Pop‑ups or weird redirects started appearing.
Remove recently installed extensions. Then reset search/startup settings:
Chrome: chrome://settings/search (Search engine) and chrome://settings/onStartup. Reset: chrome://settings/reset.
Edge: edge://settings/search and edge://settings/onStartup. Reset: edge://settings/reset.
Firefox: Menu → Help → More Troubleshooting Information → Refresh Firefox….
