What is Jstag.js/Uk-ads.openx.net “Virus”?

If you are reading this article, you may have experienced problems with getting rid of unwanted, browser redirects to suspiciously looking websites, aggressively appearing advertisements in the form of banners, colourful links, pop-ups or pop-unders on your browser. No matter whether it is Chrome, Explorer, Firefox or other kind of a web browser. The news is you may have encountered Jstag.js/Uk-ads.openx.net. It is classified as an Adware. The following information will give you an idea of what you are dealing with and some useful advice about how to avoid it and remove it from you machine.

Adware is software that displays advertisements on your computer or within the program itself. You are most likely to come across Adware when you download free software from websites that work with torrents; or by clicking on an advertising link on an already infected webpage. Just the fact that a program is referred to as Adware, though, does not make it in any way malicious in nature. Many people are mislead that Jstag.js/Uk-ads.openx.net is a virus, though it may have some of the same functions it doesn’t fall into the virus category.

In fact, there are many legitimate programs, including games, that may display pop-up, pop-under or banner ads on your computer screen. Most of these programs show such ads to generate further revenue for the developers or to promote other products that they may sell. What we can point out as an advantage of a legitimate Adware program is that you can sometimes download the software bundle for free. Instead of charging you for the given program, the developers may integrate a script in it to display advertisements within to cover the costs of development. That is actually how they are able to make the profit they could normally get from selling their now free software. Such legitimate versions of Adware programs will contain an End-User License Agreement that will explicitly state if and how advertisements will be shown.

When you uninstall Adware, the program may be completely removed and may stop displaying advertisement pop-ups, pop-unders or banners on your computer screen. On the other hand, there may be Adware programs that are considered Potentially Unwanted Programs (PUP). Such software products might show ads without your permission. Also, you may not be aware of the origin of your annoyance. Such Adware versions may be designed to make it hard for you to remove them in order to continue generating profit through their advertisements. When you install the main software that is bundled with them, the Adware programs will be installed as well and will start showing numerous kinds of advertisements on your computer screen.

However, it is necessary to focus on the fact that Adware is nothing like a virus or malware. It has gained such a bad reputation because of the shady methods of distribution the developers use when it comes to Adware. The fact that Adware comes in bundles with other software and the user may not be aware of its existence and installation is what makes its image so controversial.
