008.dat is a dangerous file, which can be easily used for initiating serious problems on computer. According to security experts, this file belongs to a parasite, which is called MalwareDestructor. However, hackers might have involved it to the functionality of other viruses as well. Just like MalwareDestructor virus, these threats belong to 'rogue anti-spyware' category. That means they display fake alerts that report about computer issues and then offer their paid license, which is typically presented as the only tool that is capable of fixing computer. Of course, you should never pay for MalwareDestructor's license. You should run a full system scan with reputable anti-spyware as soon as you notice alerts from this rogue.
008.dat is created as soon as PC is infected. In most of the cases it is used for degrading system's performance.
