From the National Crime Agency website:
The National Crime Agency is warning people they have two weeks to save their computers from a powerful malicious software attack. The malware called GOZeuS is hiding within attachments in emails and, once downloaded, enables hackers to access computers and scan them for valuable information.
If no data is found, a second malware, known as CryptoLocker, locks the computer, displays a window with a countdown, and demands a ransom to grant access again.
According to the NCA, people are asked to pay 1 Bitcoin (£200 – £300) to regain access to their files.
The NCA is advising people to make sure security software is installed and updated, by running scans and checking that computer operating systems and applications are up to date….

This page has been created to help you protect your computer, your finances, your identity and your family against a new global online threat. The threat is targeted at random private individuals and small businesses, so it is critical that you read this page and apply our advice immediately if you have a computer running any version of the Windows operating system – including Windows running as a virtual machine on an Apple Mac, any server running Windows and Windows embedded. This is not a case of isolated attacks, as over 15,000 computers in the UK alone are thought to have been already affected.
What you need to do NOW…

This warning is not intended to cause you panic but we cannot over-stress the importance of taking these steps immediately. This is because the UK’s National Crime Agency (NCA) has taken temporary control of the communications used to connect with infected computers, but expects only a very limited window of opportunity to ensure you are protected.
