That looks like a filename taken from a warning or error message. The file itself is a McAfee file -

SystemLookup - mfenlfk.png

- and there are a couple of threads on this forum about it. Look HERE and HERE and see if they provide the answer to whatever problem you've got.

Hi marcefay,

If I understand right, that s a file that is detected while you try to download the purchased programs ???  Please provide us with some more information regarding your PC

What operating system ? Windows XP/Vista/7

Did you previously have a McAfee subscription on this PC ?

Please run the MCPR tool from here  and restart the PC

Run the McPreinstall tool from here:

Logon to and reinstall the programs .
