You frequently find that you are being sent to a different web page than the one you are trying to reach.

Whether this is on the internet or not.

If you are using a Laptop, phone or tablet, and not running lots of programs at once.

  1. You’ve recently opened a dodgy attachment in a phishing email.

If you open an attachment or click a link in an email from a source you don’t trust (or a source that isn’t authentic) then you could be downloading malware onto your device.

If your emails are infected with malware it can take control of your emails and make you send malicious emails out to all your contacts.

If your PC is locked and asks you for money to unlock your PC, you have ransomware.
