The National Crime Agency (NCA) is asking people to protect themselves from malware after a computer network known as Avalanche has been taken down.Â
Avalanche, which was set up in 2009, was used to send out millions of fraudulent emails weekly enabling cybercriminals to steal personal information such as financial details. At any given time up to 500,000 computers worldwide are believed to have been carrying infections distributed through the Avalanche network.
On 30 November 2016 a global operation by police forces from more than 30 countries, including the UK, resulted in criminal enterprises losing access to Avalanche.
Malware on the Avalanche system concentrated on but was not limited to Windows PC vulnerabilities.
To help protect yourself from the threat of malware you should ensure that you always download the latest software and app updates which contain vital security upgrades to help protect your devices. Â
Remember if an email or SMS text message is unexpected or you do not recognise the sender always take care not to open attachments, or click on links.
