in any software installer. Also, avoid clicking on intrusive ads, especially if they appear on some suspicious and unofficial websites. These ads may cause redirects to different questionable pages (including sites infected with Trojans or Ransomware) or initiate the download and installation of unwanted apps.
