Malwarebytes has determined that BetterAds is adware. These adware applications display advertisements not originating from the sites you are browsing. This particular one was bundled with other software. The full version of Malwarebyte would have protected you against the adware. It would have warned you before it could install itself, giving you a chance to stop it before it became too late. The web protection module also blocks the download of the installer. The tool is available in the existing folder C:Windows. It adds the file unins000.dat.”]
