What is TheBlocker?

TheBlocker is one of those apps that promise to block suspicious websites, such as containing adult content, promoting aggression and so on. By using this apps, parents can protect their children from various issue. Thus, it’s not surprising that so many people have already installed TheBlocker add-on. Unfortunately, it’s just another member of adware and PUP (potentially unwanted program) family, which is similar to Surf-N-Block, Halt-It, Blockeru, BlockNSurf, and many others. In fact, this adware can hardly prevent accessing suspicious websites since it’s primary task is not to serve the users, but to promote third-party websites, collect clicks, and initiate other activities in order to generate income for its developers. Thus, once installed, BlockNSurf virus may take over each of your web browser, including Google Chrome, Mozilla Firefox, and Internet Explorer. Right after that, you may start receiving tons of pop-up ads, pop-under ads, banner ads, in-text links and other types of commercial messages. However, it’s very important to stay away from them even though that it may be difficult to do that. ‘Ads by BlockNSurf’ tend to show up unexpectedly; therefore, you may easily click on the accidentally. Be aware that those ads are prepared by third parties who seek to promote their websites, services, products or even other suspicious software. Thus, you can never known to what websites TheBlocker ads can redirect you. In addition, TheBlocker may also install cookies on each of your web browsers and track your activities on the Internet. It may collect your search terms, websites visited, data entered, clicks, IP address, email address, PC’s location and so on. Finally, it may also slow down your computer, increase security vulnerabilities and cause other suspicious activities. Thus, in order to keep your computer safe, we recommend removing it with the help of a reputable anti-spyware, such as Reimage (Windows OS) or Webroot SecureAnywhere AntiVirus (Mac OS X).

How can TheBlocker hijack my computer?

TheBlocker may infiltrate your computer by means of other freewares and sharewares. ‘Bundling’ is a popular software marketing method, which enable third parties to spread add-ons, plug-ins, toolbars, and extensions without asking for users’ permission directly. Therefore, users who think that it’s enough to click the ‘next’ button all the time for accomplishing the installation, risk ending up with various PUPs on the PCs. 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.
