Mcafee识别到可疑病毒文件，但病毒库里没有病毒定义，就会把文件扩展名命名为vir或vxe，固建立此批处理文件，用已恢复被修改掉的exe文件
MCAFEE更名原则：
Original Renamed
Description
Not V?? V??
File extensions that do not start with v are renamed with v as
the initial letter of the file extension. For example,
MYFILE.DOC becomes MYFILE.VOC.
V?? VIR
File extensions that start with v are renamed as .VIR. For
example, MYFILE.VBs becomes MYFILE.VIR.
VIR,
V01-V99
These files are recognized as already infected, and are not
renamed again.
VIR
Files with no extensions are given the extension, .VIR.
