How To Protect USB Drive From Virus When Attached To Infected Computer

Hi friends, i have a sloution for protecting pen drives from viruses.
You can make ur normal pen drive to virus protected pendrive & it dosen't require any software. For that u want 1 pc which having windows vista 0r 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 pendrive icon then select 'Format' option. Before formatting you must take a back up of all of your data because it deletes whole data from ur 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 ur pendrive.
5) create one folder in pen drive & rename it to 'secured'. (U can use zip folder also if ur using it, u no need to apply 10 & 11th step.)
6)some viruses are caused to hide the data. so, we need to protect our 'secured' folder. so, create one shortcut for secured folder. for that right click on 'secured' folder select 'send to desktop (create shortcut)' shortcut will be created on desktop. move it to pen drive. (This shortcut will useful if ur secured folder will made hidden by viruses in future)
7) Back to 'My Computer' & again right click on pendrive & now select 'Properties' tab.
8) In properties window select security tab then click on edit & tick on 'Deny' for 'Write' permission  then press ok to apply the settings.
9) Open pen drive again, right click on 'Secured' folder select 'Properties' then 'Security' tab. again click on 'Edit' button & set 'Allow' permission to 'Full Control' then click ok to apply settings.
10) Open 'Secured' folder, create one folder into that & rename it to 'Secured.exe'.
11) Right click on 'Secured.exe' folder select 'Properties' & make it hidden by selecting 'Hidden' attribute & apply it then select 'security' tab click on 'Edit' & set 'Deny' permission to 'Full Control'.(after that virus can't create exe file on secured folder) Then press 'Ok' to apply the settings.

Now ur pen drive is virus protected & it works in all windows nt based operating systems, but u can't copy files into that directly. u need to copy all of ur files to the secured folder. I advice that copy ur software setup files to the zip folder so, virus can't access software's exe files & if possible do not create more folders so, virus can't create new viruses (exe files) into ur folders. If you use zip folder in the exchange of normal folder (secured folder) then ur pendrive will be more secure from the viruses. It takes some more time for copying data in zip folders but it more secure than the normal folders & it gains more storage space because it compress data while copying.
