SimilarSites(.)com – Ways of Distribution

SimilarSites(.)com has a few ways in which it distributes. Third-party install setups are one of the primary ways that the unwanted program uses for distribution. Bundled programs and freeware can put the hijacker inside your computer. The freeware installers could have more components set to be installed, by default. Lots of settings could already be altered before you become aware of them and the hijacker’s existence. To prevent installations of unwanted software like that, can be achieved if you find Custom or Advanced settings, so to deselect components.


SimilarSites(.)com might use other ways of distribution to appear in your browser applications. One of the ways is with the help of a browser extension shown in the picture above.
