Some web browsers (apparently most notoriously Microsoft Edge on Windows 10, but we also received a similar question from the Mac universe) claim that downloading and installing Stellarium may be dangerous because the publisher is unknown, or the installer has not been signed with some security certificate.

Apart from addictively stealing your time observing Stellarium's sky rendition, Stellarium is not dangerous and should not harm anything or anybody. The browser should offer some way to accept this warning and continue the download. If not, use another browser.

However, make sure to download Stellarium from stellarium.org, launchpad.net or sourceforge.net, and not some repackaged installation from freeware sites which may pack extra software or adware into their installers or "safe downloader apps" or may change browser settings (default browser, modify default search engine, ...) or other things you don't want and we cannot control.
