CleverCaptcha Virus


CleverCaptcha is known for introducing certain changes to your Chrome, Firefox or other browser and subjecting users to a ceaseless display of nagging ads. Hence, CleverCaptcha falls under the browser hijacker software category.


The virus can place a new search engine tool, in your browser

Browser hijackers are applications that initially look like regular add-ons for your browsers but once they get installed on your computer, you’d quickly realize that they are probably not something you’d want to have on your PC. A hijacker can place a new search engine tool, a new toolbar and a new homepage and new-tab page in your browser without asking for your approval. It can also redirect you to all kinds of weird and unknown web locations as well as spam your screen with different pop-ups, blinking boxes and other advertising materials that would likely make your browsing experience quite unpleasant and maybe even frustrating.

CleverCaptcha, for instance, is a browser hijacker app that has been recently released and currently its creators are seeking to get it installed onto as many PCs as possible as that would increase the revenue gained from the ads displayed by the hijacker. This is, in fact, what the main purpose of most apps like CleverCaptcha seems to be – to advertise things and to earn money through the ads.

Naturally, in order to get more money, hijackers tend to be rather aggressive in their advertising techniques. Their ads can really get on your nerves since they are likely to pop-up most of the time during your browsing sessions. Also, the changes to the browser have their purpose as well. The new search engine will likely show you sponsored results and results have been modified in order to push certain sites, pages and products as a way of advertising them. The new new-tab page and homepage are also a way of advertising a given page. All in all, hijackers like CleverCaptcha are multifunctional tools for generating revenue through web-advertising and since there’s usually little to nothing that the end-user could benefit from them, removing them is usually the best option.

The removal guide on this page and the anti-malware tool that we’ve included in it will help you get rid of CleverCaptcha. However, some of you might be wondering if it really is that necessary to remove the hijacker. Many users out there are in fact not overly bothered by the nagging ads, page redirects and browser changes and are thus able to put up with the hijacker’s presence.

If you are of the same opinion, then you need to know something. Browser hijackers are not viruses, they are not like ransomware or Trojan horse infections. However, they are not very safe either. The control over the ads and the pages you might get redirected to is oftentimes non-existent, meaning it’s possible some of those pop-ups, redirect links, banners and so on might originate from shady sources. Oftentimes, it only takes a few clicks for you to get your computer targeted by some nasty virus like spyware, rootkits, ransomware or a Trojan.

That is why it’s advisable you do not interact in any way with the advertising materials that CleverCaptcha or any other browser hijacker might try to put on your screen no matter how appealing and interesting the advertised offers might appear. In this line of thinking, the best way to stay away from the ads is to get rid of their source which brings us back to the importance of using the instructions from this page or the removal tool and remove the undesirable software piece.
