Protecting your business


What is Malware?

  • Malware is malicious software used to infect or access your computer, including viruses, trojans, spyware, ransomware and more.
  • Fraudsters often pretend to be well-known organisations and ask you to click a malicious link or open an attachment. Your computer may be infected by following a link, downloading online attachments or opening an attachment in a phishing email.
  • Once activated, malware can redirect you to bogus screens, and display prompts and warning messages designed to persuade you to enter security information.
  • Ransomware can take control and encrypt your files and demand a ransom to release them and restore your data.
  • Once infected, your device is likely to run slowly as the malicious software works to intercept data, particularly when you’re logging in to your online accounts.

What to look out for

  • Remember, malware is often disguised behind links and offers that are designed to tempt you to click and open. Examples could be an unexpected gift or prize.
  • Malware is also hidden in prompts and links that scare you into acting. Examples include: an unsuccessful parcel delivery, health warnings, fines linked to tax or traffic violations. If you're unsure, contact the organisation independently, as they may have helpful security advice on their website warning it’s a scam.
  • Be careful of unusual emails from colleagues or messages from friends via social media, as these requests may ask you to visit a link or open a malicious attachment. Check with the individual directly as they may have had their email or social account hacked.
  • Be wary of the websites you visit, especially when downloading content that appears attractive or useful. It may be downloading potential malware to your device. Check it’s genuine and from an official source.
  • Keep your browser updated to the latest version, and run all required patches, to ensure your browser security protection is as strong as it can be.

Actions you can take now

  • Share this page with employees and colleagues so they know what to look out for. Build a culture of security awareness. To help with this, you can make use of our webinars and resources, and the advice of the National Cyber Security Centre.
  • If someone does click on a malicious link or open an attachment, encourage them to speak out as soon as possible; the quicker it’s identified, the sooner you can act.
  • Forward any suspicious emails referring to NatWest to phishing@natwest.com. Most big companies will have their own inbox for reporting phishing emails.

Always think twice and make double checking second nature
