Viruses - A virus is a small piece of software that piggybacks on real programs. For example, a virus might attach itself to a program such as a spreadsheet program. Each time the spreadsheet program runs, the virus runs, too, and it has the chance to reproduce (by attaching to other programs) or wreak havoc. \n\nTrojan horses - A Trojan horse is simply a computer program. The program claims to do one thing (it may claim to be a game) but instead does damage when you run it (it may erase your hard disk). Trojan horses have no way to replicate automatically. \nA destructive program that masquerades as a benign application. Unlike viruses, Trojan horses do not replicate themselves but they can be just as destructive. One of the most insidious types of Trojan horse is a program that claims to rid your computer of viruses but instead introduces viruses onto your computer. \nThe term comes from the a Greek story of the Trojan War, in which the Greeks give a giant wooden horse to their foes, the Trojans, ostensibly as a peace offering. But after the Trojans drag the horse inside their city walls, Greek soldiers sneak out of the horse's hollow belly and open the city gates, allowing their compatriots to pour in and capture Troy. \n\n\nTrojan horses are broken down in classification based on how they breach systems and the damage they cause. The seven main types of Trojan horses are:\n\nRemote Access Trojans \nData Sending Trojans \nDestructive Trojans \nProxy Trojans \nFTP Trojans \nsecurity software disabler Trojans \ndenial-of-service attack (DoS) Trojans

Haahahah...How can computer virus affect human health.The only thing it can do is make u feel irritated.

each virus is different, so you'd need to know which one it was...or know in-depth how your os works (and that is a book, not a post at yahoo answers)

The answers to these questions would be specific to whatever virus you are interested in looking at. Some viruses can be cultured, some cannot. Immunofluorescence requires that you have an antibody that is specific for the virus you are trying to detect

A virus is neither a plant nor an animal. It acts like a living organism when inside the body of a host, but behaves like a non living thing when outside of it! Hence viruses are able to exist for thousands of years...\nBacteria on other hand, is a living being and hence is mortal too.

Good and bad only exists in human mind. Spread of a virus is good for that virus, and for whatever thing that fish ate. It also helps that one little & weak fish that just happened to have natural resistance to the virus - it would re-populate the pond with it's offspring.\n\nNature is about balance of many things that fight for their own survival against everybody else. If the balance gets upset by some force, some species benefit from it, and some loose.

Viruses are in a nether world. They are neither dead nor alive, and they certainly don't belong to a phylum or a class.

A dangerous computer program with the characteristic feature of being able to generate copies of itself, and thereby spreading. Additionally most computer viruses have a destructive payload that is activated under certain conditions.\n\nA computer virus is a self-replicating program containing code that explicitly copies itself and can "infect" other programs by modifying them or their environment such that a call to an infected program implies a call to a (possibly evolved) copy of the virus

You can find some excellent information and pictures at:\nhttp://www.virology.net/Big_Virology/BVDNAmyo.html\n\nor if you are looking for higher level information you can find a good paper at http://www.pubmedcentral.gov/articlerender.fcgi?tool=pubmed&pubmedid=12626685\n\nwww.pubmed.com is a great source for any scholastic/scientific information.  You can read all of the latest research that has been published in peer reviewed journals there.  Its worth the time to learn how to use it.

Almost certainly a virus.  DO NOT OPEN IT.\n\n.cmd files are batch files that contain a variety of commands that can be used to do many things.  if you want to see what it is, open it on a computer that runs Macintosh operating systems or Linux... DO NOT OPEN ON WINDOWS.

You CANNOT get viruses from media files. You are only at risk when code is actually run from a program. But you can from programs that are supposed to run or download them, like file sharing apps or ActiveX controls.

Actually I don't understand these terms. Could you please tell what is really happening in your computer? (like, a program's not opening, windows can't let you in, etc.)\n\nBut usually the source of problem in a computer is a virus. So go get a cleaner.

A virus (Latin, poison) is a microscopic, filter passing micro-organism, parasitic within living cells, and of which many forms cause disease in human beings.\nBacteria (singular: bacterium)- A group of micro-organisms, also called 'schizomycetes'. They are typically small cells of about 1 micron in transverse diameter. Structurally they are a protoplast, containing cytoplasmic and nuclear material (not seen by ordinary methods of microscopy) within a limiting cytoplasmic membrane, and a supporting cell wall. Other structures such as flagella, fimbriae and capsules may also be present. Individual cells may be spherical, straight or curved rods, or spirals; they may form chains or masses, and some show branching with mycelium formation. They may produce various pigments including chlorophyll. Some form endospores. Reproduction is chiefly by simple binary fission. They may be free living, saprophytic or parasitic; some are pathogenic to man, animals and plants.\nPlease see the webpages for more details on Virus and Bacteria.

I don't ahve official info, but I do know alot out viruses.  You can't recieve a virus through a gif.  The gif is just a format and if you open it it will just view the image.  It is posible that the virus was .exe and renamed to .gif, but even then when u open it with a program that normaly opens gifs it won't properly open thy virus.  So don't worry, open as many gifs as you want.  :)

Another part of virus protection (and maybe the most important one) is the so-called resident protection (also known as on-access protection). Simply said, it is a program that continuously monitors the entire computer (the operating system and all running programs) and watches for suspicious activities (e.g. execution of a virus), thus avoiding/preventing a virus from damaging files on your computer.\n\n \n\nFrom the very definition of the resident protection, it is clear that most of the time it doesn't require any special care from your side. You don't have to execute it (it activates automatically when you start your computer) and if everything is OK, you won't even notice it is running. Its presence in the system is indicated by a small icon with the avast! symbol (lowercase 'a' in a ball) in the notification area (next to the clock). The second avast! icon, related to VRDB functions (see the help for more information), is also displayed here - as a lowercase 'i' in a ball. These two icons can be co-joined into one should the user feel the need to do so.\n\n \n\nSometimes, it may be practical to either pause the resident task, or maybe change its sensitivity. To do this, you can use the tiny resident control in the avast! simple user interface, by clicking the icon with the resident protection symbol - lowercase 'a'.\n\n \n\nMore detailed settings can be accessed by double-clicking the avast! taskbar icon.

Viruses enter your body from other bodily fluids, whether it be blood or saliva, excrement or vomit.  Viruses generally travel easier in the medium they affect, AIDS is blood-borne, and while it's possible a blood to blood transfer would infect you with a common cold or flu, it's generally spread by saliva. Generally viruses cannot survive for long outside of a host organism.\n\nYour body is under attack by viruses constantly, many times you will receive a virus and not even know because your body is able to fight it off before it can affect you. Besides the obvious, visible or physical symptoms of an infection, a doctor can test for anti-bodies to see if you've been infected. The main reason we give vaccinations is so your body can fight off a weakened or dead virus and learn to make the anti-bodies to defeat it for the next time you are infected by it. However some viruses can remain dormant for long periods of time and even tests cannot show their presence, since the viral load (amount of virus particles) is so low.  \n\nOn a side note, contrary to what was said above virus are NOT organisms. By the definitions of life it is not alive, technically it is an obligate intracellular parasite. This is for a few reasons, but the big ones are that they are not cellular based and they cannot reproduce (by themselves). They do share characteristics with living things, such as the use of DNA/RNA and the ability to evolve.
