Identify what is happening before trying a removal method. This guide helps you restore a Chrome homepage you prefer and investigate persistent unwanted behavior. It does not classify Mintnav as malware, a browser hijacker or harmless software without device-specific evidence. We have not analysed an executable, inspected its traffic or performed a forensic examination. ## What does the name on the homepage tell you? A URL displayed when you tap Home identifies the page that opened. It does not by itself identify the software responsible for choosing it or establish what that software does. First record the full address, where it appears and whether it returns after you change the setting. Google lists repeated homepage or search-engine changes among symptoms that may accompany unwanted software. That is a reason to investigate persistent changes, not proof that a particular homepage is a virus. [Chrome's unwanted-software guidance](https://support.google.com/chrome/answer/2765944?co=GENIE.Platform%3DAndroid&hl=en). ## Identify the behavior before changing settings | What you observe | First place to check | What it does not establish | | --- | --- | --- | | A page opens after tapping Home | Chrome's homepage setting | That an installed app is malicious | | An unwanted notification appears | The notification's sending app or website permission | That changing the homepage will stop it | | Search results use another provider | Search-engine settings | That the homepage setting controls search | | A changed setting keeps returning | Installed apps, management policy and vendor support | Which component caused the change | Use the table to choose one investigation at a time. Record what changed and what happened afterward. Altering several unrelated settings simultaneously makes it harder to identify the cause. ## Change Chrome's homepage on Android Google documents the following route for Android Chrome: open Chrome, use the More menu, select Settings and open Homepage under Advanced. Choose Chrome's homepage or enter the page you want. Labels can vary with the version and device configuration. [Official Chrome homepage instructions](https://support.google.com/chrome/answer/95314?co=GENIE.Platform%3DAndroid&hl=en). Close the settings screen, open a new browsing session and tap Home again. Confirm that your preferred page opens. If you are seeing an existing tab rather than the Home page, close or navigate that tab separately; do not assume a retained tab means the setting failed. If the browser or device is managed by an organization, use its support process. Google notes that administrators can control relevant browser settings. Avoid trying to defeat a management policy to change a homepage. ## Handle site notifications separately If the problem is an unwanted website notification, inspect that site's notification permission and turn off the unwanted permission. Google's Android unwanted-software guide distinguishes website notifications from app-removal steps. A homepage change does not necessarily change a site's existing permissions. Do not tap a notification's demand to install a cleaner or update. Open the relevant browser or app settings independently. An alarming page claiming to have detected viruses is not the same thing as a security finding from your device's established protection service. ## If the homepage keeps changing Record the browser version, operating-system version, update timing and recently installed apps. Capture a screenshot of the setting before and after the recurrence, omitting personal information before sharing it with support. Google's Android guidance describes using safe mode and removing recently downloaded apps one at a time when unwanted software is suspected. The safe-mode procedure varies by device, so use your manufacturer's current instructions. Do not disable system services or uninstall essential components based solely on a forum label. Review the apps you recognize and the source from which you installed them. If an app is needed for work, check with your administrator before removing it. Keep a record of changes so that a mistaken removal can be addressed through a verified support route. ## Use established protection and support Google Play Protect checks apps for potentially harmful behavior and can warn about, disable or remove harmful apps. You can review it in the Play Store. A scan is one useful check; do not treat the absence of a warning as a complete forensic assessment. [Google Play Protect documentation](https://support.google.com/googleplay/answer/2812853?hl=en). Keep the browser and system updated through their normal update channels. If changes persist, contact the device maker or your organization's support team with the observations you recorded. Avoid granting remote control or sending passwords to someone who contacts you unexpectedly. ## If you entered sensitive information A homepage preference can be corrected in settings, but information entered into an untrusted page requires a separate response. Identify the affected account, contact its provider independently and follow its recovery instructions. Review sessions and recovery details where available.

