HDMusicStreamSearch is an extension that can be download for Google Chrome, Mozilla Firefox, MS Edge, or another web browser. While the app can be obtained from relatively secure sources such as the Chrome web store, most users find it on their systems seemingly out of nowhere. This happens due to deceptive distribution techniques that the developers use – software bundling or misleading ads.
Since the app attaches itself to a web browser and changes its settings abruptly (for example, the homepage and new tab address is set to portal.hdmusicstreamsearch.com or feed.hdmusicstreamsearch.com), some might call it the HDMusicStreamSearch virus. While technically this term is not correct, there are plenty of reasons why this extension should not be kept installed on the system – it tracks users’ browsing activities, changes the default search provider, and inserts unwanted ads.
