What is the most widespread medium for computer viruses?

The six characteristics of computer viruses are: 1. Parasitism; computer viruses are parasitic in other programs. When this program is executed, the virus will cause damage. 2. Destructive. 3. Infectiousness. 4. Latent nature; some viruses are like time bombs, with the timing of their attack being pre-designed. 5. Concealment. 6. Enforceability.

A computer virus is a program that attaches itself to a host computer with the intent of further multiplying and spreading. From individuals to large organizations, anyone with the right skills can create a computer virus and infect computers, smartphones, tablets, and even smart cars.

Yes, Code Red is a computer virus. It is a network worm that specifically infects computers running Microsoft IIS web servers. This virus was discovered on July 15, 2001, hence the name "Code Red".

Classification of computer viruses: 1. According to the type of media they are attached to, they can be divided into three categories: network viruses, file viruses and boot viruses; 2. According to computer-specific algorithms, they can be divided into three categories: incidental viruses, worm viruses and variable viruses. kind. Network viruses are computer viruses that infect executable files through a computer network. File viruses are viruses that attack files on your computer. A boot virus is a virus that mainly infects drive sectors and boot sectors of hard disk systems.

The harm of computer viruses is manifested by affecting the execution of programs and destroying user data and programs. The main specific harms are: 1. The virus triggers direct damage to computer data and information; 2. Occupies disk space and destroys information; 3. Seize system resources; 4. Affect computer running speed; 5. Computer virus errors and unforeseen harm; 6. Computer virus compatibility affects system operation, often leading to crashes; 7. Computer viruses cause serious psychological pressure to users .

A computer virus is an instruction or program code that is inserted into a computer system or computer level to damage data, affect the use of the computer, and cannot replicate itself. Computer viruses are different from medical viruses. They do not occur naturally but are created by people using vulnerabilities or vulnerabilities in computer hardware or software to compile instructions and program codes, and then lurk in the computer media through some means. When encountered Certain conditions will be activated and copied by other programs or naturally evolved into certain programs to achieve the purpose of infecting the program and destroying computing resources.

Computer virus is a kind of malicious software with seven characteristics: "self-replication", "latency", "destruction", "concealment", "diverse transmission methods", "stealing information" and "remote control": 1 . Computer viruses can automatically copy themselves and spread to other files, systems or computers; 2. Computer viruses usually lurk in the system after infection, hiding their existence and waiting for specific conditions to trigger; 3. The main goals of computer viruses It destroys or damages computer systems, files and data; 4. Computer viruses will hide in the core part of the system, etc.

The main targets of computer virus damage are "programs and data". A computer virus refers to a set of computer instructions or program codes compiled or inserted into a computer program that destroy computer functions or data, affect computer use, and are capable of self-replication.
