Computer interface with various developed programs and most would have an assigned file name extension tagged to it. There are the usual files that would have a doc, xls, ppt, jpg and bmp file extensions. There are also the compressed files such as zip and amr. The compressed files offer some potential risk since they are usually zipped to group files into one manageable file. Program scripts and installation software are the common contents of these zipped folders to save on space and to make it easier for distribution and transfer.
It is best to proceed with caution before totally unzipping the contents to any directory of your computer. It is the executable files such as the setup.exe that may garner much doubt. Once executable files are double clicked, it will immediate process and try to install itself on the machine. Once finished, there is no telling what effects it may do or create, thus the need for people to think twice before clicking on the files.