For broader account and app controls, see the [personal information privacy guide](https://theinfosiast.com/data-privacy-in-the-digital-age-tips-for-protecting-your-personal-information/). Do not assume changing the homepage reverses an earlier disclosure. ## A short troubleshooting record - Full URL and action that opens it. - Browser, operating system and device versions. - Whether the issue is a homepage, search result, notification or redirect. - Setting changed and result after the change. - Recent installations or updates and any protection warning. - Verified support case reference if the issue persists. ## Glossary - **Homepage:** the page selected for the browser's Home action. - **Redirect:** navigation that sends you to another address. - **Site permission:** access granted to a website for a feature such as notifications. - **Malware diagnosis:** a conclusion about harmful software that needs evidence beyond a displayed website name. ## Sources and editorial review Updated 1 October 2026.

The Technical Taxonomy The single most common forensic error end users make when confronting a homepage change — for example, the homepage being reset to Mintnav or an equivalent search portal — is classifying the behavior as a "virus infection." In endpoint security engineering terms, this classification matters because remediation paths diverge sharply depending on what mechanism actually mutated the browser configuration. A **virus**, strictly defined, is self-replicating code that attaches itself to host executables or documents and spreads by infecting other files. A **trojan** masquerades as legitimate software to gain execution but does not necessarily self-replicate. Neither definition describes the typical homepage hijacker. What actually changes your startup page in the overwhelming majority of cases is a **Potentially Unwanted Program (PUP)** — sometimes called a potentially unwanted application (PUA) — specifically a commercial *search-traffic arbitrage* component. Its economic model is straightforward: - **Ingress via bundling.** The PUP ships inside a free-software installer bundle (PDF converters, media players, driver updaters), behind a custom-installer wrapper with default-on consent checkboxes, or as an OEM/partner preconfiguration on new devices. - **Configuration mutation, not code injection.** It writes homepage and default-search-provider values into browser settings, policy stores, or extension manifests. No executable payloads are dropped onto host binaries; no replication occurs. - **Affiliate search-feed monetization.** Every subsequent search routes through a feed aggregator (the "search feed") that pays the hijacker operator per-query or per-install revenue, typically 0.5–3 USD per thousand monetized searches in mature markets, adjusted by geo-tier. The forensic consequence: because there is no resident malicious binary in many hijack scenarios, antivirus scanners frequently report nothing — detection engines score the behavior under "browser modifier" heuristics rather than virus signatures. Removing it therefore means reverting configuration state across several persistence layers, which the rest of this section documents layer by layer. ### Detection Consensus Matrix | Property | Classic Virus/Trojan | Commercial Hijacker / PUP | | --- | --- | --- | | Self-replicates to files/network shares | Yes (virus) / No (trojan) | No | | Primary artifact on disk | Infected binaries, droppers | Extension package, config keys, scheduled task or none at all | | Typical AV/EDR verdict | Malware signature hit | PUA/badger heuristic; often undetected | | Persistence mechanism | Run keys, services, WMI subscription | Policy store, forced extensions, shortcut args, profile lock file | | Revenue model | Ransom, data theft, botnet lease | Per-query affiliate search revenue | | Remediation surface | Filesystem + memory + scheduled persistence | Browser policy/config state only, in most cases | ## Layer Map: How Hijackers Achieve Persistence Across Platforms A homepage "reset" that survives manual correction almost always indicates the change is being re-applied by something upstream of the user-visible settings UI. Modern Chromium-based browsers