Does the appearance of plenty of ads in the form of popups, banners and others while you are browsing the web sound familiar to you? Does that happen no matter what browser app you load, for example, Chrome,Firefox or Explorer? Maybe you have no idea what has been going on with your computer. Luckily, we have the correct answers to your questions. The piece of software that may have been currently annoying you is FileRepMetagen and falls into the Adware category. More info about this kind of programs in general and FileRepMetagen in particular has been shared in the paragraphs below.

FileRepMetagen Malware

FileRepMetagen is a potentially unwanted program also known as PUP.That means we don’t need programs such as FileRepMetagen on our computer, but they still install on our computer without our permission.

Almost all programs able to show a really big number of different ads can be identified as representatives of this software family. In fact, Adware’s real purpose is simply to display pop-ups, banners and tabs and in this way – promote different products and services.

The really calming news is that this usually irritating type of software is unable to put your PC in any danger. To be precise, no version of Adware has virus-like traits. However, most Adware programs may be capable of affecting all your browsers – Explorer, Firefox, and Chrome also. They could be able to review your browsing activities and conduct the production of ads in correspondence with your supposed interests and searches. Some experts in this field and some of the affected users as well have seen such a trait as annoying enough to identify Adware as potentially unwanted software as a whole. Nevertheless, these programs are basically harmless and what’s more – legal.

What are the basic differences between FileRepMetagen and any form of a popular virus?

In this passage we will explain the main difference between the programs built on Adware and the ones that are regarded as really malicious:

  • If you happen to experience an infection with FileRepMetagen, you may get annoyed by a considerable number of advertisements based on your interests, and your PC may even become slower since such the mass generation of online ads is normally resource-consuming. Still, such processes are not really dangerous.
  • If you catch an infection with either a version of Ransomware or a Trojan, you will most likely experience the hacking of your system, the thorough scanning of your disks, some encryption of your data, probably some ransom alerts and warnings, as well as possibly even the theft of account details or even spying on all your activities while online or on your PC.

So we can say FileRepMetagen is legal and not dangerous, right?

Yes, FileRepMetagen is a legitimate marketing tool, especially designed to promote certain goods and services online by showing the victim users as many ads as possible. Programmers and manufacturers work together towards ensuring the efficient advertising. Normally, the developers get sufficient payments directly related to the number of the opened or clicked-on ads. The manufacturers, on the other hand, could gain huge profits from all the people who purchase their products. This cooperation is beneficial for both sides, just not for the users exposed to any form of Adware, because of the possible annoyance that may come along with it.

But how can an infection with FileRepMetagen occur in the first place?

One more aspect of the behavior of Adware in general that may raise some concerns among the majority of users and contribute even more to this software’s noxious reputation is the ways in which there programs get around. Typically, distribution could take place in quite a shady way. Firstly, let us mention the probable sources of Adware: they are mainly the popular program bundles. Such sets of applications, programs and games could be downloaded from anywhere on the Internet – in most of the cases – for free. This may seem unclear as you might simply be interested in trying a specific program from this exact mix. However, you may be installing all of a bundle’s components if you are not aware of the way to safely incorporate it in your system. This is the most important part of the prevention of Adware – to install software properly. Such a wise installation process may only be achieved if you choose the Custom or Advanced wizard feature.

All of the other options – the Default or the Automatic ones are in fact bad for your PC’s safety and health. Thus, you need to avoid using them. Only the Custom way of installing any software can give you the opportunity to exclude all unwanted programs from the bundle from getting installed, and the potential Adware products inside it as well. For the safe removal of FileRepMetagen we have created a Removal Guide with detailed instructions – you can access it for free below. Hopefully, it will get the problem solved in your case.
