In DOS systems, a file with a.BAK extension, indicating that the file is a backup. Many applications produce BAK files as part of their autosave procedure. Periodically, you may want to search for BAK files and delete old ones.
I happened accross a notepad file called Trojan.BAK. The contents look like gobble-d-****. Does this sound like something that should be on my computer? I am running Windows ME and NAV/S&D report no problems.
