hello, 
I intalled bitdefender 2013 internet security and then noticed that when i try to scan flash memory manually ,  it cause explorer crash  when i right click the flash memory icon in my computer ( only the flash memory icon )  , and tells me to report the problem or restart the explorer   .
so i tried to repair but it does not work, then i uninstall and  the problem disappears , then  i install again but the problem arises again 
any ideas !!
