This page aims to help you remove the Snarer.dll “Virus”. Our removal instructions work for Chrome, Firefox and Internet Explorer.

Adware programs can be a real pain in the neck and the worst part is – they always tend to show up when you least expect them. The same is true for a particular representative of this software category – Snarer.dll “Virus”. We’re guessing that you’re on this page due to this very same program and you probably came to discover it on your PC thanks to the numerous popups, banners, box messages and various other ads that have flooded your Chrome, Firefox, Edge, Opera or other favorite browser. Well, that is after all the primary objective of any adware programs, but we will elaborate more on that further down in this article. And once you’re finished reading it (which we highly recommend you do, by the way), you can then head over to our removal guide, which will provide you with all the necessary steps you will need to take, if you intend to remove Snarer.dll “Virus” from your computer and rid yourself of its annoying ads.

What is the point of Snarer.dll “Virus”? Is it dangerous?

As we already pointed out, programs like the one you are currently faced with are all about generating various online ads within your browser and exposing you to those ads. That is how they ensure the promotion of various products and services to the benefit of the vendors and providers of those products and services. However, there’s more to it than just that. The developers of this kind of software need to benefit in some way from it, don’t they? And they do. In fact, most of the time it is in accordance with remuneration systems like the Pay Per Click scheme, which ensures that the developers of adware and other similar programs can earn revenue based on the amount of clicks the said online ads receive from users such as yourself.

However, there tend to be issues with this way of doing business and one of them is the fact that software like Snarer.dll “Virus” can often be programmed to monitor your browsing history. Moreover, it may actually then extract certain information from your browsing history and use it to optimize its online advertising campaign. For instance, a common thing that such programs may take into consideration is your latest search requests and the websites you tend to spend the most time on. Alternatively, or even in combination with the above, they may look into the kind of content you like and share on social media, so as to gain a better perspective of the kind of products and services will be more likely to interest you. Once the adware has gathered a substantial enough amount of data, it can then use it to tailor the ads it displays to your personal taste. That will, in turn, increase its chances of gaining more clicks from you.

But the issue remains and it’s the matter of privacy violation, which hardly anyone would like to overlook. Aside from being pried on in this fashion, the data gathered can later easily be sold to various third parties, including other marketing companies, which most likely won’t hesitate to target you – also not something to look forward to. With all that in mind, it would certainly make more sense to remove Snarer.dll “Virus” now, even if you were able to put up with the irritation that the constant popups and banners may cause. But in case more convincing is required, there is yet another aspect, in fact, a more serious one that ought to be taken into consideration and it involves the potential of getting infected by something far more dangerous than any adware program can be.

We are referring to the risk of bumping into actual computer viruses like Trojans and ransomware. Though not itself a virus, a program of the same rank as Snarer.dll “Virus” could expose you to malware and other harmful threats by means of those very ads that we’ve been talking about throughout this entire article. Hackers commonly use online ads and inject them with the malicious scripts of their viruses like the ones we mentioned so as to ensure that they get distributed. Users will then click on those ads, thinking they’re legitimate or even just by accident and end up getting infected by some very dangerous program. In this regard we think it important to warn users against interacting with any online ads, as you can never know whether you’re looking at a genuine ad or a compromised one.
