Remove NSBlock ads (Virus Removal Instructions)

NSBlock extension delivers ads and makes users visit questionable websites

NSBlock virus is a term that the computer security experts use to refer to a dubious computer security software designed and distributed by a German company called Domport GmbH & Co. This product is definitely not one worth trusting. Its official download site has been taken down, and the program now gets installed along with other freeware or shareware software ^[1]. At the time NSBlock.net domain existed, the creators of this software have introduced this software as an innovative and perspective computer security service capable of providing protection against a variety of contemporary viruses, Trojans ^[2], and other malware. Nevertheless, its ability to protect users’ devices against malware has always been questionable. This presumption can only be justified looking at the size of NSBlock executable which reaches only 2 MB. A file of such small size is unlikely to hold any advanced utilities which would be able to protect computers from potential malware attacks or exterminate malware that is already on the system. Of course, it is not all hopeless. The program may block you from entering a few suspicious pages, but by no means should you trust it to fend off more sophisticated parasites such as ransomware ^[3]. On the opposite, since this tool is monetized through pay-per-click ^[4] advertising, it may attract malware to your system through random and often unsafe NSBlock ads. We recommend staying away from any ads, pop-ups, banners and other links that show up while browsing the web until you remove NSBlock from your computer with the help of professional software, say Fortect Intego.

Since NSBlock is monetized through ads, the experts tend to call it an adware. There are two types of adware: legitimate and malicious, and, unfortunately, this particular application is leaning more towards the latter. Ads by NSBlock are unpredictable and may link to potentially dangerous web content including compromised tech support websites, phishing pages ^[5] and sites promoting fraudulent applications. The virus will make these redirects possible with the help of an invisible extension that it installs on the web browser. An icon of this extension is invisible, so it virtually impossible to tell it has been installed without going through the list of installed extensions. Needless to say, if you already find this component on your browser, you should disable it and proceed with NSBlock removal from the system. While the program is still on the computer, you should refrain from accessing online banking sites, social media platforms or email because you can never know what this invisible extension will be programmed to do next.

How did this extension find its way on my browser?

Adware developers are always after the users who are less experienced in computing and can be easily coaxed into installing NSBlock or any other advertising virus on their computers. The best results are typically achieved when malware developers put a deceptive marketing technique called bundling into action. This method allows tying two or more programs together and spreading them in a single software package. The problem is that less experienced users take such software packages for granted and install them on their computers without investigating them closely. This way, NSBlock can slip into the system undetected. Advanced settings can be used to prevent such installs. You should opt for these settings before you begin the installation and look for undesirable components in the proceeding steps. Opt out the selected options manually by unticking the pre-marked check boxes next to them.
