A computer virus is nothing more than a computer program. Same with Worms and Trojan Horse Programs. They're just code written by a person (or people, as the case may be.) Fro…m the McAfee Security home page: "Virus - A computer program file capable of attaching to disks or other files and replicating itself repeatedly, typically without user knowledge or permission. Some viruses attach to files so when the infected file executes, the virus also executes. Other viruses sit in a computer's memory and infect files as the computer opens, modifies or creates the files. Some viruses display symptoms, and some viruses damage files and computer systems, but neither symptoms nor damage is essential in the definition of a virus; a non-damaging virus is still a virus." ALSO: "Worm - Worms are parasitic computer programs that replicate, but unlike viruses, do not infect other computer program files. Worms can create copies on the same computer, or can send the copies to other computers via a network. Worms often spread via IRC (Internet Relay Chat). " AND: "Trojan Horse - A Trojan horse program is a malicious program that pretends to be a benign application; a Trojan horse program purposefully does something the user does not expect. Trojans are not viruses since they do not replicate, but Trojan horse programs can be just as destructive." To answer your question, No, and sort of yes. There are some viruses that modify themselves slightly during replication, and therefore become products of their own evolution, but even these were specifically written to do so by a human being.
By learning a programming language. C and C++ are usually the ones used in viruses, but this is only true because these languages are very modular and functional, which means …they have a lot of functions in them. This makes it really easy to "tell" the virus EXACTLY what you want to do. It is very easy write a virus in this language. Viruses are made as to change your hard drive data, use lots of CPU processing space (to slow your computer like mad), and to change data around to corrupt your computer. How do you do this; I don't know (I don't know C or C++) In Batch, it is fairly easy to write a virus, as it is pretty easy to use cmd in Windows. You just have to know where windows is stored in. Then you can just find the path to it, then you can tell your Batch virus to delete certain files. I'm not going to tell you how, because that's illegal to do so here. That's pretty much all there is to making computer viruses. Basically, all programming languages can be used to write viruses.
i believe they mean in vitro or in vivo, bcuz the book said they cant be made unless in host. so then it refers to in vivo and vitro
protein, nucleic acid /\\ All viruses are made up of a core of genetic material ... nucleic acid, which is either DNA or RNA. This is surrounded by a protein coat.
Cause some greedy people want to steel personal info like credit card numbers Source: technibble.com and my opinion and what I've herd.
Viruses are made by tiny micro organism( germs) that basically float in the air or surround you. You can get it from people sneezing or being by an sick person/ etc.
What Are Viruses Made Of? SORRY WE DONT KNOW THIS ANSWER HAHa SAMMIE IS THE BESt xccv cb bcz
Viruses are not bacteria or fungi. These are completely different.
The inner core of a virus is made up of genetic material that contains directions for creating new viruses.
Viruses are mainly DNA. They cannot reproduce themselves without invading a living cell and using its "machinery" to create copies. This is why they cause diseases.
Viruses weren't so much made as evolved from complex molecules, they are probably the simplest form of life. (in some cases they aren't even classified as alive) Unless you'r…e referring to computer virii, in which case they were originally written for fun, just do do funny stuff to computers, like pop up messages on the screen on April fools day, for example. Later on criminals and other wrong-doers decided that viruses were the perfect way to disrupt computer users, and in some cases exploit money from people.
The most basic viruses are composed of either RNA or DNA and are surrounded by a layer of protein subunits. Some viruses have a viral envelope that serves to protect the virus… from the immune system and helps with adhesion of a virus to other things. The complex viruses consist of an icosahedral head attached to a helical tail often attached to protein fibers that can look like 'legs'.
i think it come frome it that fertiltion
No, antibiotics are made a microorganism that is antagonistic to the growth of other microorganisms in high dilution.
