Why Was UltraViewer Installed on My New Laptop Without My Permission?

UltraViewer generally doesn’t install itself. Possible explanations include manufacturer or retailer-installed software, bundled software during setup, or someone else having access to the laptop. Since you’ve uninstalled it and the security scans were clean, that’s reassuring. Check Settings > Apps and Task Scheduler for any remaining UltraViewer entries or scheduled tasks.

If the laptop was sold as brand new, check where it was purchased and whether a store performed setup or installed extra software. Retailers sometimes add support tools or other bundled programs. You can also review the installed-app dates and startup programs to see when it appeared.

For maximum peace of mind, back up your personal files and perform a clean Windows installation using official installation media. That removes questionable bundled software, but it may be unnecessary if the laptop was genuinely new, UltraViewer is gone, and multiple reputable scans are clean. Also consider removing McAfee if you don’t want it; Windows Security is generally sufficient for most users.
