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 4744 bytes, and some places have it as 4744 virus, because the virus is a variant of technology, its almost infinite variety of forms, so that the total anti-virus software, missing one or two, I do not know when they to take out, so they call it the ' ghost king' .
