SmartCaptcha

SmartCaptcha is a type of software application that looks like a regular browser extension for Windows-compatible browsing programs. Usually, SmartCaptcha gets embedded in the system in a very inconspicuous way and its presence comes as a surprise to users.

SmartCaptcha Virus
The SmartCaptcha Virus

This is because SmartCaptcha is what is known as a browser hijacker and these types of code are considered by most to be potentially unwanted programs or PUPs. In other words, there’s hardly a user out there who would actually prefer to have such software on their computer, as they don’t really offer any useful functionality for the end user. Furthermore, if anything they actually take away from one’s browsing experience by means of imposing their changes on the infected browsing program.

So whether you’re currently using Chrome, Edge, Firefox or some mainstream browser, you have likely already come to experience some rather obvious changes in its behavior and appearance.

Typically, software like SmartCaptcha or Smart Captcha will replace the default search engine with a new one and it may even set it as the new browser homepage. In addition, software of this type has a tendency to install ad-generating components in the browser in question, which enables it to display popups, box messages, banners and other types of online adverts directly on your screen during browsing sessions.

And if you are among the many users who have simply tried to change their browser settings back to their original state, then you’ve likely also discovered that it simply cannot be done. This is because as long as SmartCaptcha exists in your system, it will always override any changes you make to the configurations. And the developers of such software know that such behavior will rarely be greeted with open arms, so they hardly ever include an obvious uninstallation option. Instead, users have to try and remove the pesky ad-generating program manually, which is often more difficult than it may sound.

For this reason our team of professionals has compiled a free removal guide for SmartCaptcha, and you can find it on this page, just below the current post.

Other reasons you may want to remove SmartCaptcha

Being a typical PUP, SmartCaptcha provides more than just one reason for end users to want to uninstall it from their computers. And its annoying behavior is just scratching the surface of it.

In the long run, the presence of a browser hijacker like this one may result in a decreased quality of your computer’s overall performance. The constant generation of online ads and other background activities that SmartCaptcha may be running can consume a lot of your PC’s resources (read RAM and CPU), and that, in turn, could lead to overheating, system crashes, programs lagging and freezing up, etc.

But what’s even more harrowing is the potential of landing infections with viruses and malware as a result of SmartCaptcha’s activity. The frequent page redirects to dubious web locations may at some point land you on a page or website that’s been tampered with by hackers. And that could lead to attacks from highly dangerous malicious programs like ransomware and Trojan horse viruses.
