I just got three e-mails telling me to search for, and delete, an alleged virus called SULFNBK.EXE. Fortunately, I don't believe anything I read in an e-mail from somebody I don't know.

If you get one of these... Don't do it. It's a Windows file that helps the system manage long file names (hence the LFN in the file name). You need it. Here are the full details from McAfee.

As you were.
