Cousonelly is a browser hijacking software that incorporates itself into popular web browsers like Chrome, Edge and Firefox, and turns them into ad-generating tools. Cousonelly cannot harm the computer in a direct way but may spam the users’ screen with irritating pop-up, banner ads and links that redirect to different pages.
Many browser hijackers tend to add some potentially unwanted components inside the system’s main web browser in order to facilitate the display of more sponsored ads, pop-ups, and links. Apps like Cousonelly, for instance, may add a new homepage, a new search engine or some other buttons and toolbars the role of which is to automatically redirect users to specific web locations full of pay-per-click ads and pay-per-view links.
The Cousonelly Virus
Browser Hijacking programs such as the Cousonelly virus typically don’t have harmful features, nor are they as problematic as Trojan Horse viruses or Ransomware infections. However, most security professionals, including our “How to remove” team, suggest you remove these apps as quickly as possible. There are several factors that support for this recommendation and, in the next lines, we will tell you about them.
The first and probably the most important think that you should take into account is the online dangers you may face thanks to the auto-redirects initiated by the browser hijacker. Cousonelly, and the programs of its kind ( Parrable, Main Captcha Top) are typically built to expose web users to various paid advertisements and pages that pay for traffic and promotion. That’s why, these programs will use various tactics to redirect you to such pages and make you click on their associated pop-ups, banners and promotional messages.
The main issue with this is that you can’t really say how trustworthy all the web links and ads that you get exposed to are. Among the numerous pages and blinking banners you would get to see on your screen, there could be pages and ads of questionable products and services, as well as misleading messages that may land you on phishing sites which may directly inject you with viruses and malware such as Ransomware, Trojans, Spyware, etc., as soon as you land on them.
Furthermore, the stream of nagging ads can hardly be removed or restricted and the same is valid for the newly installed homepage, search engine, and the other potentially unwanted browser components – they may not want to get uninstalled no matter how hard you try. Even a total reset of your browser may not be able to save you from the changes and the aggressive ads.
Keeping an app like Cousonelly on your computer could affect also the performance and the protection of your browser. Users who don’t do anything to uninstall the browser hijacker may have to endure multiple browsing issues, such as freezing of the screen, unresponsiveness, and sudden page-crashes which may seriously disturb the regular web surfing activity and make the browsing app unstable.
Fortunately, the salvation from the hijacker’s disturbance isn’t that complicated and even not so experienced users can deal with an app like Cousonelly as long as they follow certain instructions. Those who don’t want to follow the steps in the manual removal guide below can still select from a broad range of malware removal programs which can quickly scan the entire computer and remove the unwanted software.
|Danger Level||Medium (nowhere near threats like Ransomware, but still a security risk)|
|Symptoms||Various unauthorized changes to the browser, aggressive ads and pop-ups all over the screen.|
|Distribution Method||Browser Hijackers normally get distributed via different free software bundles, misleading online messages, torrents and spam.|
Some threats reinstall themselves if you don't delete their core files. We recommend downloading SpyHunter to remove harmful programs for you. This may save you hours and ensure you don't harm your system by deleting the wrong files.
