I was wondering if this folder and file have anything to do with Norton Power Eraser? Can I safely delete the folder? I have found this page (http://file.org/extension/etl), which talks about the .etl file extension, although I have no idea what it is. Thanks in advance.
It didn't take up much space, but I deleted it anyways. No problems at all so far.
This seems to be a log file from your having run Norton Power Eraser, NPE. It may contain the information necessary if you need to reverse any fixes you allowed NPE to make.
If your system has no problems after running NPE, you can try deleting the file. If it is not really taking much room, I would probably be inclined to leave it. Just in case your system acts up again that could be related to the last run of NPE.
