Wave Browser is a legitimate Chromium-based browser, but if it appeared on your computer without you intentionally installing it, I would treat it as unwanted software. Malwarebytes classifies it as PUP.Optional.Wave, noting that it has been distributed through channels that can install it without clear user consent. (Malwarebytes)
It can sometimes arrive bundled with another free program or installer. The browser itself says it can run in the background and start with Windows, which can make its presence less obvious. (Wave Browser)
So, is it safe? If you deliberately installed it, it's not generally classified as traditional malware. If you don't recognize it, I'd uninstall it and run a full security scan. Wave provides official uninstall instructions for Windows and Mac. (Wave Browser Support)
