Why should you not take the Authentication Required notifications for granted?

Authentication Required virus is a perfect example of the tech-support scam viruses that have been reigning the Internet over the last year. These viruses are deceptive, tricky to remove and can also be highly dangerous. Though the majority of the tech-support viruses today use lock screen and double as ransomware, there are also some less dangerous variants of these infections which are closer to an annoying adware rather than dangerous data-stealing parasites. This is exactly what the Authentication Required malware is about. This virus will not lock your computer, and you will not suffer from any data loss either, but it will surely ruin your browsing experience. Besides the fake Authentication Required notifications you may also find your browser occupied by other annoying ads, banners, video advertisements, some pages may open to random pop-ups asking to fill some survey or register for an online game. Do not be deceived because all of this content is just a bait designed to extract some relevant information, redirect you to the sponsored websites or sell you predetermined goods/services. We do not know what specific adware is responsible for generating these ads, but to remove Authentication Required notifications from your browser, you will have to decontaminate this PUP first. To do that properly, you should scan your PC with your current antivirus software or obtain a newer and a more modern one, for instance Reimage.

Example of the Authentication Required ads

Authentication Required ads are rather easy to recognize. Usually, they warn the users about the supposed corruption of the Windows activation key and urge them to contact “Help Desk” to receive a new one. In reality, the computer and its operating system are completely fine and the messages notifying about such errors should cease to show up when the browser is not in use. This only proves that you are dealing with an Authentication Required hijack and suggest that you should scan your computer immediately. Do not contact any tech-support numbers indicated in such ads and do not purchase any contracts or software if you are not sure about their legitimacy. Most importantly, remove Authentication Required from your computer and make sure your system is protected from the potential dangers the unsafe adware redirects may trigger.

How can these notification start appearing on my browser?

If you know the basic principles by which the potentially unwanted programs are distributed, you should not find it difficult to understand how the Authentication Required adware have found its way on your computer. It was simply attached to other software and installed along with it. Unlike what most users think, such installation does not necessarily have to be completely overt. All it takes is for you to agree to install the package with which the malware initially came, and the rest will be done automatically. To have some more control over this process, choose “Advanced” or “Custom” installation and opt out the components you do not wish to see on your computer.

What are the Authentication Required removal options?

If the Authentication Required virus got you completely lost, do not worry, we know a way out. In fact, there are two ways. If you are interested in quick and guaranteed results, scan your PC with an anti-malware utility. The automatic system scan will clear your system from the potential security and health hazards and will carry out the Authentication Required removal in just a couple of minutes. Manual elimination, on the other hand, may take a little longer.
