first you can try booting into safe mode and try deleting it from there...
if that does not work, create a new folder on your desktop dont name it then drag and drop it onto the file that wont delete now you should be able to delete it.
if that does not work either, try the following link..
let us know if this was helpful
I downloaded a rar file (15 mb) and once I unpacked it on my desktop (it would show 0 mb when I tried the properties tab) it would not allow the contents of the folder to be seen nor to be delete it. The message I got was ?unable to delete the file? and ?it is used by another program?. I tried the following to delete the file to no avail however: 1. DOS commands 2. The ?Unlocker? software 3. Tried to see what new files were created on that day (could not find anything suspicious) so I can delete them 4. Looked at the startup programs (could not find it there) 5. The ?restore at any earlier date? feature of windows XP 7. Looked in the registry (could not find anything) 8. Tried to see what processes were running so I can terminated it but could not locate anything 9. Tried the Ultimate Troubleshooter software to locate any suspicious running processes 10. PC tools ?Spyware doctor with Antivirus? and ?Threadfire?, Eset antivirus (it could not scan the folder because it appears to be locked), Avir antivirus, Panta microscan and XoftspySE and I got no malware detection what-so-ever.
Further info is that the folder can be moved around (Into other directories and folders but not into the trashcan) and it has the ?Read only? indication checked (But it cannot be unchecked)
I have administrator privileges on the windows xp system and if anyone could help I would appreciate it.
