What's going on

A reset is the quickest fix for hijacked search engines, unwanted startup pages and misbehaving settings. Bookmarks, history and passwords stay. Cookies and site data are cleared, so you may need to sign in again.

How it shows up

  • Search engine or homepage changed without permission.
  • Unexplained pop-ups or redirects.
  • Chrome behaving oddly after experimenting with settings.

What causes it

  • Extensions or software changing settings.
  • Accidental or experimental flag changes.

How to fix it, step by step

  1. Desktop resetchrome://settings/reset → Restore settings → Reset settings.
  2. Reset flagsOpen chrome://flags → Reset all if you changed experiments.
  3. Review extensionsRemove unknown extensions; re-enable trusted ones.
  4. AndroidSettings → Apps → Chrome → Storage → Clear storage (signs you out; synced data returns after sign-in).
  5. Managed by organisation?If settings say 'Managed by your organisation' on a personal PC, scan for adware.
How to confirm the fix: Chrome opens with the default new tab page and Google search (or your choice).