treat managed configuration as authoritative: values delivered via enterprise policy cannot be overridden from `chrome://settings`, and the settings card displays a "*This setting is managed by your organization*" annotation — on a consumer machine with no actual IT department, which is itself the diagnostic smoking gun. ### Windows Registry Policy Keys (Chromium Browsers) The canonical hijacker fingerprint on Windows lives under the policy hives for Chrome and Edge: ``` HKLMSoftwarePoliciesGoogleChromeRestoreOnStartupURLs HKCUSoftwarePoliciesGoogleChromeHomepageLocation HKLMSoftwarePoliciesMicrosoftEdgeDefaultSearchProviderSearchURL HKLMSoftwarePoliciesGoogleChromeExtensionInstallForcelist ``` Mechanically, these keys are read at browser startup with higher precedence than profile preferences stored in the user's `Preferences`/Secure Preferences JSON blob. **RestoreOnStartupURLs**, combined with **RestoreOnStartup = 4**, forces a specific URL set to open every launch. **HomepageLocation** pins the home button target. **DefaultSearchProviderSearchURL** rewrites default search: the value typically contains a template such as `https://hijacked-portal.example/search?q={searchTerms}&src=aff`. **ExtensionInstallForcelist** is the most aggressive layer — it specifies extension IDs pinned to private CRX update URLs, which Chrome will silently install and reinstall even after the user removes them from `chrome://extensions`, because forced installs bypass uninstall permission. ### macOS Configuration Profiles (.mobileconfig) On macOS, hijacker distribution kits occasionally deploy signed or unsigned configuration profiles under `/Library/Managed Preferences` (or stage unsigned payloads via defaults-written keys) that enforce identical Chromium policies through Apple's managed-preference channel: `com.google.Chrome` domains carrying `HomepageLocation`, `RestoreOnStartupURLs`, and forced-extension dictionaries. Rogue MDM enrollment on Android devices works analogously: an app granted device-administrator or profile-owner rights can re-pin browser settings and reinstall webviews across resets. On all three platforms the architectural principle is identical — *move the configuration write-head above the browser's own UI trust boundary*. ### Cheap-but-Persistent Layers Users Overlook - **Modified .lnk shortcut arguments.** The desktop/taskbar launcher itself carries the payload: target becomes `"C:...chrome.exe" https://mintnav-clone.example`. Every click "restores" the homepage even though no setting was ever persisted. - **Rogue Service Workers.** A malicious extension or a granted push-permission site registers a service worker that intercepts network responses and rewrites search-result URLs client-side, surviving as long as the SW registration does. - **Push-notification permission grants.** Not strictly a hijack of the homepage, but functionally adjacent: Notification API subscriptions (HTTP/2 server push over endpoints like `fcm.googleapis.com`) deliver recurring ad payloads until revoked at origin level. - **OEM partner preloads.** Factory bookmarks, default browser choice, and pre-seeded startup pages shipped with consumer hardware are contractual, not infectious — distinguishing these from active hijacks is step one of triage. ## Forensic Inspection Workflow: Windows / PowerShell Recipe The following sequence assumes Chromium browsers plus Firefox on a Windows endpoint. Run from an elevated PowerShell session; every command is read-only until the final remediation block. ``` # 1. Enumerate Chrome policy keys (repeat path swap for MicrosoftEdge) Get-ChildItem 'HKLM:SoftwarePoliciesGoogleChrome' -Recurse -ErrorAction SilentlyContinue | Format-List Get-ItemProperty 'HKCU:SoftwarePoliciesGoogleChromeExtensionInstallForcelist' -ErrorAction SilentlyContinue # 2. Inspect shortcut target arguments across user + public profiles Get-ChildItem "$env:USERPROFILEDesktop","$env:PUBLICDesktop", "$env:APPDATAMicrosoftInternet ExplorerQuick Launch" -Filter *.lnk -Recurse | ForEach-Object { $s = (New-Object -ComObject WScript.Shell).CreateShortcut($_.FullName) [PSCustomObject]@{Lnk=$_.FullName; Target=$s.TargetPath; Args=$s.Arguments} } | Where-Object {$_.Args} | Format-List # 3. List scheduled tasks and services created outside known publishers (persistence sweep) Get-ScheduledTask | Where-Object {$_.State -ne 'Disabled'} | Select-Object TaskName, TaskPath | Format-Table # 4. Dump Firefox prefs for hijack markers Select-String -Path "$env:APPDATAMozillaFirefoxProfiles*prefs.js" ` -Pattern 'homepage|keyword.URL|browser.startup.page' ``` **Interpretation rules.