Because the archive is the best way to transport a virus and harder to detect the virus within. I recommend that you should scan the archive before opening, most antivirus program know how to do this.

Are ogg files viruses why do they constantly multiply and how do you delete it. every time the files get deleted they just keep coming back. PLEASE HELP?
Ogg is a free, open container format maintained by the Xiph.Org Foundation. It is designed for use with streaming media. Before 2007, the .ogg filename extension was used for all files whose content used the Ogg container format. Since 2007, the Xiph.Org Foundation recommends that .ogg only be used for Ogg Vorbis audio files. The Xiph.Org Foundation decided to create a new set of file extensions and media types to describe different types of content such as .oga for audio only files, .ogv for video with or without sound (including Theora), and .ogx for multiplexed Ogg.Look to see if you also have .oga, .ogy, and/or .ogx files. If you have been running any kind of streaming media and these other file extensions are also showing up, it is a good indication that what you are seeing is just the files associated with some streaming media. That would also explain why they keep showing up again.

What is SFX Archive?
What is a SFX-archive?A SFX (SelF-eXtracting) archive is an archive merged with an executable module, which is used to extract files from the archive when executed. Thus, no external program is necessary to extract the contents of a SFX archive, it will execute itself. Nevertheless WinRAR can work with SFX archives as with any other archives, so if you do not want to run a received SFX archive (for example, because of possible viruses), you may use WinRAR to view or extract its contents.SFX archives usually have .exe extension just like any other executable file.SFX archives are convenient if you want to send an archive to somebody but do not know if they have an appropriate archiver to extract files. You may also use SFX archives to distribute your own software.For example, the WinRAR package is based on GUI RAR SFX module Default.sfx.

What is the difference between extracting files and copying them?
To understand this you must first understand a little about "COMPRESSED" files. The entire scope of the topic "COMPRESSED FILES" is beyond the scope answer but the basics are as follows...Extracting is used in conjunction with a "COMPRESSED" file. A compressed file (such as a .ZIP, .RAR, .ISO, (and many others)) is a single or group of files arranged in volumes which contain one or more computer files. The files inside the compressed file could be almost any type and are usually stored in the compressed file in order to shrink them into a single archive which is smaller than the files it contains when they are decompressed. This is quite commonly done to make transferring groups of files easier, as well as to make larger files quicker to download or upload since being smaller they do not take as long to send/receive. Two of the most common compression programs are WinZIP and WinRAR (.zip and .rar).With this in mind when you extract a file you are removing it from the archive, expanding it to its original size then copying the restored file to a specified folder. When you copy a file, you are simply duplicating a file (any file) in memory and writing an exact copy of that file to a specified folder.Note that if you have a .RAR file (e.g. file1.rar) which contains a bunch of photos you took on vacation (e.g. photo1.jpg, photo2.jpg, photo3.jpg) you could EXTRACT the file1.rar to the folder ("C:\ANYFOLDER") and that folder would contain all of the photos which were in file1.rar. However if you simply COPY file1.rar to "C:\ANYFOLDER" folder, the folder will contain the file 'file1.rar'. You would still have to extract the photos from it should you wish to access them.
