wow, disabling files to run from the root of all drives would never, ever
fly in a corporate environment.  Although I do like the idea on stopping
autorun malware, it would work... but oh the calls to the helpdesk! ;-)  

Simply disabling autorun is a much better solution.

spreading viruses

USB / FLOPPY are attractive means for virus/worm to propagate. Here is
a workaround to stop a successful infection from happening (well ~99%
of the time least)

1. if you dont use wscript.exe disable/rename it.

2. start menu > control pannel > administrative tools > local security
policy >software restriction policy >additional rules

say if c:\ d:\ and e:\ are your fixed drives then....

right click additional rules > create path rule and create path rule
[DISALLOWED AS]

c:\*.*
d:\*.*
e:\*.*

// why let anything to execute from root of fixed drives.

for all other drives (removable/non existing) from a - z do as
a:\
b:\
f:\
g:\
........and so on. Why let anything execute from removable drive
unless you are 100% sure the pendrive is clean and from a trusted
source only.

always have file extension and hidden/protected system file to "show
by default" from folder option.

well this is it. From a personal experience i assure the above should
be the BEST solution for this problem and a extra layer of defense if
AV fails to detect it.

thanks,

"Meanwhile, the U.S. Department of Defense has temporarily banned the
use of thumb drives, CDs, and other removable storage devices because
of the spread of the Agent.bzt virus..."

There is no security through obscurity.
