Locked folder with virus - delete

Question

I have a folder on a USB stick that picked up a virus when connected to a PC.
It appears as a zip folder and is locked. I cannot unlock it and cannot trash it.
Is there a way to force delete such a folder? I wish to continue using the stick and do not want to transfer the virus to other PC users.
Thanks

use searchlight to find terminal (or click on /Application/Utilities/Terminal.app )
WARNING: NEVER EVER TYPE sudo rm -rf / and press enter unless you know what you are doing
(instructions and comments are written after // the rest are commands).
//hit enter after each command typed.
//commands are case sensitive.
//go to the path were your pendrive is mounted by doing this
cd /Volumes
ls
//a list of folders will appear, verify the name of your pendrive is listed there (usually the partition name, if you pendrive is mounted as Frenchchrispen, type the following)
cd Frenchchrispen
ls
//a list of files and folders from that pendrive's mounted partition will be displayed, noticed the name //of the folder your want to delete then do
//ABSOLUTE CAUTION HERE KNOW WHAT YOU ARE TYPING, MAKE SURE IT IS THE FOLDER NAME YOU WISH TO DELETE THAT IS TYPED THERE
//NOTE: if you folder name contains special characters or space, type the name between double quotes " "
sudo rm -rf foldername_i_wish_todelete
//that should do the trick, if ever it is complaining about sudo not found, try just rm -rf or
su
cd /Volumes/Frenchchrispen
rm -rf foldername_i_wish_todelete
