What is MapperState

MapperState is a Mac-oriented app that promotes advertising content along with new search settings. Usually, it is easy to spot if something suspicious has happened to your PC. Users infected with such software will see a number of ads, banners, coupons, proposals to enable push notifications, and many more unwanted changes that disrupt users’ experience. Such modifications affected across browsers make MapperState classified as adware and a browser hijacker. In general, browser hijackers change search settings so that entered queries are redirected through third-party pages to popular engines like Yahoo, Google, or Bing. By doing so, they become able to generate illegal traffic on live visits. Unfortunately, applications like MapperState are also capable of running data collection. This is possible because such software has permitted access to what you search and enter on the web. In other words, MapperState may also gather your personal data (e.g. passwords, IP addresses, geolocations, etc) to gain monetary benefits. This is why letting unwanted software work in your system may lead to privacy leaks as well as the distribution of other infections. In order to remove it from your computer completely, make sure to follow our guidelines below.

How MapperState infected your computer

Developers might employ various vectors to distribute programs like MapperState. However, most often cybercriminals take advantage of freeware repacks. These repacks often consist of pirated or cracked versions of licensed software. Most users search actively for such programs due to obvious reasons – to bypass paying for non-free programs. Although, because such repacks are totally free, developers have to earn money on advertising additional software. Sadly, additional content is usually forcefully imposed on users. This means that people end up facing new changes without their consent. Even if they agreed to install the advertised content intentionally, users are often unsatisfied about newly-assigned features. Whilst executing the installation of software, most users tend to limp through the steps presented during the setup. In other words, they skip important sections that include promotional offers. Thus, before hitting on the “Install” button, make sure to check the “Advanced” or “Custom” sections first. In some cases, users are offered to choose between “Recommended” and “Manual” types of installation. Always choose “Manual” to see what will be installed yourself.
