Three Captcha

Three Captcha is a potentially unwanted program that modifies the web browser’s settings without users’ consent. The purpose of Three Captcha is to put paid advertisements on the screen during browsing sessions.

If you are on this page, you’ve most likely discovered some odd changes to the homepage and/or the default search engine of your Chrome, Edge or Firefox browser or you’ve been getting bombarded by a massive amount of ads, pop-ups, and banners as you’ve been trying to browse the web. These are all common indicators of the presence of a browser hijacker such as Three Captcha on your computer, without counting the less frequently observed ones that might include screen freezing, browser unresponsiveness, sudden crashes, and longer page loading times. In this article, however, we’ve prepared a detailed removal guide that will help you uninstall Three Captcha and remove all the nagging ads and browser changes once and for all. So, in case you are desperate to bring your browser’s settings back to normal, just stick to our guide and follow its instructions.

ThreeCaptcha

ThreeCaptcha don’t typically have the ability to replicate itself like computer viruses, steal sensitive information from you like Trojans, apply encryption or delete your files like Ransomware, or do some other harm. Nevertheless, such programs, including new representatives like the ThreeCaptcha, Lookaside.fbsbx.com, Hutters.click may expose you to some security risks that you should be aware of, especially if you are wondering whether to uninstall this software from your PC or not.

For instance, the advertisements the browser hijacker may display are something you must not disregard as a mere annoyance. With the increased popularity of malvertisements as a means of virus distribution, ads have become a major carrier of various stealthy infections such as Ransomware, Trojans, and Spyware. And the fact that hundreds of aggressive ads, links, pop-ups, and misleading messages can show up on your screen thanks to a program like Three Captcha means that there is always a risk of accidentally landing on a malicious or misleading message.

The ThreeCaptcha.top Virus

Now, it is unlikely that the ThreeCaptcha.top virus will deliberately redirect you to malicious advertisements or do anything to expose you to danger. However, cyber criminals tend to target genuine advertising messages and insert malicious software into them without no one knowing about that. Such ads can then circulate around the web, and sneak inside the stream of ads generated by programs such as the ThreeCaptcha.top virus.

The worst part is that there is no way to detect those malvertisements or the infections they transmit before it is too late because they typically look absolutely legitimate.

With the above in mind, our best advice is for you is to avoid interacting with any online ads, links, or banners that have randomly popped up on your screen. With a browser hijacker in the system, however, avoiding ads can be difficult, if not impossible. That’s why we recommend you use the removal guide below to safely detect and remove Three Captcha from your system. This will also enable you to regain control over your default web browser and restore all your previous web browsing settings.

Even if browser hijackers like Three Captcha aren’t intended to harm your computer, it is always a good idea to check the system for any signs of hacking. This can be done in the Hosts file and here is how to open it:

Hold together the Start and R keys from the keyboard and copy the following command in the Run box that pops up on the screen:

notepad %windir%/system32/Drivers/etc/hosts

Press Enter from the keyboard and the Hosts file will open. This is a simple text file that you can scroll. Go to the bottom of the file where it is written Localhost. In general, there shouldn’t be any questionable IP addresses below Localhost but if you see any, just as it is explained in the image below, this might be a sign that the computer is hacked.

If there are IP below “Localhost” that are bothering you and seem questionable, please write to us in the comments so we can assist you.

Next, click on the start menu of the computer and search for Network Connections. Open it and right-click on the Network Adapter you are normally using. Then, from the menu that appears select  Properties. Once the Ethernet Properties window appears, select > Internet Protocol Version 4 (ICP/IP), and click on the Properties button as shown in image 2 below. After that, set the DNS  to Obtain DNS server automatically and then click on the Advanced button. Next, in the new window tap on the DNS tab and remove the rogue DNS in the field. Click OK to confirm the changes.

Browser hijackers like Three Captcha may add some entries in the Registry that need to be deleted if you want to fully remove the annoying program from the system. For that, open the Registry Editor (type Regedit in the windows search field and press Enter) and once you get there, open a Find box (press CTRL and F keyboard keys) where you can type the Name of the browser hijacker. Click on Find Next to search for entries with that name in the Registry and delete any results that are found with that name.

If no entries are found in this way, go to the directories below and delete or uninstall them:

• HKEY_CURRENT_USER-Software-Random Directory. 
• HKEY_CURRENT_USER-Software-Microsoft-Windows-CurrentVersion-Run-Random
• HKEY_CURRENT_USER-Software-Microsoft-Internet Explorer-Main-Random
