Cup Extension Virus

Cup Extension

Cup Extension is a form of potentially unwanted software that will target your main browser, hijack its homepage and toolbar, and spam it with uncontrolled page redirects. Cup Extension is also likely to inject ads into the search results of the browser’s default search engine.

Such activity from a rogue app would likely seem like a serious problem to many users, especially to ones who have never before encountered similar browser-hijacking software. However, while the presence of Cup Extension in the browser should certainly not be ignored and overlooked, there is no need to succumb to panic and take drastic measures such as reinstalling/resetting your OS. In most cases, you won’t even need to take your computer to a specialist to fix your browser hijacker issue. Instead, to remove Cup Extension from your Chrome or Firefox (or other) browser, it should usually be enough to follow the instructions provided within the guide on the current page that you can find down below.

The Cup Extension Virus

The goal of rogue apps like the Cup Extension virus is mostly aimed towards making money through paid ads and site promotions, which explains why the Cup Extension virus would continuously put obstructive ads and redirect you to sites you did not intend to go to. You see, a browser hijacker isn’t necessarily a highly harmful piece of malware like a Trojan or a ransomware virus.

This activity earns income for the developer of the unwanted app on the basis of the Pay-Per-View model. In other words, each time you visit a page or a site that the hijacker is advertising, you’d be earning revenue for the creators of the hijacker. Of course, this doesn’t make things any better. Even if Cup Extension and Paper Extension isn’t actively trying to harm your system, you’d still be forced to put up with its advertising activities every time you start your browser, not to mention that some of the content that may get advertised on your screen might be less than safe.

As a matter of fact, the biggest problem associated with representatives of the browser hijacker category isn’t that they are annoying to have in the browser but that their uncontrolled site promotions and ad displays may eventually put your system at risk. There are certainly way more harmful forms of rogue software and malware on the Internet, including Trojan horses, file-targeting ransomware viruses, and stealthy data-stealing spyware infections but the main problem with Cup Extension is that you may actually get exposed to such threats should the hijacker be allowed to stay on your computer for long.

You need to remove Cup Extension

To stop the obstructive display of ads and the aggressive page redirects as well as to improve the overall security of your computer, we suggest that you take the necessary measures to uninstall the software that is behind all this. As we said earlier, we will help you do that with the below removal guide. It includes detailed manual instructions as well as a linked recommended removal tool capable of quickly locating and removing any data related to undesirable browser hijackers in the system.

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

If there are suspicious IPs below “Localhost” – write to us in the comments.

Open the start menu and search for Network Connections (On Windows 10 you just write it after clicking the Windows button), press enter.
