- By clearing cookies frequently, you can reduce the risk of unauthorized access to your data and prevent targeted advertising.

Keep the operating system and software applications up to date:
- Regularly updating your operating system and software applications is crucial for computer security.
- Updates often include security patches that fix vulnerabilities and protect against new threats.
- Hackers are constantly finding new ways to exploit weaknesses in software, and updates help to close those vulnerabilities.
- Neglecting updates can leave your computer open to attacks and increase the risk of malware infections.
- Enable automatic updates whenever possible to ensure that you always have the latest security patches installed.

Install firewalls:
- Firewalls act as a barrier between your computer and the internet, monitoring and controlling incoming and outgoing network traffic.
- They help to prevent unauthorized access to your computer and protect against malicious activities.
- Firewalls can be hardware-based or software-based, and it is recommended to have both for comprehensive protection.
- Hardware firewalls are typically found in routers and provide network-wide protection, while software firewalls are installed on individual computers.
- Firewalls analyze network traffic, block suspicious connections, and allow you to define rules for specific applications or services.

All of the above:
- The correct answer is option 'D' because all the mentioned practices are essential for computer security.
- Clearing browser cookies frequently helps to protect your privacy and prevent unauthorized tracking.
- Keeping the operating system and software applications up to date ensures that you have the latest security patches and fixes for vulnerabilities.
- Installing firewalls provides an additional layer of protection by monitoring and controlling network traffic.
- By following all these practices, you can significantly enhance your computer security and reduce the risk of cyber threats.
