Malware means software and apps spread by criminals to give them access to other people’s computers and smart devices. Using malware, scammers can take over entire devices or capture users’ passwords, banking user IDs and personal data. In the worst case, this may lead to identity theft or empty bank accounts.
Malware spreads through links and attachments
Usually, scammers try to spread malware by sending scam messages with a link or attachment. A scam message may advertise anti-virus software or another solution to improve your security. Similar links may also be offered on scam websites and in pop-up windows.
Another option is that a scammer calls you first and asks you to download an app through a link sent during the call.
Be always cautious when opening links or attachments, as malware may already be downloaded on your device after a single click.
How to protect against malware
- Keep your device’s operating system, apps and software updated regularly.
- Use a firewall and reliable anti-virus software to help you recognise scam websites or malware being installed on your device.
- Don’t open any links or attachments received from unknown senders.
- Only download the apps you need from an official app store such as Google Play or Apple App Store. Don’t download any apps or software through links or attachments.
- Use multi-factor authentication whenever possible. It keeps your accounts even more secure.
- Take regular backup copies of your important files on an external hard disk or in a cloud service. This ensures that you can recover your data if malware damages your devices.
- Remember that scammers are talented in manipulation. They may try to create a sense of urgency in scam messages and calls or claim that you don’t have to worry about any warnings given by your device. Stay tough – don’t react to suspicious messages and stop any unusual calls.
