How to recognise malware: signs to look for
A pop-up does not automatically mean malware, but unwanted software can cause browser redirects, slow performance and unfamiliar programs.
Common signs
- The browser opens unfamiliar pages or ads.
- Settings change or new extensions appear unexpectedly.
- Security alerts keep returning or the computer behaves unusually.
What you can do safely
- Do not click pop-ups that promise an urgent fix.
- Note what changed and when the behaviour began.
- Use your installed security software and keep Windows and the browser updated.
When to get help
- If unwanted software returns or security warnings persist, have the device checked.
- Do not enter payment details or passwords into a pop-up claiming to be support.
