What is Maincaptchasource.com

Maincaptchasource.com stands for one of the rogue-type domains that are meant to penetrate adware into your computer via fake push-notification pop-ups appearing in the upper part of a page. Usually, you can see this type of pop-ups when entering unwanted pages that cause a chain of intermediate landing pages that force you into clicking on the “Allow notifications” button, therefore, unlocking the access to the website you were inclined to enter initially. Beware of clicking on this notification when you see messages like “Click on Allow button to continue browsing” or “Click Allow to continue”. Because once you allow receiving push notifications it will, therefore, start displaying deceptive ads right on your desktop that may contain redirects to malicious websites and other unwanted resources which increases the odds of getting infiltrated by some poor software. In case malicious ads did not terrify you, then keep in mind that adware can also track your location and gather a dozen of other information like passwords and browser activity that can be taken over to third parties or other nasty figures. Make sure you read and do the necessary actions to remove Maincaptchasource.com from your computer in the article below.

How Maincaptchasource.com infected your computer

As mentioned in the description above, it is usually spread via suspicious push notification pop-ups when crossing between different websites. However, hijackers also resort to a so-called bundling method (when malicious adware is delivered alongside other unwanted applications). Knowing that users misuse skipping the steps of installation, they hide supposedly legitimate software within “Custom” or “Advanced options” sections of these procedures. When you finish the installation you will inadvertently realize that there was something else installed on your computer. Adwares can make a lot of trouble by stealthily stealing your personal information for generating profit. Luckily, this is not a tough-removing type of software. It can be easily uninstalled from your PC by complying with the steps mentioned in the underneath section. To block ads and pop-ups use special ad-blocking utilities, for example, AdGuard (AdGuard for Mac). Here are all of the steps to remove Maincaptchasource.com ads from your computer below.
