What is the Full Form of VIRUS?

A computer virus is a type of malicious software (malware) designed to replicate itself and spread from one computer to another. It can attach itself to legitimate programs or files, causing harm to systems and data.

 

How Viruses Spread

• Infected Files: Viruses often spread through infected files that users download or share, such as email attachments or software installations.

• Removable Media: USB drives and external hard drives can carry viruses, transferring them to other computers when connected.

• Network Connections: Viruses can spread across networks, infecting connected devices and systems.

Types of Computer Viruses

• File Infector Viruses: These attach themselves to executable files and activate when the infected program is run.

• Macro Viruses: These target applications like Microsoft Word or Excel, exploiting macro features to spread.

• Polymorphic Viruses: These change their code or signature with each infection, making them harder to detect by antivirus software.

Impact of Viruses

• Data Loss: Viruses can corrupt or delete files, leading to significant data loss and operational disruption.

• System Performance: Infected systems may experience slow performance, crashes, or unexpected behavior.

• Security Breaches: Viruses can compromise sensitive information, leading to data theft and security breaches.

Conclusion

Understanding computer viruses is essential for protecting systems and data from potential threats. Awareness of how viruses spread and the various types can help users implement effective prevention measures, ensuring a safer computing environment.
