Autorun. inf immune attack and defense

As for the previous autorun. inf immunization, it is completely useless,
For example:

@ Echo off
CD/d h:
MD autorun. inf
MD autorun. inf/test ../
Attrib autorun. inf + S + H + R
Echo y | CALCs autorun. inf/d everyone

If the virus is detected, use the following script to remove the virus.

@ Echo off
CD/d h:
Echo y | cacls autorun. inf/g administrator: F permission
Attrib-s-h-r autorun. inf
Rd autorun. inf/S/Q

Therefore, LZ may use rmdir/s (same as del) when it finds that all directories are missing)
The previous immunity can be deleted, leaving the read-only file of autorun. inf.
The virus is running in the memory,
So, you refresh the del once, the file is out, and refresh it a few seconds later. The virus in the memory is automatically replaced with autorun. inf, so it's gone.
