How to protect USB Virus from entering your PC?

Hi friends, i have a solution for your
issue.
You can make your normal pen drive
to virus protected pen drive. for
that u want 1 pc which having
windows vista or 7 os installed.
Follow the below steps……..
1) Connect ur pen drive to pc
which having widows vista or
windows 7 operating system. (The
user must having Administrator
rights)
2) Open ‘My Computer’ & right click
on pen drive icon then select
‘Format’ option. Before formatting
you must take a back up of all of
your data because it deletes whole
data from your pen drive.
3) In Format window select file
system tab & change it to ‘NTFS’
then click on ‘Start’ to start
formatting.
4) After formatting done close the
format window & open your
pen drive.
5) create one folder in pen drive &
rename it to ‘secured’.
6) Back to ‘My Computer’ & again
right click on pen drive & now
select ‘Properties’ tab.
7) In properties window select
security tab then click on edit &
tick on ‘Deny’ for ‘Write’ permission
then press ok to apply the settings.
8) Open pen drive again, right click
on ‘Secured’ folder select
‘Properties’ then ‘Security’ tab.
again click on ‘Edit’ tab & set ‘Allow’
permission to ‘Full Control’ then
click ok to apply settings.
9) Open ‘Secured’ folder, create
one folder into that & rename it to
‘Secured.exe’.
10) Right click on ‘Secured.exe’
folder select ‘Properties’ & make it
hidden by selecting ‘Hidden’
attribute then select ‘security’ tab
click on ‘Edit’ & set ‘Deny’
permission to ‘Full Control’ .
10) Press ‘Ok’ to apply the settings.
Now your pen drive is virus
protected. but u can’t copy files
into that directly. u need to copy all
of your files to the secured folder & I
re-command that copy your software
setup files to the zip folder so,
virus can’t access software’s exe
files
