Characteristics of computer viruses

Computer virus is a kind of malware with the characteristics of "self-replication", "latency", "destruction", "concealment", "diverse ways of spreading", "stealing information" and "remote control" "Seven characteristics: 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 the trigger of specific conditions; 3. , The main goal of computer viruses is to destroy or damage computer systems, files and data; 4. Computer viruses will hide in the core part of the system, etc.

Computer viruses are a type of malware that have the following characteristics:

1. Self-replicating: Computer viruses can automatically Copy itself and spread to other files, systems or computers. They can be transmitted via network connections, removable devices, email attachments, etc.

2. Latency: Computer viruses usually lurk in the system after infection, hiding their existence and waiting for specific conditions to trigger. This allows them to exist unnoticed for long periods of time.

3. Destructive: The main goal of computer viruses is to destroy or damage computer systems, files and data. They can delete, modify or encrypt files, damage hardware, or even cause system crashes.

4. Stealth: In order to avoid detection and removal, computer viruses usually hide in core parts of the system or in harmless files. Some viruses also use encryption, compression, or deformation techniques to evade detection by protection software.

5. Diverse ways of spreading: Computer viruses can spread in a variety of ways, including through network downloads, shared files, infecting removable devices (such as USB flash drives), and through email attachments. .

6. Steal information: Some computer viruses are designed to steal users’ personal information, passwords, bank account numbers and other sensitive data and send it to attackers. This can lead to identity theft and financial loss.

7. Remote control: Some advanced computer viruses have remote control capabilities, allowing attackers to remotely access the infected computer to perform malicious operations, surveillance activities, or other illegal activities.

In order to protect computers from viruses, users should install reliable anti-virus software, regularly update system and software patches, be wary of files and links from unknown sources, and avoid downloading unverified software, and preventive measures such as backing up important data.
