Top 10 Proven Ways to Secure a Computer Network From Malware

Last updated: January 29, 2024


Phishing schemes, viruses, worms, ransomware, and spyware represent just a few of the tactics used by threat actors (hackers) to compromise computers and networks, leading to potential financial harm for both individuals and companies. The ease with which one’s identity can be stolen, simply by clicking a malicious link in an email, can be a daunting realization.

However, it is important to remember that there are numerous measures to secure a computer network from malware. We will be more concerned with the ways of computer network protection using tools that are available to all users. Let’s leave complex protection systems to professionals.

How to prevent malware and viruses?

1. Use strong passwords

Creating a strong computer password or phrase is widely considered one of the easiest and most effective strategies to enhance system security. It is recommended to set up a complex password or phrase consisting of 8 to 64 alphanumeric characters, and to include special characters such as “#@*&.” It is important to remember that passwords should never be written down or stored in close proximity to the device. Whenever possible, adopting a two-factor authentication strategy is highly recommended.

2. Use a firewall

Windows and macOS both come equipped with built-in firewalls. These firewalls act as software barriers that shield your information from external threats. Their primary role is to prevent unauthorized access to your business network while providing alerts for any potential intrusion attempts. Before connecting to the internet, it is crucial to ensure that the firewall is enabled. Additionally, you have the option to purchase a hardware firewall from reputable companies such as Cisco, Sophos, or Fortinet. These hardware firewalls are compatible with your broadband router and provide added protection to your network as they also contain built-in firewalls. For larger businesses, the option to purchase an additional business networking firewall is available.

3. Install VPN

Anyone who will use VPN for Mac will be able to significantly reduce the risk of viruses infecting the system. If you do no download VPN, then you are susceptible to phishing, DDoS attacks, viruses, data interception, etc. Advanced VPNs such as VeePN not only protect networks from these vulnerabilities but also allow access to any content. Given the availability of free trial versions, this is an additional argument to try VeePN.

4. Create a system backup

Many different types of malicious agents have the capability to destroy the contents stored within a computer. To ensure the recoverability of data in the event of any harmful incidents, it is advised to establish a regular backup schedule.

There are various backup options available, such as utilizing a cloud service or employing a personal external hard drive. A cloud service provides the means to back up data online, while a personal external hard drive can be connected to the computer for manually copying updated files.

5. Keep your OS, apps, and browser updated

Installing operating system updates is always recommended to ensure the security and performance of your device. These updates often include important security fixes that protect against potential hackers who may attempt to access and exploit your data. The same applies to apps – keeping them up to date is crucial.

6. Use email with caution

Hackers possess a range of techniques for exploiting email, including concealing viruses within attachments. It is advised that users refrain from opening or reading emails from unfamiliar email addresses. Swift removal of such emails from the inbox is necessary to ensure the safety and security of the user.

7. Ignore spam

Caution should be exercised when dealing with email messages from unfamiliar sources, and refraining from clicking on any accompanying links or opening attachments is recommended. While inbox spam filters effectively identify obvious spam, it is crucial to remain vigilant for more advanced phishing emails that imitate known contacts or trusted establishments like banks. Maintaining awareness and being cautious of any suspicious-looking or sounding content is advisable.

8. Use virtualization

Not everyone needs to take this route. However, if one visits sketchy websites, one should expect to be bombarded with spyware and viruses. The optimal way to avoid browser-derived intrusions is by steering clear of unsafe sites. However, virtualization provides an alternative solution by allowing users to run their browsers in a virtual environment, such as Parallels or VMware Fusion. This approach sidesteps the operating system, enhancing security measures.

9. Use two-factor authentication

Passwords serve as the initial barrier against computer hackers. Nevertheless, an additional layer enhances security. Numerous websites offer the option to enable two-factor authentication, which enhances protection by requiring users to enter a numeric code, sent to their phone or email address, in conjunction with their password during the login process.

10. Don’t use unsecured public Wi-Fi

Unsecured Wi-Fi poses a significant cybersecurity risk when individuals travel for business or work remotely. Public Wi-Fi networks without passwords, which are commonly used, lack essential security features. consequently, these networks become prime targets for hackers seeking unauthorized access. But you can also use a VPN, which encrypts all your data and keeps you safe even when using public networks. The added benefit of unblocking Hulu VPN will also come in handy. With a VPN, neither your ISP nor the owner of the Wi-Fi network will know what you are doing on the Internet.


The adoption of proper cyber security measures is essential in the current digital landscape. Many threats are lurking online, and if one does not take appropriate safety measures, even a minor slip-up can lead to devastating consequences. Utilizing the information provided within this list helps ensure that your computer remains secure from potential hackers. It is recommended to persistently review and adjust these approaches.
