The experts are warning that there is a new computer virus, which will spread like wildfire over the next few months, and has the ability to empty online bank accounts. The virus has been named Neverquest.
But how does it work, and how can you protect yourself?
The virusExperts at Kaspersky Lab say that criminals in Russia were advertising the virus for sale in July. The sellers said at the time that the virus could break into accounts of around 100 different banks.
Now they warn that gangs have bought the virus and placed it on malicious websites - ready to infect anyone who visits the wrong page or clicks on the wrong link. Apparently there have been thousands of attempted infections around the world.
Once you are infected, if you visit one of the banks that are being targeted, the malware will control the connection to the internet, so that any usernames and passwords you enter will go straight to them. Once they have your details they can connect to the bank themselves and wire money to their own accounts.
Even if your bank is not one of the ones that the hackers have compromised, if you are infected, the code is designed to recognise when you are on a banking website - by picking up words like 'available balance' and 'account summary'. If it sees those words, the malware will send details back to the hackers, who can use the information to target your bank.
Protect yourselfEven more worrying, the experts have warned that traditional antivirus software won't protect users. Apparently the virus is so cutting edge, that it's ahead of the antivirus products. This will undoubtedly change over time as the products catch up - so it's essential to install updates.
Kaspersky Lab has also warned users to take extra care to ensure they only visit the official sites they intend to, and don't store passwords in the cookies on their computer. They add that updating to the latest version of your web browser will ensure you have added protection as the browsers develop.
