Mr Kamluk explains that 'this type of malware is very dangerous because the chances of getting your data back are very low', and is 'almost the same as permanent removal of the data from your hard drive'.
Although Kaspersky Lab 'managed to offer a few ways of recovering and even decrypting your data with our decryption tools' in 2006 and 2008, says Mr Kamluk, he warns that 'GpCode is back and it is stronger than before.'
'Unlike the previous variants, it doesn't delete files after encryption. Instead it overwrites data in the files, which makes it impossible to use data-recovery software such as PhotoRec, which we suggested during the last attack.
'Preliminary analysis showed that RSA-1024 and AES-256 are used as crypto-algorithms. The malware encrypts only part of the file, starting from the first byte', explains Mr Kamluk, who says that efforts to help retrieve encrypted data has commenced, with news updates to come, and advice on what to do if already infected.
Given that all of your data, documents, music, videos, databases, photos and other personal information is rapidly being encrypted, the advice to turn your PC off as quickly as possible, even if by pulling out the power cord from a desktop computer or holding down the power button on a laptop until it reboots so you can immediately turn it off.
This is done if you see a ransom message demanding silence and money to decrypt your files, or they will (supposedly) be deleted within X number of days, with the message appearing as a pop-up notepad window with text, or as a white desktop background with text again demanding silence, and money to be wired transferred.

It's pure extortion and if you are infected, you'll definitely be wanting access to a timely, recent backup to start again, because that will be a quicker way to get going again, and is a sign that online criminals stoop to nothing in an attempt to make money, now with a cyber gun directly to your digital head.
While GpCode is aimed at Windows users, anti-malware products exist for Macs, Linux boxes, Symbian smartphones and Android smartphones for a reason - because malware can affect these platforms too, even if the scale of these threats is dramatically lesser than on Windows based PCs.
Kaspersky Lab's finding isn't the only worrying one - there are many malware attacks for banking, information and ID theft, botnet deployment and more being discovered by the world's IT security companies on a regular basis.
It's yet another wake-up call to ensure all the software on your computer is properly up-to-date, along with your operating system, and that you use a blend of compatible security solutions to best protect you from the Internet's real and present danger.
If you use Mac OS X or Linux you still need to be careful even if GpCode isn't currently targeting your operating system, the growing popularity of the Mac OS X platform and the continuing evolution of Linux mean more users for both platforms, and thus more people for cyber criminals to target, although as already noted, Windows users are at the greatest risk, with this new GpCode variant a prime example of cybercriminal intentions and actions.
So, stay safe when you surf, and whatever you do besides ensuring your computer and security programs are always up-to-date: please do remember to make fresh and regular online and offline backups!
