I believe the question you are asking is "What is the part of a computer virus that does damage known as?" since the entire virus is an executable. This part is known as the payload.
Having virus protection installed on your computer is a good place to start. Watching what websites you are on and what you are downloading is major part as well.
You usually become part of a botnet by a virus infected program/game.
In most cases, viruses are attached to executable files. Sometimes they may be attached to other executable formats such as DLLs and overlays. Or they will be attached to a drive's MBR. That is the Master Boot Record and that does contain executable code at the end of a disk parameter table. The point is, the code has to be executed in order to cause an infection.For the most part, media files cannot get infected, and if there is virus code in them, the player or viewer will consider the files corrupted and either try to play/display the corruption anyway or abort with an error. There are a few exceptions such as the few media files that allow executable code or scripts to be attached.
I've never heard of a computer part named birthday. There is a type of virus attack called a birthday attack.
Your computer will be the safest around if you use McAfee virus protection. However, in order to maintain that high level of protection you will have to update your computer frequently so that you can protect it against the latest viruses. Your computer will be just as safe with any anti-virus software. What makes your computer safe is your attention to keeping the virus definitions up to date. That is the most critical part of any anti-virus software.
short answer: executable code is a program that is ready to be used write now. long answer: writing a computer program is generally a 2 part process (there are exceptions): 1) programmer writes the code 2) programmer runs his code through a special program called a Compiler the Compiler is responsible for taking code that a programmer can understand, and turning it into something that a computer can understand. executable code is (usually) code that has been compiled.
Most computer viruses are completely unique. They are created by many different individuals so their code is radically different in most cases. There are a few similarities on occasion but for the most part they are all different.
By definition, a computer virus must transmit and be self-replicating. There is no requirement for a payload. So the way to do this is to either find an existing flaw or exploit in the front end of an operating system and allows you to insert code instead of date, and then have the target machine execute the code, or to use a form of social engineering to insert the code into the user's machine, or simply insert the code as you would any other executable process. Note that not all viruses are bad. The purpose and the payload are not part of the definition.
A computer virus is a computer program that can copy itself and infect a computer without the permission or knowledge of the owner. The term "virus" is also commonly but erroneously used to refer to other types of malware, adware, and spyware programs that do not have the reproductive ability. A true virus can only spread from one computer to another (in some form of executable code) when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD, or USB drive. Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer.[1][2] In order to replicate itself, a virus must be permitted to execute code and write to memory. For this reason, many viruses attach themselves to executable files that may be part of legitimate programs. If a user attempts to launch an infected program, the virus' code may be executed simultaneously. Viruses can be divided into two types based on their behavior when they are executed. Nonresident viruses immediately search for other hosts that can be infected, infect those targets, and finally transfer control to the application program they infected. Resident viruses do not search for hosts when they are started. Instead, a resident virus loads itself into memory on execution and transfers control to the host program. The virus stays active in the background and infects new hosts when those files are accessed by other programs or the operating system itself. http://en.wikipedia.org/wiki/Computer_virus#Infection_strategies
Executable files, data and program resource files are added to the system, configuration files (or registry files) are updated.
HIV is a deaiese and it is deadly.You gat HIV or AIDS by having many sexual contact and taking drugs through needles. If you get it while you are pregnant you can pass it on to your child.
It is part of your anti virus and may use the internet to scan your computer for malicious files and/or spyware. Scans can also show files that seem suspicious to the anti-virus!
