How to remove MediaDownloader from Mac?

What is MediaDownloader?

MediaDownloader is a rogue application that supposedly allows users to download media files and convert their formats. These claims often trick users into believing that MediaDownloader is a legitimate application. Be aware, however, that MediaDownloader is distributed using the "bundling" method and, thus, it often infiltrates systems without users' consent. Furthermore, this app delivers intrusive online advertisements and continually records data relating to Internet browsing activity. For these reasons, MediaDownloader is categorized as a potentially unwanted program (PUP) and adware.

MediaDownloader adware

Following infiltration, MediaDownloader employs a 'virtual layer' to generate pop-up, coupon, banner, and other similar ads. The virtual layer enables placement of third party graphical content on any site. Therefore, ads displayed by MediaDownloader often conceal underlying web content, thereby significantly diminishing the browsing experience. In addition, some redirect to malicious websites - even accidental clicks can result in high-risk adware or malware infections. In addition, MediaDownloader continually records IP addresses, websites visited, pages viewed, queries entered into search engines, and other similar information. This data might contain personal details that developers of MediaDownloader share with cooperating third parties (who often misuse private information to generate revenue). Thus, the presence of an information-tracking app on your system can lead to serious privacy issues or even identity theft. You are strongly advised to remove MediaDownloader from your computer immediately.

MediaDownloader shares many similarities with other adware-type applications such as WishApp, MyShopBot, and PowerSearchOnline. Note that all offer different features, however, they have identical behavior. Adware is designed only to generate revenue for the developers and regular users receive no significant value. PUPs such as MediaDownloader merely generate intrusive online advertisements (via the "Pay Per Click" advertising model) and collect various data (which is later shared with third parties to generate revenue).

How did MediaDownloader install on my computer?

MediaDownloader has an official download website, however, developers also distribute this PUP using a deceptive software marketing method called "bundling" - stealth installation of potentially unwanted programs with regular software. Research shows that many users rush the download/installation processes and skip most steps. Therefore, all bundled programs are hidden within the "Custom/Advanced" settings. By skipping this section, users expose their systems to risk of various infections.

How to avoid installation of potentially unwanted applications?

This situation can be prevented by taking two simple steps. PUPs are distributed using the bundling method and, therefore, never rush the download or installation processes. Closely analyze each step using the "Custom/Advanced" settings. Secondly, decline offers to download/install third party programs and opt-out of those already included.
