Enter a Product Key “Virus” – a malicious virus or a harmless bloatware?

Many users have reported having problem with the appearance of various intrusive pop-up ads once they open their browser. Some people even begin to panic, thinking that their PC has been infected by some kind of a malicious and harmful program (like a Trojan or a Ransomware). However, if the only symptoms that something is not quite right are the annoying browser ads, then it is probably not a virus or some other dangerous software. Obstructive browser ads are typical feat of a certain type of program called adware. These are very widely spread throughout the internet. Still, as annoying and frustrating as they might be, adware are generally harmless for your system. Referring to them as viruses is incorrect. Virus programs illegal and are meant to harm your computer, steal data or money from you or spy on you. Adware applications don’t do that and most of them are perfectly, at least according to the law. This, however, does not make them wanted by most users, in any way. The reason for that is because they are just way too annoying and intrusive to have around. Besides they have little to no use for most people. A general term for such programs is Bloatware. Adware apps fall under this category. Enter a Product Key is one of the latest adware programs. A typical trait for this kind of software is that separate versions hardly ever have any substantial differences between each other. Therefore, what applies to one of them will, for the most part, apply to all the rest.

But what does Enter a Product Key do?

Obviously it generates ads. This is its main purpose. The ads usually have nothing useful for you. However, from them Enter a Product Key’s developers gain revenue via the pay-per-click method. This means that the more you click on the intrusive banners, box messages and pop-ups, the more money the person who’s created the annoying program will receive. There’s virtually no reason for you to do that. In fact, there are several reasons why you should not. You see, the majority of ads are not fake or dangerous. However, every now and then there’s some chance that you land on a add that may redirect you to an illegal or even malicious page that is infested with viruses. Furthermore, interacting with some of the pop-ups might even start downloading more unwanted content on your machine. This is rare and as we already said, most of the ads are okay. Still, even the legit ones will hardly have any use for you. That is why we advise our readers to simply avoid the obstructive pop-ups and quickly find a way to get rid of the unwanted software. For this we’ve provided you with a guide on how to uninstall and remove Enter a Product Key, just below this article.

How did I get Enter a Product Key on my PC?

 It should be clear by now that no one in their right mind would attempt to install such a program on their machine. That’s why adware’s developers have had to come up with other ways of distributing their products.

  • A very common method, that we’ve all heard about, are the spam e-mails. This one, however, is not overly effective. Spam messages usually go to the spam folder and no one really opens letters from that folder, do they? Still, you should always be careful even when checking your regular inbox. Sometimes a unwanted e-mail may get there. Therefore, make sure to always look at the title of the letter and the name of the sender first, before opening the message.
  • Another widely-spread method for Enter a Product Key distribution is via torrent files. It’s just so easy for everyone to upload whatever they want to a torrent or file-sharing site, that you can never be 100% sure that the downloadable content in such sites is legit and safe. We know that this will probably not be enough for you to stop using them. Therefore, at least try to pick torrents that look trustworthy, have good ratings and high number of downloads.
  • Probably the most effective way for Enter a Product Key distribution is the file-bundling. For the most part, this is a perfectly legal method and if an adware gets into your system via file-bundling, it is usually your not paying attention to the installation menu. When the intrusive software is bundled with another program, it gets installed along that other program. However, you can easily prevent this from happening. All you have to do is opt for the advanced/custom settings in the installation menu so that you are able to see all added installs. Once you have the list of add-ons in front of you, simply uncheck everything that you may not want getting on your machine once the installation of the main program has finished. Do that with every new program you install, because most of them (especially free or cheap ones) have something added, that you probably don’t need (or want). Just keep in mind that it is much easier to prevent the installation of Enter a Product Key that it is to have it uninstalled and removed aftwarwards.

    • Thanks for the quick reply!

      When you say they are “legit”, what do you mean? Are they third-parties, or something else? Not really concerned, just interested.

      • Hi again Owen,
        if you open your hosts.txt file just before the IPS you can see:
        # localhost name resolution is handled within DNS itself.
        # localhost
        # ::1 localhost is the loopback Internet protocol address also referred to as the “localhost.” The address is used to establish an IP connection to the same machine or computer being used by the end-user. The same convention is defined for computer’s that support IPv6 addressing using the connotation of ::1. Establishing a connection using the address is the most common practice. The loopback construct gives a computer or device capable of networking the capability to validate or establish the IP stack on the machine.
