Quick Determination of programs infected

First, use the CMD command in the system, that is, the DOS command to create a 0-byte EXE and COM program. The specific command is as follows:

Cd.> c: virtest.exe & cd.> c: virtest.com
Or
Type nul> c: virtest.exe & type nul> c: virtest.com

The preceding two commands can create a 0-byte file named virtest in EXE format and a COM file under the root directory of the C drive. Of course, you can also create a file to any location. You can create and cut the file first, as long as it does not affect the use and viewing. It can also be stored in other non-system partitions ,. Because the monitored file size is 0 bytes, if the virus is infected with an EXE or COM program, the size of the two files you created will be changed, the difference between 0 and 1, I believe everyone can see it.

This is a tip to quickly determine whether the virus is infected with EXE.
