Code that isn't in itself unwanted software, but downloads other mobile unwanted software (MUwS).
Code may be a hostile downloader if:
- There is reason to believe it was created to spread MUwS and it has downloaded MUwS or contains code that could download and install apps; or
- At least 5% of apps downloaded by it are MUwS with a minimum threshold of 500 observed app downloads (25 observed MUwS downloads).
Major browsers and file-sharing apps aren't considered hostile downloaders as long as:
- They don't drive downloads without user interaction; and
- All software downloads are initiated by consenting users.
