Lock with DOS command to prevent virus from formatting the hard drive

More and more virus programs to the computer data destruction, some viruses more directly format the hard disk partition.

In fact, we can use small commands to prevent the virus program to the hard disk format, such as the destruction of operations.

Use Notepad to open the AutoExec file in the C-packing directory and add the following statement:

C: "DOSKEY format=bad command or filename!

C: "DOSKEY del=bad command or filename!

C: "DOSKEY deltree=bad command or filename!

Then save the disk and exit. When you invoke the commands such as format, DEL, deltree, and so on, you will see bad command or filename and reject the operation.
