MinerSearch redirect is the symptom to fix when Firefox, Chrome, or Edge suddenly lists MINERSEARCH as a search engine and sends address-bar searches to Bing, Yahoo, or another provider you did not choose. Remove the suspicious extension first, restore the default search engine and search shortcuts, then check browser policies and Windows startup items if the setting comes back after restart.
Do not confuse every mention of MinerSearch with a browser hijacker. There is also an open-source Windows utility named MinerSearch that is described as a tool for finding and removing silent miners [1]. This guide is about the unwanted browser-search setting or redirect behavior, not an accusation against the legitimate GitHub project.
If your browser is also opening random tabs or push-notification pages, use this page together with the PUA and browser hijacker removal guide and the multiple-tabs troubleshooting guide.
Technical snapshot
- Visible symptom: default search engine or search shortcut named
MINERSEARCHorMinerSearch. - Common redirect result: address-bar searches are routed to Bing, Yahoo, or another search provider after passing through an unwanted setting.
- Browsers to check: Firefox first, then Chrome and Edge if sync or multiple profiles are active.
- Likely control points: browser extension, search shortcut, homepage/new-tab value, managed policy, or a Windows app that reinstalls browser settings.
- Main risk: traffic routing, tracking, unwanted ads, and repeated restoration of a search provider you did not choose.
MinerSearch tool vs. MinerSearch redirect
The name matters because search results mix two different intents. The legitimate MinerSearch project is a Windows utility with releases and developer notes; it is not the same thing as a browser search provider suddenly appearing inside Firefox. If you intentionally downloaded that utility from the project page, evaluate that file separately by source, hash, signature, and scan result.
The redirect case is different. A browser search engine entry can be added by an extension, a profile change, sync data, or a policy setting. If you did not add MINERSEARCH yourself and searches now flow through it, treat the browser state as unwanted and clean it.
Symptoms to check
- Firefox, Chrome, or Edge shows MINERSEARCH as the default search engine.
- Typing into the address bar sends searches to Bing or Yahoo even after you choose another provider.
- The browser changes back after restart, profile sync, or extension sync.
- An unfamiliar extension has permission to read/change data on search pages.
- The browser says a personal device is managed by an organization.
- A recently installed free app, browser helper, or installer appeared at the same time as the redirect.
Remove suspicious extensions first
Start with extensions because a live extension can rewrite search settings after every manual fix. Remove anything installed near the time the redirect started, especially search helpers, coupon tools, PDF converters, download managers, tab managers, or extensions you do not remember approving.
- Open the extension manager in the affected browser.
- Disable suspicious extensions one by one if you need to identify the trigger.
- Remove the extension once the redirect stops.
- Restart the browser and test an address-bar search before changing more settings.
- Launch Chrome.
- Click the three dots (...) in the top right corner.
- Select Extensions > Manage Extensions.
- Click Remove next to the extension you want to delete.
Quick Access: Type chrome://extensions/ in the address bar.
- Open Safari.
- In the menu bar, click Safari and select Settings (or Preferences).
- Click on the Extensions tab.
- Select the extension and click Uninstall.
- Click the menu button, select Add-ons and themes.
- Go to the Extensions tab.
- Click the three dots (...) next to the extension and select Remove.
Quick Access: Type about:addons in the address bar.
- Launch Microsoft Edge.
- Click the three dots (...) in the top right corner.

Quick Access: Type brave://extensions/ in the address bar.
- Launch Opera.
- Click the Opera logo in the top left corner.

- Click the X or Remove button next to the extension.
Quick Access: Type opera://extensions/ in the address bar.
Open Extensions/Add-ons again and remove any entry linked to MinerSearch or clearly out of place.
Restore search and new-tab settings
After the extension is gone, clean the search settings directly. Mozilla documents that Firefox lets users change the default search engine and manage search shortcuts from the Search page in Settings [2]. Chrome also provides a settings reset path for unwanted ads, pop-ups, and malware-related browser changes [3].
- Open browser search settings and set your preferred default search engine.
- Remove
MINERSEARCH,MinerSearch, and any unfamiliar custom search shortcut. - Review homepage, startup page, and new-tab settings.

Quick Access: Type opera://settings/reset in the address bar.
After reset, verify that MinerSearch is no longer set as your default search engine or homepage.
If settings are locked or managed
A locked search engine usually means a browser policy, enterprise configuration, or unwanted Windows component is enforcing the value. On a work or school device, ask the administrator first. On a personal device, a sudden managed-browser message deserves cleanup.
- Check browser policy pages such as
chrome://policyoredge://policyfor unknown extension and search rules. - Review installed Windows apps from the date the redirect started.
- Inspect browser shortcut targets for extra URLs after the browser executable path.
- Check Startup Apps and Task Scheduler for entries that launch the browser or a suspicious updater.
- Scan the system before deleting random policy keys manually; the same app may recreate them.
Scan Windows if MinerSearch returns
If the redirect comes back after extension removal and a browser reset, assume the browser is only one part of the problem. A bundled installer or unwanted app can reinstall an extension, restore a search shortcut, or push a policy again at startup.
- Uninstall recently added utilities you do not recognize.
- Remove leftover browser profiles only after exporting bookmarks and checking sync.
- Run a security scan if the redirect started after a cracked app, fake update, or unknown installer.
- Change passwords only from a clean browser if you entered credentials on pages reached through the redirect.

FAQ
Is MinerSearch always malware?
No. The name can refer to a legitimate open-source anti-miner utility, but an unexpected MINERSEARCH browser search setting is still unwanted and should be removed from the affected profile.
Why does MinerSearch redirect to Bing?
Many hijackers route traffic through a custom search shortcut and then land on a normal provider such as Bing or Yahoo. The final search page can look familiar while the browser setting that routed the query remains unwanted.
Why does the search engine come back after I remove it?
An extension, sync profile, managed policy, or Windows startup item may be restoring it. Remove extensions first, then clean search shortcuts, pause sync for testing, and scan Windows if the value returns after restart.
Should I delete my whole browser profile?
Only if extension removal, search cleanup, policy checks, and reset steps fail. Export bookmarks first, avoid restoring suspicious extensions, and test with sync disabled before reconnecting the profile.
