On this page, you will find useful information about the typical behavioral traits of this software, its methods of distribution and infection, as well as some handy tips on how to stay away from it. In case you want to remove this program, our team of professionals has prepared a removal guide for you, which will show you exactly how to remove the unwanted program step by step. If you follow the instructions below you will no longer need to deal with the strange changes that Claro Search has applied on your Chrome, Firefox or other default browser, and you will soon save yourself from its constant search engine redirects and unknown homepage.

What is the actual purpose of Claro Search?

You’re probably wondering what that strange activity that is constantly feeding your screen with annoying advertisements is and what the use of it is. Well, it is all about the big online advertising industry and money. Generally, browser hijackers are pieces of software, created mostly with the idea to generate income for their developers, rather than bring some actual benefit to the users, although some applications may claim to do so. Through remuneration schemes like Pay-Per-Click, the owners of Claro earn revenue every time you click on some of the intrusive advertisements that appear on your screen. That’s why they sometimes really overdo it with the amount of ads, pop-ups, banners and sponsored pages in their attempts to get more clicks. As a result, some users may get irritated and seek for ways to uninstall the software that is generating them, instead of tolerating the aggressively popping messages on their screen.

Is Claro Search a “Virus”?

Apart from being irritating, you should not expect any harmful actions from a program like Claro. It other words Claro Search is not a virus. Browser hijackers are not considered as dangerous as viruses, Trojans, Ransomware and other malware. In fact, they do not fall in the malicious category and it would be more accurate to refer to them as potentially unwanted programs, rather than viruses. The reason is that they are not directly related to any cybercriminal activities such as spying, data theft, encryptions or blackmailing, but they may still cause some system and browsing related inconvenience, which is potentially unwanted. For example, what a browser hijacker may do is, it may mess with the settings of your default browser and manipulate its search engine, replace the homepage and redirect you to various sponsored advertisements or web pages full of ads, pop-ups, and banners that don’t want to go away. This activity may result in slower system performance, lags, freezing screen effects and a generally slow loading of pages in your browser. The good thing is that, unlike the irreversible and harmful effects of malware like a Trojan or Ransomware, all this is nothing permanent. Once you completely uninstall the ad-generating component from your system, you will get back all your normal settings. 

How to uninstall Claro completely?

When it comes to its complete removal, you should know that such software may require some advanced system knowledge. The reason is that browser hijackers may often integrate their components deep inside the computer’s files, where detecting and manually removing them may be a bit tricky. But don’t get stressed because we did our best to explain the baby steps to the full removal of Claro in the guide below. In addition, you may find it helpful to deep scan your PC with the professional removal tool that will find and easily eliminate the annoying hijacker in just a few seconds.

Once you successfully uninstall it, make sure you keep such unwanted software away from your computer in the future. This could easily be done if you avoid downloading and installing software from locations like freeware platforms, open source download sites, torrent sites, direct downloads from the web, spam emails or different installation managers. Apart from free programs, they usually contain bundles that may eventually include potentially unwanted programs like Claro or other bloatware. If you attempt to install some software, you should always check what you are getting along with the given setup. To do that, simply click on the advanced/custom options instead of the standard one and you will be able to easily prevent any programs you may not want by simply unchecking their checkbox inside the bundle. This is a sure way to keep additional software away from your machine in the future.
