    Fear not! your files are just hidden, most of the times you could easily unhide them through “tool>folder options>view>show hidden files and folders but there arecases wherein you still could not seeyour files.
    Here is the step by step procedure to those files hidden by a virus.
    1. Press Start and choose run.
    2. On the dialog box type in cmd
    3. On the Command Prompt type in the drive letter followed by a colon
    4. type in “attrib *. -h -s /s /d“
    5. if problem still persists try typingin “attrib -r -a -s -h *.*“
    Always remember to place a hidden folder named “autorun.inf” on your usb stick, this usually helps prevent infection on whatever computer you insert your pendrive on (incase your drive gets contaminated)

    uncheck the hide protected operating system files in folder options selection.

    but be sure you have updated to latest virus definition and scan your computer for viruses. Some viruses don't allow you to show the hidden folders or files.

    other options. try the procedure above to another computer ^_^
