What is malware?
The term malware (short for malicious software) is the collective name for any harmful or damaging software, often designed for criminal purposes. It disrupts and manipulates normal computer operation to steal information and facilitate fraud.
Malware can often surreptitiously install itself on your computer without you noticing, usually when you open an infected attachment to an e-mail or open a link to an infected website.
Criminals are increasingly turning to banking malware, computer viruses specifically written to dupe people banking online. Fraudulent payment orders are submitted or confidential information is stolen without you noticing.
Certain types of malware, known as ransomware, encrypt your files. Next, you’re asked to pay a ransom to have them released.
How can I protect myself against malware?
Be careful when you use the Internet, e-mails and external carriers.
- Only surf to known and trusted websites.
- Never download a file from an unknown source or if you don't know the sender.
- Never simply connect a USB stick to your PC. Never just connect your personal USB stick to any device whatsoever. Scan any suspect USB sticks with your antivirus tool.
Ensure that you have a good and up-to-date security package on
all devices used online.
- Install a good antivirus software and regularly scan all of your devices.
- Always use the most recent version of your operating system (with the correct settings, your computer will automatically carry out this update). Also, always use the latest version of your Internet browser.
- If your company uses a local network, make sure it is adequately protected. And always use a secure Internet connection when you connect to a wireless network (for example, by using a password).
- Regularly back up all of your files and ask your colleagues to do the same. Make sure that the device that contains these back-ups is always disconnected from the network.
- Never save your login details on a public PC.
