random website opens every time I start my browser

Both browsers doing it at once usually means it's not an extension, it's something outside them. Check these: - Right click the browser shortcut you launch from (taskbar too) > Properties. Look at the Target box. If there's a web address stuck on after chrome.exe or msedge.exe, delete it. That's a very common trick and it survives any settings change. - Type chrome://policy in Chrome. If it lists policies on a home PC, or Chrome says 'managed by your organization', something installed them, and that's adware. - Settings > Apps, sort by install date, uninstall anything you don't remember adding around when it started. Then run a full scan with Windows Security. Extensions still worth a look, but I'd bet on the shortcut.
