Adware is not a necessary new term, especially in the online world. It describes an ad-supported software that was made to take advantage of browser’s connection to the internet to serve as many advertisements as it can in the essence of generating online profit. One example of adware that exploits internet browser programs like Safari and Google Chrome is named HandlerSearch.
How does HandlerSearch infect the Mac computer?
Mac user may come into contact with HandlerSearch after downloading and installing maliciously modified freeware, shareware, or any third-party application where it is incorporated. This tactic aims to hide the installation of HandlerSearch during the setup process of the free software. It gains access with minimal to no effort using the carrier, while victims will surely find too much difficulty with the removal of this unwanted program.
Actually, Mac user can evade this intrusive penetrating ploy if they only take the extra steps in running the setup through Custom (Advanced) mode. Via this course, Mac users may be able to view the exact contents of the freeware and opt-out for the installation of HandlerSearch app or any inclusions that are not necessary because, aside from this adware, CentralDepart and DynamicPositive may also be part of the bundle. Sadly, nearly all computer users, both PC and Mac clients, are still attached to the traditional way of running the Default setup process, which is able to install all the extra inclusions.
Effects of installing HandlerSearch app
Right after Mac user accidentally mount HandlerSearch app on the browser program, it may never take a minute before witnessing various issues. The affected internet software may pop-up an alert stating that HandlerSearch app is trying to access confidential data stored on the browser. In addition, pop-up ads and redirects may start showing up on places where it block web user’s view. These overlaying ads are intentional in influencing Mac user to visit sites that are often involved in the marketing of bogus security applications, fake software updates, or unreliable optimization tools.
The worst part may come sooner if Mac users continue to ignore the presence of HandlerSearch app. By redirecting browser pages to drive-by-download sites and pages, malware infection is bound to happen, and it is executed without their approval. Therefore, avoiding this infection is just a matter of removing HandlerSearch app as early as possible.
