TopMusicSearches is a Possibly Unwanted Program (PUP) with browser hijacker capabilities and the sole purpose of driving traffic for a fake search engine artificially and generating revenue by displaying third-party advertisements to the affected users. Some of the browser hijacker applications similar to TopMusicSearches try to lure users into installing them by boasting of having somewhat useful features. In reality, however, those functions are usually barely working and cannot produce satisfying results. The other popular tactic for the distribution of PUPs is called 'bundling,' and it consists of hiding the installation of the application inside the installation process of another more widely-used freeware program.
No matter how TopMusicSearchers found it way inside your computer, it will proceed to change certain browser settings immediately. The homepage, new page tab, and the default search engine will be set to open feed.topmusicsearches.com. As a result, every time that the browser is opened, it will generate traffic towards this fake search engine. The reason that infosec experts categorize such search engines as fake is that they are not capable of performing the most basic function one expects from them - delivering relevant search results. Instead, they redirect the users' search queries through an established search engine, in this case, search.yahoo.com.
It is recommended to remove applications such as TopMusicSearchers as soon as possible due to the potential security risks they may represent. Usually, they inject sponsored advertisements that could redirect the user to fraudulent third-party websites potentially, as well as collect various browsing data.
