PUA:Win32/MediaArena is a detection of a potentially unwanted program (PUP) that may negatively impact the computer when installed. Typically, programs detected as PUA:Win32/MediaArena are applications that are embedded with legitimate software. Although the host program itself is valid, all bundled products from different developers may lead to behavior errors or conflicts. Thus, in order to protect Windows users from this unwanted installation of third-party applications, Microsoft Defender alerts users about malicious installation software and identifies it as PUA:Win32/MediaArena.
PUA:Win32/MediaArena normally arrives on the computer uninvited. It is usually embedded in malicious freeware or shareware. Once active on the computer, this virus can perform different actions that could annoy the user. Most of the time, it displays pop-up ads and redirects when it senses that the web user is browsing the internet.
How does it infect the computer?
PUA:Win32/MediaArena is distributed through online promotions, including ads and email campaigns. Most of the time, it is bundled with legitimate applications such as the app, file-downloader, or Internet speed booster. However, there are occasions when other unknown software that come with it may not have the same reputation and could cause adverse effects on the computer. The purpose of creating these bundled applications is to promote them by integrating software into the host and running a simultaneous installation. In essence, programs referred to as PUA:Win32/MediaArena use a sneaky approach to entering the computer.
Users have the option of not installing a file identified as PUA:Win32/MediaArena. However, some users may accidentally install the bundled applications when running the configuration while ignoring the options provided during the installation.
How does this malware operate?
The primary goal of PUA:Win32/MediaArena is simply to install the extra software. Of course, developers are involved in a pay-per-install campaign, and they receive revenue from these software providers by incorporating the installation files into the main application. As noted, PUA:Win32/MediaArena does not apply to the mandatory installation of a third-party application, as it provides users with removal options.