** Any `ExtensionInstallForcelist` entry on a consumer machine is presumptively hostile — legitimate enterprises use it, home users essentially never do. A shortcut `Arguments` field containing an http(s) URL is a hijack regardless of what the browser settings claim. Policy keys whose values reference search-feed domains with query parameters such as `src=`, `subid=`, or base64-blob tokens are affiliate-arbitrage fingerprints. ## Forensic Inspection Workflow: macOS Terminal Recipe ``` # 1. List installed configuration profiles (system + user scope) sudo profiles list -output stdout # newer macOS syntax: profiles show # inspect ManagementPayloads for Chrome policies # 2. Read enforced Chromium preferences from managed-preferences mount defaults read /Library/Managed Preferences/com.google.Chrome 2>/dev/null | grep -Ei 'HomepageLocation|RestoreOnStartup|SearchProvider' # 3. Sweep LaunchAgents/LaunchDaemons for unknown persistence jobs ls -la /Library/LaunchAgents ~/Library/LaunchAgents /Library/LaunchDaemons 2>/dev/null # 4. Inspect Firefox prefs and Chromium profile Preferences JSON grep -Ei 'homepage|startpage' ~/Library/Application Support/Firefox/Profiles/*/prefs.js python3 - <<'PY' import json, glob for p in glob.glob( '/Users/*/[LR]*/Application Support/Google/Chrome/*/Preferences'): d = json.load(open(p)) ss = d.get('session', {}).get('restore_on_startup') if ss: print(p, '-> restore_on_startup:', ss, 'urls:', d.get('session', {}).get('startup_urls')) PY ``` Removal on macOS: delete the offending payload with `sudo profiles remove -identifier `, clear the corresponding defaults keys with `defaults delete com.google.Chrome HomepageLocation` (repeat per key), then restart the browser — policies are re-read at process launch, not live-patched mid-session. ## In-Browser Diagnostic Pages: The Ground Truth Layer Before touching anything on disk or in the registry, interrogate the browser's own telemetry surfaces. These internal pages reveal which layer owns the current homepage value: | Diagnostic Page | What It Reveals | Hijack Indicator | | --- | --- | --- | | `chrome://policy` | All active policies with scope (machine/user) and source | HomepageLocation / RestoreOnStartupURLs present on a consumer box; "OK" status for policy payloads the user never installed | | `chrome://extensions` | Installed extensions, permissions, forced-install badge | Extensions that cannot be removed ("installed by your administrator"); unknown IDs reading site data | | `chrome://serviceworker-internals` | All registered service workers per origin, with scope and script URL | Workers scoped to `/` on unrelated origins; fetch handlers rewriting URLs | | `edge://policy`, `about:support` (Firefox) | Edge enterprise policy mirror; Firefox's modified-preferences list + reset buttons | Same signature keys as Chrome table row 1; Firefox rows marked "Set by an extension" or locked user_pref lines | In `chrome://policy`, click *Reload policies* after any registry cleanup — Chromium caches policy state in memory until refresh. In Firefox's `about:support`, the "Important Modified Preferences" and "Extensions" tables let you reset individual prefs without hand-editing files. ## Clean Removal, Ordered by Dependency Layer The correct remediation order is top-down through the trust hierarchy: remove enforcement first, then configuration, then extensions, then persistence wrappers. Reversing this order causes immediate re-infection during cleanup. ``` # WINDOWS — PowerShell (elevated). Substitute Edge paths as needed. # Step 1: Break forced-extension pinning FIRST (prevents reinstall-on-remove) Remove-Item 'HKCU:SoftwarePoliciesGoogleChromeExtensionInstallForcelist' -Recurse Remove-Item 'HKLM:SoftwarePoliciesGoogleChromeExtensionInstallForcelist' -Recurse # Step 2: Remove homepage / search-provider / startup policy keys $keys = @( 'HKCU:SoftwarePoliciesGoogleChromeHomepageLocation', 'HKCU:SoftwarePoliciesGoogleChromeRestoreOnStartupURLs', 'HKCU:SoftwarePoliciesGoogleChromeDefaultSearchProviderSearchURL', 'HKLM:SoftwarePoliciesMicrosoftEdgeDefaultSearchProviderSearchURL' ) foreach ($k in $keys) { if (Test-Path $k) { Remove-Item $k -Recurse } } # Step 3: Repair shortcut targets (strip injected URL arguments) Get-ChildItem "$env:USERPROFILEDesktop","$env:PUBLICDesktop" -Filter *.lnk | ForEach-Object { $s=(New-Object -ComObject WScript.Shell).CreateShortcut($_.FullName) if ($s.Arguments -match '^https?://') { $s.Arguments=''; $s.Save(); Write-Output "Cleaned $($_.Name)" } } # Step 4: Verify empty state, then relaunch browser and reload chrome://policy Get-ChildItem 'HKCU:SoftwarePolicies','HKLM:SoftwarePolicies' -Recurse | Format-Table FullName ``` After registry cleanup: open `chrome://extensions`, remove the hijacker extension manually (it should now be uninstallable), visit `chrome://serviceworker-internals` and unregister any workers belonging to suspicious origins, revoke site notification permissions via Settings → Privacy → Site settings → Notifications, and only then reset homepage/default-search values in `chrome://settings`. If a value refuses to persist, return to `chrome://policy` — something upstream is still enforcing it. ### Empirical Comparison of Remediation Approaches | Approach | Typical Success Rate vs Policy-Layer Hijacks | Residual Risk | | --- | --- | --- | | Settings-UI-only reset (no policy cleanup) | Low — reverts until next launch when a policy key remains | Immediate re-hijack; user concludes "virus" persists | | Third-party "cleaner" utility suites | Moderate for known signatures; blind to custom policy keys and shortcut args | Frequently bundles its own PUPs or upsells; scamware vector itself | | Native diagnostic pages + ordered native removal (this guide) | High — addresses every enforcement layer deterministically | Requires reading values before deleting them (avoid nuking legitimate enterprise keys) | | Full profile reset / fresh browser profile | Very high per-profile, but machine-level HKLM policies and .lnk wrappers survive | Loss of saved sessions, logins; does not fix OS-level persistence | ## Prevention Engineering: Closing the Ingress Vectors Sustained hygiene is cheaper than repeated forensic sweeps. Three durable controls neutralize nearly all PUP ingress: - **Installer discipline.** Reject bundled-offer checkboxes during freeware installs; prefer vendor-direct or package-manager distribution (winget on Windows, brew on macOS) where wrapper installers with consent screens cannot interpose themselves. - **Permission minimization.** Treat site notification prompts as deny-by-default, audit `chrome://serviceworker-internals` quarterly for unexpected scopes, and never grant an unknown extension the "read and change all your data on all websites" permission class — that scope is what enables client-side search rewriting. - **Policy monitoring.** On shared or family machines, a one-line check for foreign policy keys takes milliseconds to run and catches hijack attempts at write-time: ``` reg query HKLMSoftwarePolicies /s && reg query HKCUSoftwarePolicies /s ``` Empty output on a consumer device is the healthy baseline; anything present should be identifiable to its installer origin. ### Decision Flow Summary Triage in three questions. First: does `chrome://policy` show homepage/search policies? If yes, this is a policy-layer hijack — remove enforcement keys before touching settings UI. Second: do shortcuts carry URL arguments or does `ExtensionInstallForcelist` contain entries? Then wrapper/persistence cleanup precedes any settings correction. Third: if none of the above, check service workers and notification grants, then fall back to profile-level reset with machine-level sweep as final verification. The unifying principle across Windows registry hives, macOS managed preferences, Android device-admin rights, and Chromium's own internal pages is that browsers honor whichever configuration authority sits highest in the stack — so find the topmost writer, demote it, and only then reassert your own preferences.
