Computer Fundamentals (Concept of Computer related threats (virus, worms, Trojan, phishing etc.) remedies and protection)

Computer threats, also known as cybersecurity threats, are malicious software or attacks that aim to compromise or damage computer systems and networks. There are several different types of computer threats, including:

  1. Viruses: A virus is a type of malware that can replicate itself and spread from one computer to another. It is designed to damage or disrupt the operation of a computer system.

  2. Worms: A worm is a type of malware that spreads itself from one computer to another through network connections, without the need for a host file. It can replicate itself and spread rapidly, potentially causing significant damage to computer systems and networks.

  3. Trojan horses: A Trojan horse, or Trojan, is a type of malware that disguises itself as a legitimate program or file. When executed, it can perform a variety of malicious actions, such as stealing data or installing other types of malware.

  4. Ransomware: Ransomware is a type of malware that encrypts a victim's files and demands a ransom from the victim to restore access to the files.

  5. Phishing: Phishing is a type of online scam in which attackers send fraudulent emails or create fake websites that appear to be legitimate in order to trick users into disclosing sensitive information, such as passwords or financial information.

It's important to protect your computer and network from these types of threats by using antivirus software and other security measures, such as keeping your operating system and other software up to date, using strong passwords, and being cautious when opening emails or downloading files from the internet.

 

There are several steps you can take to protect your computer and network from cybersecurity threats:

  1. Install antivirus software: Antivirus software helps to detect and remove malware from your computer. It should be kept up to date to ensure that it can protect against the latest threats.

  2. Keep your operating system and software up to date: Software developers regularly release updates to fix vulnerabilities and improve security. It is important to keep your operating system and other software up to date to ensure that your computer is protected against the latest threats.

  3. Use strong passwords: Using strong, unique passwords for your accounts can help to prevent unauthorized access to your accounts and personal information.

  4. Be cautious when opening emails or downloading files: Be careful when opening emails or downloading files from the internet, as they may contain malware. Only open emails and download files from trusted sources.

  5. Enable firewalls: A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. Enabling a firewall can help to protect your computer from unauthorized access and malware.

  6. Use a virtual private network (VPN): A VPN encrypts your internet connection and can help to protect your online activity from being monitored or tracked.

By following these steps, you can help to protect your computer and network from cyber threats. It is also important to regularly back up your data to protect against data loss due to malware or other types of attacks.
