Where does GrandBurst come from?

Currently, GrandBurst is compatible only with Google Chrome, but it is not available on Chrome Web Store yet, or the extension might have been already removed from this site. Nonetheless, its creators could spread it through other channels, for example, bundled software installers. If you download freeware setup files from unreliable web pages, you might receive an installer with suggestions of such unreliable software as this extension. Therefore, it could be safer to avoid file-sharing web pages in the future, or at least review terms on the setup wizard more carefully, so you would not overlook any unwanted suggestions.

How does GrandBurst work?

During the installation process, GrandBurst should create a couple of folders titled as mllhnlpgjighmgnmcjabealfmihkmjhi in the %LOCALAPPDATA%\Google\Chrome\User Data\Default\Extensions and %USERPROFILE%\Local Settings\Application Data\Google\Chrome\User Data\Default directories. In case there are several Google Chrome profiles on the computer the adware should create even more folders and data. To replace user’s default browser setting the extension could modify specific files called Preferences and Secure Preferences.

After it settles in, the Google Chrome browser might start loading when it is launched. The website provides a search box and some icons with links to other pages, e.g.,,, and so on. Also, you can set a custom background picture, place a clock or make it show the date. Thus, the first impression of the site might make it look like a fun and useful tool to search the Internet. Unfortunately, the idea might be ruined once you start using the provided search engine. As our researchers at indicate, the results could include unreliable third-party ads. For example, they could redirect you to web pages distributing similar threats, sites trying to steal your private data, spread malicious applications, and so on.
