WHAT IS MICROCHALLENGER?

MicroChallenger is another program presenting itself as a shopping assistant that will help you with your burden of finding the best offers online. However, MicroChallenger follows the path of various similar applications that take the easiest way and pretend to display ads for your own good while in reality they promote affiliated websites that might redirect you to some really suspicious or even dangerous locations as there is no security system that would filter safe or unsafe websites that are shown to you. Clients pay and MicroChallenger displays their ads no matter what they promote. Therefore, it is not surprising that MicroChallenger is classified as a potentially unwanted program (PUP) and adware. If you have not encountered the workings of adware-type programs on your computer before, you may be surprised by the incredulous amounts of ads you will see. There will be sponsored ads, deals, offers, banners, pop-ups, plug-ins, add-ons, underlined words in texts flashing on your screen and popping up in new windows and tabs. Therefore, while you may be reluctant to click these ads, you can still do it accidentally. What is more, it has been reported that MicroChallenger can change your default browser homepage and configure your browser settings. If this is not enough, you should know that MicroChallenger installs cookies on your browser and tracks your browsing-related information in order to present you with more appealing ads. Therefore, MicroChallenger is not a program you should have on your computer if you want to enjoy fast performance of your system, which might be interrupted, if you keep MicroChallenger adware, since it may make certain modifications in order to be launched once your computer is rebooted. What is more, it may connect to the Internet without your permission using unsafe channels. Therefore, there are virtually no benefits of using such programs while the consequences might be rather serious. For this reason, we would highly advice you to get rid of MicroChallenger adware once and for all with some reputable anti-spyware tool like Reimage.
