I experienced this kind of situation few days before.

Situation:Each directory was hidden,and a new made same name file shortcut were made.If i click into the shortcut, the directory sometimes correctly showed and sometimes not.
By checking ,i found a directory shortcut I've never seen called '8585485', and it contained a .exe file.
Solution:Backup ur file immediately as u can, then,

Win vista/7:execute cmd
-> cd %PUBLIC%

->REG DELETE HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Run /v "Java Update Manager" /f

->REBOOT ur PC
->Execute cmd

-> cd %PUBLIC%
-> del /f /s /q /a:s jusched.exe}
-> X: (X=ur n9's drive)
-> cd \8585485
-> del /f /s /q /a:s *.exe
-> cd \
-> attrib -R -A -S -H /S /R

Finally,remove the .ink file urself.
This is my experience,it is annoying to clear device twice before i know the solution.
