Campaign Notifier Malware

Browser hijacker applications like the Campaign Notifier Malware are very common on the Internet and you can get one such app installer on your machine without even realizing it at first. However, sooner rather than later the signs and symptoms will start appearing and then you will see that the homepage or new-tab page of your browser has been replaced and that the same has happened to your browser’s default search bar.

It is likely that you will also start experiencing different kinds of browsing disturbance caused by nagging ads, redirects to different web locations, flashing banners, pop-ups and other kinds of pesky advertising materials. This could affect any browser – you could be using Firefox, Google Chrome, IE, Opera, Edge or some other browsing program and if you get a hijacker app installed on your computer it will more than likely be able to latch onto your browser and start flooding it with its intrusive contents and making unauthorized changes to it. Naturally, such irritating activity can heavily affect your regular browsing activity and make it difficult to navigate through the Internet and do whatever it is that you are trying to do online. Due to this, it is widely accepted that hijacker apps fall under the category of PUPs/PUA’s (potentially unwanted programs/apps). Therefore, most users who get faced with hijacker app on their computers are eager to get it removed as soon as possible so that the intrusiveness caused by its activity ceases. However, eliminating such a software might oftentimes require additional steps aside from simply pressing the uninstall button. That is why we have made sure to offer our readers with a more detailed suggestion on how to get rid of a hijacker app. In this case, we will show you how to handle Campaign Notifier “Malware” which is a newly developed and released browser hijacker that many users are currently struggling to remove. If you have this pesky app on your machine and don’t know how to eliminate it, the guide below is just the thing that you’d need in order to get rid of the irritating browser page-redirecting application. Just scroll down to the guide once you’ve finished reading this article and implement the steps – Campaign Notifier “Malware” should be gone in no time.

The Campaign Notifier Window

Campaign Notifier Window is actually not some nasty virus and it is very different both in purpose and in functionality from real malware threats the likes of Trojans, Worms, Ransomware, Spyware and so on. Despite that, many users normally see hijackers like this one as some kind of dangerous and highly harmful programs when in reality most browser-hijacking apps are relatively safe and are not really capable of causing any direct harm to the computers they’ve been installed on.

Notice, however, how we said that hijackers cannot cause direct harm. Despite their relatively safe nature, the ads and redirect pages that such apps could generate on your screen might not always be reliable. We advise you to keep away from anything that Campaign Notifier or any other hijacker might try to put on your screen. There are many shady and obscure advertising networks out there and a hijacker might sometimes stream ads and other promotional materials from such networks to your browser. Thus, interacting with the wrong ad might make your PC exposed to various types of online hazards and you might risk getting your machine infected with insidious and noxious cyber threats like Trojans and Ransomware. It is simply better to avoid interacting with hijacker-related content if you want to ensure that your machine stays safe. Besides, there are already enough ads on the Internet as it is so there’s hardly any need to allow the hijacker’s promotional contents to get in your way.

How do such apps find their way inside people’s computers

When installing a new program, which is the setup option that you normally choose? The majority of users would typically say that they tend to go for the Quick install as it is more convenient. However, this is actually a mistake that hijacker developers oftentimes use in order to ensure that their products get to as many PCs as possible. You see, if you go for the Quick install every time, you’d also likely be automatically allowing the installation of any software apps that might have been bundled with the main program. If one of those added apps is a hijacker, it’d also get installed on your machine if you use the Quick setup option. A good way of preventing this from happening while still getting the main program is going for the Custom/Advanced setup menu where you can choose to leave out the optional installs that you might not want to get on your PC. Do that every time you are about to install anything new and the chances of landing some pesky hijacker like Campaign Notifier would drastically go down.
