What is Surf-N-Block?

Surf-N-Block (also known as BlockNSurf or BlockAndSurf) is an adware or a potentially unwanted program (PUP), which can infiltrate target computers in a suspicious way and may initiate various activities for marketing purposes. The app is supposed to block suspicious websites, such as filled with adult content. However, it has been found that the program is capable not only blocking suspicious websites, but may also deliver untrustworthy content during your browsing, may spy on you and affect your PC’s performance in a negative way. It is supported by advertising or, in other words, it’s a typical adware. It means that it can deliver sponsored advertisements on each of your web browsers, including Google Chrome, Mozilla Firefox, and Internet Explorer. Security experts highly do not recommend clicking on any of the ‘Ads by Surf-N-Block’, ‘ Surf-N-Block Ads’ or ‘Surf-N-Block Deals’ because they may be linked to really suspicious websites. Unfortunately, it may be difficult not to get in touch with those ads because they tend to appear unpredictably in such annoying forms as pop-up, pop-under, banner ads or in-text links. Be very careful as clicking on any of them, Surf-N-Block redirects may occur and you may even end up with another PUP, virus or malware on your computer.

By the way, you may be tempted to click on Surf-N-Block ads as they are usually personalized according to user’s preferences. To be more precise, this adware may install cookies on each web browser (Google Chrome, Mozilla Firefox, Internet Explorer, Safari) and collect information related to user’s browsing habits, for example, search terms, websites visited, data entered, clicks, IP address, PC’s geographical location, email address, etc. Gathered information may be shared with other third parties; so, it’s better not to disclose it because third parties may misuse it for really suspicious purposes. All in all, it seems that instead of blocking suspicious websites, Surf-N-Block virus may deliver suspicious content to you itself. Thus, in order to prevent various computer-related issues, you are strongly advised to remove this adware from the system right away. For that, we recommend using Reimage (Windows OS) or Webroot SecureAnywhere AntiVirus (Mac OS X).

How can Surf-N-Block hijack my computer?

Be aware that Surf-N-Block does not pose any risk until you stay away from its ads. Nevertheless, it may continuously spy on you, affect your PC’s performance, increase security vulnerabilities, and so on. Thus, it’s better to stay away from this program at all. In order to do that, you have to bear in mind that this add-on may land on your computer without being noticed alongside other freewares. It may be attached to various download managers, PDF creators, media players, etc. and disclosed in a very misleading manner. Thus, for getting the ability to detect and opt out of it, you have to spare some time on freeware’s installation. Always opt for Advanced or Custom installation and go through the process step-by-step. If you spot an offer to install browser add-on, plug-in, toolbar or extension such as Surf-N-Block, make sure that you unmark ticks that are marked alongside it.
