What is BlockNSurf?

Developed by Revizer Technologies Ltd, BlockNSurf (also can be found as Block and Surf, BlockAndSurf, Block-N-Surf) is a legitimate browser add-on, which is a clone of ShieldMe. This application may seem very attractive for parents whose kids have already started surfing the net. That’s because BlockNSurf supposedly has the database of ‘black list’ domains, can easily detect them and prevent children from visiting adult content websites. No matter how useful this service may seem to you, do not trust it blindly. Even though we cannot claim that it fails to fulfill promises, security experts have informed us that this app has specifically been designed for advertising purposes. That’s why in addition to protecting your child from visiting pornographic websites, it may initiate various unwanted activities. For example, it may generate lots of commercial advertisements (pop-up ads, pop-under ads, banner ads, in-text links, interstitials, etc.) labeled as ‘Ads by BlockNSurf’, ‘BlockNSurf Ads’, ‘Powered by Block and Surf’ and so on. Be aware that those advertisements may be filled with links to suspicious websites; therefore, it’s better not to click on any of them. Another negative feature of this app is related to the collection of data. It has been found that Block and Surf virus may use cookies for gathering your search terms, mostly visited websites, data entered in them, clicks, and similar non-personally identifiable information. However, it seems that it may also collect your email address, PC’s IP address, location and similar information, which can be considered to be personal. Therefore, by bringing in parental control in your child’s computer, you may unconsciously allow third parties to deliver suspicious content on it. That’s why we highly DO NOT recommend using it.

It’s very important to warn you that BlockNSurf redirects may happen on your computer out of nowhere. In this case, we highly recommend you to run a full system scan with Reimage (Windows OS) or Webroot SecureAnywhere AntiVirus (Mac OS X) and remove BlockAndSurf adware without any delay.

How can BlockNSurf hijack my computer?

BlockNSurf may enter your computer via software package. In other words, it may spread as an ‘optional download’ attached to various freewares; therefore, users who think that it’s enough to click the ‘next’ button for the installation of freewares, can easily end up with this adware on their PC’s without even realizing that. If you want to prevent such happening, you should start checking free programs properly. NEVER click the ‘next’ button without reading the terms. Make sure that double check every notification and if you are hundred percent sure that it does not contain ‘additional components’, you can hit the next button. However, in order to monitor the installation and gain the ability to opt out of ‘additional components’, you have to select Advanced or Custom installation option.

How to remove BlockNSurf virus?

Get rid of BlockNSurf virus either manually or automatically. If you prefer manual removal, we highly recommend checking the machine with a reliable anti-spyware after that in order to get rid of file leftovers.

You can remove BlockNSurf automatically with a help of one of these programs: Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus, Malwarebytes Anti Malware. We recommend these applications because they can easily delete potentially unwanted programs and viruses with all their files and registry entries that are related to them.
