ArchNanoor Extension: Understanding the Dangers and Defenses Against a Pervasive Browser Hijacker

What are the capabilities of ArchNanoor?

ArchNanoor is a browser hijacker, which basically is a type of software created to interfere with your web browsing settings. After installation, it changes your homepage or default search engine to one of its control, taking you away from your desired settings. In the case of this hijacker, it doesn’t stop just there. Not only does ArchNanoor alter the browser’s appearance, but it also sends ads straight to your search results or reroutes your searches entirely. The end of the story is that it aims to increase traffic to certain websites that are earning a revenue for the developers. In addition to the obvious interference in your online experience, ArchNanoor also keeps track of what websites you visit, what you inquire into the bar, and what you click on. Such information can also be used to create a profile for your interests, but sometimes this data is sold to third parties. This increases the potential dangers of your search information-use beyond direct targeted advertising.

In what ways can I get infected with the ArchNanoor virus?

Infections with the ArchNanoor virus most commonly happen after installing software from suspicious or unknown sources. Furthermore, such software is frequently included in the installation files of various free applications, or phony software updates. If you choose the ‘quick’ or ‘recommended’ installation settings, you may unknowingly agree to install the hijacker alongside the intended program. Following that, clicking on questionable links or advertisements could result in an automated downloading and installation of such undesirable software.

What are the warning signs of ArchNanoor?

There are a few obvious signs that you have installed ArchNanoor, Chromstera, Universal Browser or UniversalUpdater on your device. The homepage of your browser may change inexplicably, or a new toolbar may appear on your computer without your permission. You may be frequently redirected to ArchNanoor.com or any other website, and you will not be able to stop it. You may also see way too many windows popping up during your web browsing or different types of ads. For example, you may see ads or notifications about events on a website that does not contain ads or aggressive statements under normal circumstances.

Can clicking on ArchNanoor pop-ups be dangerous?

It is indeed very dangerous to click on these ArchNanoor pop-ups you see all over your screen. The websites you are re-directed to may end up loading your computer not only with more dangerous malware, but also try to steal from you some personal or identifiable information via phishing attacks. Even in seemingly safe situations, more aggressive adware can be installed on your computer if you happen to click on some misleading advertisement. Therefore, our general advice is to stay away from the ArchNanoor pop-ups and use the instructions on this page to remove the browser hijacker that is generating them.

Is ArchNanoor on Chrome making my browser slow?

With ArchNanoor on Chrome, browsing will also be very slow, aside from all the other types of ads and pop-ups disturbance. The bottom line is that the hijacker loads ads by exploiting the resources of your system and runs unnecessary processes in the background. As a result, this consumes a certain amount of performance power from the system, which makes the browser load the page for a long time and work sluggishly in general.

To finally not download ArchNanoor extension anymore, you need to uninstall all browser add-ons or toolbars that did not get your explicit permission. In addition, resetting browser settings will help eliminate the remaining changes automatically. You can also install an antivirus program.

Uninstall the ArchNanoor app and kill its processes

Note that sometimes an app, especially a rogue one, may ask you to install something else or keep some of its data (such as settings files) on your PC – never agree to that when trying to delete a potentially rogue software. You need to make sure that everything is removed from your PC to get rid of the malware.
