Protect Your PC

Malware, a shortened version of ‘malicious software’, is a computer virus that can be installed on your computer without you realising. It is designed to enable fraudsters to steal your personal or financial information or perform unauthorised actions on your computer.

Malware can sometimes get on your computer if you visit untrustworthy websites, click links in spam emails or download a pirated computer file.

A common type of malware is a called a ‘Trojan’. This can install a ‘keystroke logger’ on your computer which records the letters and numbers you type on your keyboard. Then, when you access an online bank account, the keystroke logger can record your login information.

Other Trojan malware can create a bogus pop-up webpage which appears in front of a genuine online banking login website, tricking you into entering your login details into a fraudulent website.

Other types of malware can alter webpages, meaning they are able to insert extra fields into an online banking website, tricking you into giving a fraudster personal information.

How to avoid this type of scam:

Be wary of

  • unsolicited emails that encourage you to click on links or open attachments. Emails containing Trojans often try to entice you to do so by pretending to include dramatic news or information.
  • websites that launch a program unexpectedly or that create a lot of activity on your internet connection as it downloads computer files.
  • downloading executable files (.exe) or zip files (.zip) from the internet or emails, especially from an unknown source.


  • make sure that you have anti-virus and browser security software installed with the latest updates, and regularly run scans of your computer.
  • installing a firewall and anti-spyware programme also helps protect you from malware.
  • check that you have the latest operating system and web browser security updates installed.
  • if you detect malware on your computer, try to remove it using anti-virus software, or speak to your computer or software supplier’s support centre.

If you suspect that your computer may have been infected with malware and you have used any online banking services, contact your bank immediately.
