Computer Viruses

What Are Computer Viruses?

Computer Viruses are malicious software programs that can infect and replicate themselves on a computer. They are designed to compromise system security and perform harmful actions on the infected system.

How Do They Work?

Computer viruses typically attach themselves to legitimate files or programs. When a user runs the infected file or program, the virus executes, and it can carry out various malicious activities, such as:

Data Corruption: Viruses can corrupt or delete files.
Unauthorised Access: Some viruses provide backdoor access for attackers.
Data Theft: Viruses can steal sensitive information.
Spreading: Viruses can replicate and spread to other systems.

Why are they dangerous?

Computer viruses are dangerous due to their ability to compromise system integrity:

Data Loss: Viruses can lead to data loss or corruption.
System Compromise: Attackers can gain control over infected systems.
Propagation: Viruses can spread to other systems, creating a broader security risk.

How to Prevent Computer Viruses?

Preventing computer viruses involves:

Antivirus Software: Use reputable antivirus and anti-malware software.
Regular Updates: Keep operating systems and software up to date with security patches.
Email Vigilance: Be cautious when opening email attachments from unknown sources.
User Education: Educate users about the risks of downloading and executing unknown files.
Safe Browsing Practices: Avoid downloading software or files from untrusted websites.
