a virus
A destructive program that spreads from computer to computer is called a "virus." Viruses attach themselves to legitimate programs or files and can replicate themselves to infect other systems. They often cause harm by corrupting or deleting data, slowing down system performance, or even compromising security. Other similar types of malicious software include worms and Trojans, but viruses specifically require a host program to propagate.
A virus is a piece of a program that attaches itself to other programs. In contrast, a worm is a full program that spreads itself, and a trojan is a harmful program that passes itself off as, and in some cases might also be, as useful program.
An application program virus is a type of malicious software that infects executable files or applications on a computer system. It attaches itself to legitimate programs and can spread when the infected application is run, potentially causing damage to files, stealing data, or enabling unauthorized access. Unlike other types of viruses, application program viruses specifically target software applications rather than system files or the operating system. Prevention typically involves using antivirus software and practicing safe computing habits.

In computer security terminology, a virus is a piece of program code that, like a biological virus, makes copies of itself and spreads by attaching itself to a host, often damaging the host in the process. A pattern is a virus that would happen over and over.
a worm is a malicious computer program. its almost like a virus, but it spreads. as an example some worms know when your sending an email, and puts a copy of itself into the email, thus infecting the receiver. a worm reducer is like an anti virus, but for worms.
A computer virus is a piece of self-replicating code that attaches itself to other programs and files. Its main goal is to spread but it will often have a payload which may damage the host computer by deleting files, corrupting files, modifying configurations, or formatting the hard disk.

It starts out affecting everything around the file it comes in, such as disabling, damaging, even deleting files, then it spreads to neighboring files in the process, and eventually consumes the whole computer to the point where the computer can no longer function.
A program that instructs a computer to perform annoying or destructive actions is commonly referred to as malware. This includes various types such as viruses, worms, and ransomware, which can disrupt system operations, steal data, or cause damage. Malware often spreads through infected files or links, targeting vulnerabilities in software or user behavior. It's essential to use antivirus software and practice safe browsing habits to protect against such threats.
