1. Use genuine software

Due to the high cost of using genuine software, most companies will choose to use pirated software, but these pirated software may contain malware and viruses. The code they copy from genuine software will also have loopholes, allowing criminals to easily crack the security license of pirated software, steal data, implant viruses, and eventually paralyze the entire system.

2. Update the operating system regularly

The operating system manages the hardware and software resources of the computer system. Once infected with a virus, the system will crash. To combat the ever-evolving viruses, developers have built in anti-virus software, so by regularly updating the operating system, viruses can be kept away.

3. Install anti-virus software

Anti-virus software can not only resist and prevent Trojans, viruses and other threats, but also allows us to quickly manage software and avoid the trouble of rogue plug-ins.

And antivirus software is updated frequently by developers who study the behavior of each new virus and update antivirus software to combat it.

4. Scan your computer frequently

Most antivirus applications run automatically in the background and can protect against any attacks. Some attacks may not initially appear as viruses and can escape antivirus software. They can be detected if you scan your computers frequently to keep them clean and safe.

5. Connect to a secure network

Computer viruses not only exist in the system, but also in the network. If you use an unsecured network, hackers can easily access your computer from anywhere through network vulnerabilities and steal your data. For your safety, always connect via SSL or TLS to make it more difficult for others to access you. system.

6. Uninstall unused programs and files

When the virus enters the computer, it will not launch an attack immediately, but will wait for the right time to execute the appropriate file or program. They attack again. If you have too many unused files and programs on your computer, you can create a better environment for viruses to execute themselves. Therefore, we need to remove it, or uninstall it completely, not just disable it.

7. Use complex passwords

Viruses not only attack the system, they also turn into malware to steal users' passwords and destroy computer data. When setting passwords for devices, we must abandon simple passwords that are easy to guess or crack, and create complex passwords to make it more difficult for hackers to crack, thereby protecting the computer.

8. File Backup

Even if a user has taken all necessary precautions, sometimes certain viruses are too powerful and can defeat protective applications. To avoid losing data, users should create a backup system to store important files and data. You can use external disks, such as memory cards, hard disks, U disks, network disks, etc.

9. Do not open suspicious links

Hackers will launch attacks by sending suspicious links, and the websites in the links will install viruses on your computer. Once logged into these phishing URLs, hackers can steal your passwords and important data. If you're not sure where the link comes from, don't rush to open it.

10. Know when a threat is present

The most important thing is to know the symptoms of a virus on your computer. Some signs that will help you know if your computer is safe are that your computer may be performing slower, or some files may not open. The system may keep warning you that you are under virus attack and that certain file formats have been changed.
