What is a potentially dangerous file?
In the realm of the computerworld there are potentially dangerous files, that means files which can do harm to your computer and harmless files. Potentially dangerous files can either execute themselves (they are programs eg with extensions *.exe, *.msi), they can be called by them (like files with the extensions *.dll) or they can call executable programs (like *.bat or *.cmd files). The files can be distinguished by looking at the file extension (on XP Operating Systems fileextensions are NOT shown by default). The file extension is the last name after the last dot, eg .exe, .doc, .jpg, .avi and thousands more. All potentially dangerous files with extensions like *.exe, *.dll, *.bat, *.msi (and dozens more) are potentially dangerous and will be blocked by FSM (in all Whitelist and Blacklist modes). Harmless (or passive) files with extensions like *.txt, *.jpg, *.avi or *.mpg (and a gazillion others) on the other hand, (under normal circumstances) can do NO harm to your computer syste
