Ace Browser Removal Guide

Ace Browser is not automatically a Trojan, but you should remove it if it appeared after a quiz, download ad, bundle, or installer you did not trust. The usual problem is not one malicious file by itself; it is the whole Ace Browser or AceLauncher setup changing browser defaults, pushing search through a partner engine, adding an extension, or leaving startup items that bring redirects back after reboot.

What is Ace Browser and AceLauncher?

Ace Browser is promoted as an AI-assisted browser, while AceLauncher is promoted as a Windows desktop dock with a built-in browser. The names are close enough that users often describe the same problem as “Ace Browser,” “Ace AI,” “AceLauncher,” or “AceSetup.exe.” Official Ace pages say the browser can be uninstalled from Windows settings and that AceLauncher can be removed from Control Panel or Installed Apps.¹²

The safety decision depends on how it got there and what changed afterward. A browser you intentionally installed, tested, and can remove cleanly is a different case from a browser that appeared after an IQ-test flow, download button, fake helper, or bundled installer. In the second case, treat it like a PUA or browser hijacker until you verify the installer and clean the related settings.

The same cleanup logic applies when Pulse Browser appears unexpectedly: remove the app first, then reset default browser and search settings so the unwanted browser does not keep returning.

For a domain-only search hijack without Ace Browser or AceLauncher installed, the Nextgeeker.com redirect cleanup guide focuses on extensions, search providers, browser policies, and notification permissions.

Why Ace redirects or search changes happen

AceLauncher’s own privacy page says its default search is powered by Yahoo and that search revenue helps keep the product free.³ That does not prove every install is malicious, but it explains why users notice a sudden search-provider change and think their browser was hijacked. The same page says the search provider can be changed in settings, while AceLauncher terms mention scheduled tasks, startup behavior, and automatic updates.⁴

A third-party technical analysis also described AceLauncher as a PUP and noted leftover files, registry locations, scheduled behavior, and a Browser Shield extension. Use that as context, not as a reason to run unknown scripts from the web.⁵

How to remove Ace Browser safely

1. Disconnect from suspicious install pages. Close the quiz, download page, pop-up, or installer tab that led to Ace. Do not install a second “cleanup” utility from the same path.
2. Uninstall from Windows. Open Settings → Apps → Installed apps, search for Ace, Ace Browser, or AceLauncher, then choose Uninstall. Also check old Control Panel Programs and Features if the entry is missing.
3. End running Ace processes only if uninstall is blocked. In Task Manager, search for Ace and close the browser or launcher process. Then retry uninstall.
4. Check startup and scheduled tasks. Open Task Manager → Startup apps, then Task Scheduler. Disable Ace-related entries only when the publisher/path clearly points to AceLauncher or the same install folder.
5. Remove extension leftovers. In Chrome or Edge, open chrome://extensions or edge://extensions. Remove Ace Browser Shield or any extension installed at the same time that you did not choose.
6. Reset default browser and search. Set your normal browser as default again. In each browser, review Search engine, On startup, New tab, and Site notifications.
7. Check AppData leftovers. Look under %LocalAppData% and %AppData% for Ace or AceLauncher folders after uninstall. Delete only clearly related leftover folders, not random system files.
8. Scan for bundled PUA. Run Gridinsoft Anti-Malware to catch companion installers, browser policies, adware, and startup entries that a normal uninstall may miss.

When a scan matters more than manual uninstall

Manual uninstall is enough only when Ace disappears cleanly and browser settings stay fixed after reboot. Use a full scan when redirects return, the extension says it is managed by an organization, uninstall fails, or you also see unknown download managers, fake optimizers, coupon extensions, notification spam, or new shortcuts. Those symptoms point to a bundled PUA chain rather than a single browser app.

Gridinsoft’s own ThreatInfo record for AceSetup.exe lists the verdict as PUP.AceBrowser, with BrowseAI LLC publisher metadata and an observed 11 MB installer sample. That is useful triage context: it supports treating the installer as unwanted when it arrives unexpectedly, while still avoiding unsupported claims that every Ace-related install is a destructive malware infection.

Reset Chrome, Edge, or Firefox after removal

Do not reset the browser before you remove the program that is changing it. Otherwise the same launcher, extension, or policy can restore the redirect. After uninstall and scan, reset only the affected browser:

• Chrome: Settings → Reset settings → Restore settings to their original defaults.
• Edge: Settings → Reset settings → Restore settings to their default values.
• Firefox: Help → More troubleshooting information → Refresh Firefox.

If search still changes after the reset, use the broader browser redirect cleanup checklist to check policies, sync, shortcuts, and notification permissions. If the suspicious item behaves like a rogue browser rather than a search-only redirect, compare it with the Carbonate Browser and OneStart Browser cases.

How to avoid the same install path

• Download browsers only from the official site you intended to visit, not from quiz pages, fake update buttons, ad pop-ups, or “required helper” prompts.
• Use custom install mode and decline extra browsers, search assistants, docks, coupon tools, and “recommended” extensions.
• Do not grant admin approval to an installer unless the publisher and product match what you meant to install.
• Keep a restore point before testing unfamiliar browsers or launchers.
• After a surprise install, check accounts only if you entered passwords into the new browser or extension while it was active.
