Malwarebytes gets tougher on PUPs
PUP.Optional.GoMusix is the detection for a Chrome extension called MusicBoxSearch that hijacks the new tab and search results. This PUP is a hijacker and part of a family of similar hijackers sometimes referred to as BLPSearch, because of the name of their default search keyword, but in this extensions case the keyword is MusicBox.
Users could notice their default search engine has changed to Yahoo and the presence of a new extension, visible in the Chrome menu-bar and the list of extensions.

the PUP takes over the Search engine settings oof Chrome
There are basically two ways to get this Chrome extension. One method is from the webstore. The other is by installing the extensions from sites pointed to by ad-rotators. These sites usually also offer a Firefox add-on if you happen to visit them using the Firefox browser.

Users that had their browsers hijacked should have a look at our Restore Browser page to see if additional measures are needed.
Malwarebytes blocks the websites that push this extension and the domains that belong to the hijackers.
