A website says I must install a browser update or video player. Should I?

Reviewed answer

Use the browser's own update controls, not an installer offered by an unrelated page.

Close the page and leave its download unopened.
Check for updates inside your browser, operating system, or device's official app store.
If you ran the downloaded installer, stop sensitive activity and use official device support to check for unwanted software.

The page asks you to disable security, run commands, or install a profile before continuing.
