Answer 2

1. A computer virus is a type of malicious software program designed to replicate itself and spread from one computer to another. It attaches itself to legitimate files or programs and can execute harmful actions without the knowledge or consent of the user.

2. How a computer virus works can vary depending on its specific design, but the general process typically involves the following steps: a. Injection: The virus gains entry to a computer system, usually through infected files, email attachments, or malicious websites. b. Replication: Once inside, the virus tries to replicate itself by creating copies of its code and attaching them to other files or programs on the same computer or across a network. c. Propagation: The virus spreads to other computers by various means, such as email attachments, removable storage devices, or network connections. d. Activation: At a predetermined time or under specific conditions, the virus may become active and execute its intended harmful actions, which can range from data corruption and deletion to stealing sensitive information or disrupting system functionality.

3. To prevent computer infections, there are several essential measures you can take: a. Install Antivirus Software: Use reputable antivirus software that can detect and remove viruses and other malware. b. Keep Software Updated: Regularly update your operating system, web browsers, and other software to patch security vulnerabilities that could be exploited by viruses. c. Exercise Caution Online: Avoid clicking on suspicious links, downloading files from untrusted sources, or opening attachments from unknown senders. d. Use Strong Passwords: Use complex passwords and enable two-factor authentication (2FA) when possible to secure your accounts. e. Backup Regularly: Create backups of your important data and store them separately from your computer to protect against data loss due to viruses.

4. Yes, maintaining up-to-date virus protection is crucial for staying protected against the latest threats. As new viruses and malware are constantly being developed, antivirus software providers regularly release updates and patches to detect and counter these threats effectively. Ensuring your virus protection is updated helps to ensure you have the latest security measures in place to safeguard your computer and data. Most modern antivirus software can be set to update automatically, providing ongoing protection without requiring manual intervention.
