Nano Defender Malware

Nano Defender

Nano Defender is a browser-tracking malware app for Chrome, and other popular browsing programs for Windows that will take over your browser once installed. As soon as Nano Defender gets added to the targeted browser, it will begin spamming it with page-redirects, ads, and banners.

Few days ago Nano Defender was sold and the new developers are using it as a malware. Only the Chromium version seems to be affected (Chrome, Chromium, Edge, Opera)

The Nano Defender App

This type of undesirable software doesn’t try to hide its presence on the computer and so you will notice that it’s there as soon as you start the browser that is affected by it. At first, you may even think that your computer is under the attack of some dangerous virus such as a Trojan Horse. However, most browser-hijackers like Nano Defender are almost harmless in comparison to more malicious forms of malware such as Ransomware or the aforementioned Trojan Horses. This means that the changes Nano Defender has made in the default search engine, the homepage, or the toolbar of your main browser are unlikely to directly damage your system or do anything bad to the data you store on the computer. However, despite this, we cannot say that Nano Defender is a perfectly safe app or one that you should keep on your PC. Experts still regard browser hijackers like it as potentially unsafe and so it is best to uninstall Nano Defender as soon as you notice that it has been added to the browser.

Nano Defender on Chrome

The goal of Nano Defender is to track your browsing history on your Chrome, determine what your supposed interests are, and then show you ads and redirect you to sites that are relevant to those interests. Though at first this may sound useful for people who frequently do online shopping, it is inadvisable to trust any of the promotional content that gets shown inside your browser while there is a hijacker added to the latter.

This is because the ads may not always correctly represent what they are really linked to. Some of them may be misleading or outright fake and some may even redirect to hazardous sites when clicked upon. Therefore, if you want to keep your system out of trouble, it is best to keep away from the ads and the redirects that Nano Defender puts on your screen. Otherwise, you may be at risk of getting your machine infected with all kinds of malicious programs, including Viruses, Worms, Rootkits, Ransomware, and many others.

The Nano Defender Malware

Usually, junkware software like the Nano Defender malware doesn’t get distributed as a separate app. Once the user downloads the Nano Defender malware that carries the hijacker, he or she will usually not notice the added unwanted element and install everything that the installer offers.

Once the installation is finished, the hijacker would immediately get attached to the main browser in the system and begin flooding it with ads and messing with its settings. To stop this from happening in the future, you need to remember to always download new software only from sources you are sure you can trust and also to always check the Custom/Advanced setup settings in the installation wizards.
