If none of that works, try letting Windows fix itself:
Double Click My Computer
Right click on Drive C:
Select Properties
Select Tools
Under Error Checking Select Check Now
Check Automatically Fix File System Errors
Reboot when prompted.
This can fix a lot of misnamed/zero byte files because Windows takes a look at it and decides "I can't work with that!" and changes the file accordingly.
If that doesn't work, or Windows burps on the filechecking you can try this:
Download Total Commander (free) from
http://www.ghisler.com/download.htm.
Restart the computer
Hold F8 during restart until start menu appears
Choose Safe Mode
Enter the Admin's Account (not always necessary)
Explore the Recycle Bin with Total Commander, usually C:\Recycler
Mark the file with Right Click
Press F8
Confirm deletion
Reboot.
Let us know how it goes!
