This page aims to help you remove CHELFNOTIFY “Virus”. These CHELFNOTIFY “Virus” removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

So, you’ve sought out this page because your browsing experience has literally turned into a living nightmare? We know exactly what you’re going through. The endless CHELFNOTIFY ads, popups, banners, the annoying new tabs and windows that keep opening on their own, plaguing your Chrome or Firefox browser. Yes, it’s all just too familiar and that is precisely why we’ve created this page. Our users have been complaining about the effects of a recent adware product called CHELFNOTIFY “Virus” and have been asking for ways to solve this problem that has made its way onto their machines. Read on and learn all there is to know about this software category and find out just what you need to do in order to safely remove it from your PC.

CHELFNOTIFY? What’s this about?

If you’re unfamiliar with the term ‘adware’, in short it comes from the words advertising software. This should probably shed more light on the weird and irritating things that have been going on within your browser lately. The point of any kind of adware is to display as many online adverts on your screen as possible, so as to ensure that you click on at least some of them. You might have even already ended up doing so, perhaps even by accident, since the intrusive box messages and links are literally everywhere and seem almost impossible to avoid. Well, there’s good reason for that, too. Adware developers, like those of CHELFNOTIFY, make money based on the amount of times people click on the showcased ads. This is a very popular and efficient business strategy called the Pay Per Click scheme and is what most products of this type are based on. However, where money’s involved there usually tends to be some extent of cheating.

In the case of adware, this kind of software is generally programmed to be able to spy on your browsing activity and analyze your search queries, browsing history, favorited pages and all other such data that would essentially help the developers determine what you are currently interested in. This way CHELFNOTIFY will be able to display ads that would ‘speak’ to you and would thus be more likely to get clicked. Though this may seem fairly logical and reasonable to some, many question the safety of such behavior on CHELFNOTIFY’s part and tend to be bothered by the fact that their privacy can be so easily invaded without their knowing consent. The fact that adware developers are known to sell the collected data to third parties also doesn’t help CHELFNOTIFY much and contributes to a rather shady reputation.

Risks and distribution

As if the above didn’t sound suspicious enough, there are also more drawbacks to having such programs on your computer than first meets the eye. For example, if you’ve ever heard of malvertisements (malicious + advertisements), there is the acute possibility of encountering those among the ads spread by adware. We’re not saying that CHELFNOTIFY or other programs of the kind are responsible for this – not at all. Much on the contrary, adware is not considered to be malicious or a virus or anything of the sort. Nevertheless, there are evil people out there, who aim to take advantage of unsuspecting internet users and infect them with dangerous viruses like Trojans and ransomware by injecting existing adverts with malware. If you happen to click on one such malvertisement, you are likely to immediately download the virus and suffer the consequences. Another fairly palpable effect programs like CHELFNOTIFY tend to have on computers is substantially slowing them down. Due to the amount of resources they call upon for the purpose of generating the insane amount of ads, they can start causing browser crashes and various system errors. If you’ve had CHELFNOTIFY long enough, chances are you’ve already started to experience this displeasure for yourself.

As far as distribution goes, it’s important to understand that in nine out of ten cases you probably authorized CHELFNOTIFY to integrate with your browser with your own hands. However, this process is usually not made known to the average user, because they tend to overlook some important aspects to installing new software and software developers are well aware of this. What we mean by this is the fact that when downloading some new piece of programming, be it some kind of freeware or shareware, people don’t bother reading the EULA or customizing the installation settings. This is important as failing to do so often results in the installation of a whole bunch of other programs that came bundled with the one the user was initially after. Therefore, always choose the advanced or custom settings in the setup wizard of a new program and you will be able to determine yourself what programs do get installed and which don’t. Now, below is the removal guide for CHELFNOTIFY. Read it carefully and follow the steps exactly as they are written and please let us know in the comments if you have any questions.
