How Does MicroChallenger Work?

MicroChallenger enters your PC without your knowledge but with your permission. This is possible when you download a free program with which MicroChallenger is bundled. Once the freeware is installed on your computer, MicroChallenger enters it as well. In order to stop PUPs from entering your system when downloading freeware, you must disallow all features you are not familiar with and opt for custom installation instead.

The websites you normally visit may be covered with banners, pop-ups and in-text hyperlinks as well. Note that clicking any of these ads may redirect you to unwanted and possibly corrupted webpages that may further infect your system.

In fact, that is how MicroChallenger works: It tricks you into clicking ads sponsored by third parties, and this way the ad-supported program generates traffic to the third parties. However, MicroChallenger is not responsible for the content of these third-party websites – it only redirects you to its sponsors.

In addition, MicroChallenger may also monitor your browsing routine, record that information along with some personal data and share it with the sponsoring third parties.

The adware program, therefore, may not be malicious by nature, but it may put your system and sensitive data at risk.
