Righ-click the file and choose properties and see if it's got any affiliation listed there.
Otherwise - try deleting it this way (or renaming it with REN)
Don't think it's affecting you though...

>>
Open a Command Prompt window and leave it open. Close all open programs. Click Start, Run and enter TASKMGR.EXE Go to the Processes tab and End Process on Explorer.exe. Leave Task Manager open. Go back to the Command Prompt window and change to the directory the undeletable file is located in. At the command prompt type DEL where is the file you wish to delete. Go back to Task Manager, click File, New Task and enter EXPLORER.EXE to restart the GUI shell. Close Task Manager.

Can't delete file or folder:

With which ever one you use Put it in your Windows or Windows\System32 folder

Then
start > run cmd

then do this
RKILL an3api.dll

or

now locate where the file is and delete it

Perfect !!!!!  :)

u shud try Sirbounty's suggestion if u are getting a "File is being in Used" error while trying to delete the above file,,,,
but if u are getting a "Access Is Denied" error, then u shud try to take the ownership of the file :)

then do this
RKILL an3api.dll


that should be
then do this
PSKILL an3api.dll

or

Ok I think what has happened is that the hacker has added a character to the end of the folder that Explorer does not recognize.

Try this open a command window and do this

Open a CMD.EXE window.
CD to the top of the mess.
Use: DIR /X /A   to see the SHORT FILE NAMES of the files and directories there.
Use a combination of CD, RD, and DEL and the SHORT FILES names reported with DIR /X to delete your way to the bottom and then back up the tree removing the files on the way down and the directories on the way up.
Most likely there is NOT a protection issue here so you shouldn't need worry about ownership or file protections.

RMDIR [/S] [/Q] [drive:]path
RD [/S] [/Q] [drive:]path

   /S      Removes all directories and files in the specified directory
           in addition to the directory itself.  Used to remove a directory
           tree.

   /Q      Quiet mode, do not ask if ok to remove a directory tree with /S

SUMMARY
Because applications control the policy for creating files in Windows, files sometimes are created with illegal or reserved names, such as LPT1 or PRN. This article explains how to delete such files using the standard user interface.

MORE INFORMATION
NOTE : You must be logged on locally to the Windows computer to delete these files.

If the file was created on a file allocation table (FAT) partition, you may be able to delete it under MS-DOS using standard command line utilities (such as DEL) with wildcards. For example:

DEL PR?.*

-or-

DEL LPT?.*

These commands do not work on an NTFS partition as NTFS supports the POSIX subsystem and filenames such as PRN are legal under this subsystem. However, the operating system assumes the application that created them can also delete them; therefore, you can use commands native to the POSIX subsystem.

You can delete (unlink) these files using a simple, native POSIX application. For example, the Windows Resource Kit includes such a tool, Rm.exe.

NOTE : POSIX commands are case sensitive. Drives and folders are referenced differently than in MS-DOS. Windows 2000 and later POSIX commands must use the following usage syntax:
posix /c <path\command> [<args>] IE: posix /c c:\rm.exe -d AUX.

Usage assumes Rm.exe is either in the path, or the current folder:
rm -d // driveletter / path using forward slashes / filename
For example, to remove a file or folder named COM1 (located at C:\Program Files\Subdir in this example), type the following command:
rm -d "//C/Program Files/Subdir/COM1"
To remove a folder and its entire contents (C:\Program Files\BadFolder in this example), type the following command:
rm -r "//C/Program Files/BadFolder"
Another option is to use a syntax that bypasses the normal reserve-word checks altogether. For example, you can possibly delete any file with a command such as:
DEL \\.\ driveletter :\ path \ filename
For example:

DEL \\.\c:\somedir\aux

Thank you all for your quick responses.  I tried your suggestions, but was not able to resolve the problem.

Just yesterday I found the following link

http://forums.techguy.org/t236525.html

Which explained the use of VX2 Finder to remove the file.  I have asked the moderator to refund my points, but thanks again for your suggestions.
