How do I delete a mystery file?

I seem to have picked up some kind of file that I cannot delete from my computer.  I believe it may have "infiltrated" my system through MSN messenger, posing as a friends message.  It is now showing as a program my friends MSN name is "icklebaino" and it seems the program is called icklebaino@hotmail.  I have tried deleting it but windows states cannot delete access denied, the program may be moved to different locations however.  It seems to be an MS DOS application with a version stating "The RPMiSO Group".  I have used norton anti virus on it and it is not showing as a virus.  Also used spybot and it not showing as spyware.  Please can you help me remove the item.

Have you tried deleting that file in Safe Mode or maybe even the command prompt (recovery console)?

If those won't work, try using a program like KillBox:

Download KillBox  Run KillBox and check the box that says 'End Explorer Shell While Killing File'.  Next click on 'Delete on Reboot'.  For each of the following files below, check the box that says 'Unregister .dll Before Deleting' if it's not grayed out.  Copy and paste each of the following into KillBox (hitting the X button for each file - choose NO when it asks if you want to reboot):

...just copy and paste the full path of that mystery/bad file you want to delete...

For example, you will paste something like this in it if the bad file was called bad.exe and located in c:\windows\system32


Then hit the round red button with a white X to delete it.  Make sure you checked all those options mentioned above.
Hopefully the above suggestions helped you get rid of the mystery file.

If not, you can try the following:

Modify the security settings on the file so that no one (not even system or administrator) has any permission to access the file. Then reboot. After that, you can change the permissions back to give yourself permission to delete the file, then delete it.

Did you try to delete the file from Safe mode?

The Killbox program did the trick many thanks for your comments guys/girls.  I tried the Kelvir virus search from symantech but this virus was not found.  I did not have to use the safe mode as the killbox worked first time.
