Natas 病毒，长度 4744 字节，有的地方有把它称为 4744 病毒，由于病毒是用了变型技术，本身的形态几乎有无穷多种，使杀毒软件总漏掉一两个，不知什么时候又冒了出来，所以又称它为‘幽灵王’。-Natas virus, the length of 4,744 bytes, in some places it is called the 4744 virus, because the virus is a variant technology, the form itself almost infinite variety, so that anti-virus software omitted from the total 12. I do not know what time has run out, so the call 'ghost Wang'.
