Mahaidroagra is a web-browser add-on that can create a lot of disturbance to the users’ regular web surfing activity. For instance, Mahaidroagra can establish control over the main web browser and force it to display banner ads and redirect prompts that cannot be removed.


The purpose of the Mahaidroagra virus is to use your browser to show you as many ads as possible

You probably found this article because each time you try to load any new page in your browser an unstoppable stream of pop-up commercials, banners, text links, and colorful box messages start to flood the screen and prevent you from web browsing. This is a sure sign that you are probably dealing with a browser hijacker like Mahaidroagra. That’s why, in this post, we will explain to you how to deal with this particular program and how to uninstall it from your system without it causing more unwanted modifications.

As a new addition to the browser hijacker class, the purpose of Mahaidroagra and Top Captcha Solver is to use your browser (Chrome, Edge, Mozilla, etc.) to show you as many ads as possible and to make you click on as many partnering links as possible. This is basically how the program makes money for its developers – it displays pay-per-click advertisements and reroutes user searches to sites that pay for traffic and promotion. In order to operate more effectively, Mahaidroagra is known to change the browser’s homepage with a new one and to replace the homepage web address with one of its sponsored URLs. In the next paragraphs, we will go a step closer to describing the behavior of this browser hijacker and the security questions that may arise as a result of its activities.

What should you know about browser hijackers in general?

Browser hijackers are online advertising programs that may spread in a number of different ways, including as part of a torrent, as part or of a free software package, as an attachment in a spam email or via websites that distribute freeware and shareware. Developers use these programs to generate pay-per-click profits for promoting different apps, services, and products and redirecting web traffic to their related websites.

In general, browser hijackers are not malicious and are not capable of crashing the system like a Trojan virus or blocking access to vital data like a Ransomware infection. Yet, many web users consider such programs to be potentially unwanted and seek effective methods to remove them.

This is because letting a program like Mahaidroagra operate inside your computer may have some rather unpleasant effects. Firstly, Mahaidroagra and all the other programs of the browser hijacker class may generate so many advertisements, pop-up notifications, banner messages and colorful offers on your screen that it may be impossible to remove them and use your browser normally. Besides, the performance of the affected browser may also be affected. For instance, it can become more sluggish and unresponsive to your search requests or even freeze and crash due to ad overload.

Another very annoying reason to uninstall Mahaidroagra is that this program can spontaneously redirect you to pages that you never wanted to visit or are just irrelevant. This redirect activity can not only be very annoying and time-consuming but could also lead you to unsafe or suspicious Internet addresses where viruses, Trojans, Ransomware and other online infections may lurk. Therefore an essential step towards an enjoyable online experience is to uninstall Mahaidroagra with the help of the removal guide below and restore your browser’s favorite settings.
