Captcha Less Top

Captcha Less Top is often viewed as a potentially unwanted piece of software belonging to the category of browser hijackers. The reason is Captcha Less Top can integrate with almost any browser and modify its settings without asking for approval.

In case that a software application named Captcha Less Top has nested inside your system, then you are very likely to encounter  constant ad-related interruptions (pop-ups, banners and redirect prompts all you’re your screen) during the time you surf the Internet.  After all, most apps like Captcha Less Top aim to make money for their developers through paid online advertisements and auto-redirects to sponsored websites.

The main problem is that the way they accomplish this is usually quite aggressive and the end users typically are forced to experience a number of unauthorized activities and browser changes. Most commonly, the search engine of the main web browser (Chrome, Firefox, Safari or another one) gets replaced with some new one that constantly displays sponsored search results. The same often happens with the homepage  – a new URL replaces the preferred one and gets automatically loaded when you open a new tab. In addition, the invasive software starts redirecting the users’ searches to various web locations, and that without them clicking on anything that would normally trigger a redirect of any kind.


Screen-wide ads, hard-to-remove pop-ups, colorful banners and hundreds of new-tabs may also interfere with your browser’s usage. All this the CaptchaLess.Top virus do with the sole purpose of generating higher profits from the clicks on the various types of ads to which those pieces of software subject their users.

The term “browser hijacker” may sound frightening to some users and may make them think of this software as scary ransomware or a Trojan horse virus, but the truth is that there is far less risk in finding a hijacker in your device than it is in actually getting your machine compromised with some real virus like a ransomware cryptovirus or a Trojan-based infection.


Nonetheless, having your favorite web browser modified by a browser hijacker like CaptchaLess is still upsetting, which is why we agree that uninstalling the unauthorized app and deleting any modifications it may have imposed to the browser is the best way to handle this software.

There could still be certain risks!

While Captcha Less Top is not a virus or anything close to malware, this app should still not to be fully trusted and should better be uninstalled. Its primary goal is to display as many pay-per-click advertisements as possible and to make you click on them in order to generate revenue for its developers.  That’s why the app may often be less than picky with the promotional content it displays and may actually generate and prompt you to click on some unrealistic online offers, misleading web links, fake pop-ups or poor-quality banners. You may often find yourself being tricked to visit a given interesting web link only to realize that you have actually been redirected to  a sketchy page that has nothing to do with the ad you were initially interested in.

Of course, if you remove the intrusive hijacker from your system with the help of the instructions below, you will greatly reduce the temptation of clicking on something misleading as well as the risk of landing at a dangerous web address.
