Live Security Platinum has just been released. This is not a real security product. You can watch a video on how to remove this threat. http://www.removevirus.org/live-security-platinum guide will help.
Malware clients like this are very common online. Computers can be infected for many different reasons. In many cases the infected computer did not have a good antivirus client or no protection at all.
This can be a very stubborn malware virus to remove. Your efforts should be put to removing a single file from your PC. Once this is done you will have a much easier time getting rid of the rest of the virus.
One client we like is malwarebytes. The free version is not the best for protection but it’s great at removing viruses.
