Earthapp.net and Earth3d.net are closely related browser-redirect domains tied to Earth/Earth 3D themed hijacker pages and extensions. If your browser briefly opens either domain during search, new-tab, or startup activity, remove the extension that controls the redirect, restore your search and new-tab settings, and scan for adware if the redirect returns.
Gridinsoft’s Website Reputation Checker currently rates Earthapp.net at 9/100 and Earth3d.net at 11/100, with both pages warning about blacklisted or low-trust signals. That does not mean every device has a severe infection, but it is enough reason to stop the redirect and avoid entering personal or payment information on pages reached through it.
What are Earthapp.net and Earth3d.net?
Earthapp.net and Earth3d.net are promoted redirect domains that use an Earth or 3D Earth theme to look like a browser tool, search page, wallpaper feature, or new-tab enhancement. In practice, this type of page often behaves like a browser hijacker: it changes search flow, new-tab behavior, or startup pages so traffic passes through a promoted domain.
The exact extension name can vary, so focus on the domain and symptoms rather than only the visible branding. If the address bar shows Earthapp.net or Earth3d.net before another search page loads, treat it as a redirect chain that needs cleanup.
Common symptoms
- Searches or new tabs briefly pass through
earthapp.netorearth3d.net. - An Earth, Earth 3D, map, wallpaper, search, or new-tab extension appears unexpectedly.

Scan if the redirect keeps returning
If Earthapp.net or Earth3d.net returns after extension removal and browser reset, check Windows for the persistence source. Potentially unwanted apps can reinstall browser extensions, change shortcuts, add startup entries, or launch browser tabs through scheduled tasks.
- Uninstall recently added apps that came with the extension.
- Check browser shortcuts for a URL added after the executable path.
- Review startup apps and scheduled tasks for unknown entries.
- Scan the device if multiple browsers are affected or the extension reinstalls itself.
Gridinsoft Anti-Malware can check for adware, browser hijackers, unwanted startup entries, scheduled tasks, and bundled programs that keep redirecting the browser after manual cleanup.
What not to click
Do not install a second extension from the redirect page, click fake update prompts, or enter passwords, payment details, or phone numbers on pages opened through Earthapp.net or Earth3d.net. If a page claims that a browser tool is required to continue, close the tab and remove the extension from the browser’s settings instead.
Prevention
- Install browser extensions only from trusted publishers.
- Be careful with add-ons that ask to control search, homepage, new tab, or all websites.
- Remove extensions you no longer use.
- Review browser sync after cleanup so unwanted extensions do not return from another device.
- Check unfamiliar domains with a reputation scanner before trusting them.
FAQ
Are Earthapp.net and Earth3d.net viruses?
They are best treated as low-trust browser redirect domains tied to adware or hijacker behavior. The redirect alone is not proof of a destructive virus, but it is a strong reason to clean browser extensions and settings.
Why are there two similar domains?
Hijacker campaigns often use related domains and branding variations. In this case, Earthapp.net and Earth3d.net fit the same cleanup lane, so one cluster guide is more useful than two thin pages.
Should I reset Chrome or Edge?
Reset the browser if removing the extension and fixing search/new-tab settings does not stop the redirect. If the redirect still returns, scan Windows for adware or persistence.
Can browser sync bring the redirect back?
Yes. If another device or profile still has the unwanted extension, browser sync can restore it. Remove the extension from all synced browsers.
