In recent years, due to the stable security of computer system, the improvement of network security awareness and the innovation of protection software, computer virus infection events are less and less. But this does not mean that computer viruses can be eliminated. Today, with the rapid development of Internet of things and cloud computing technology, a small virus can paralyze a large area of computer systems. In order to resist computer viruses, we should take certain measures to ensure the security of computer system and data.
1. Use genuine software
Due to the high cost of using genuine software, most enterprises will choose to use pirated software, but these pirated software may contain malware and viruses. There will also be loopholes in the code copied from genuine software, so that criminals can easily crack the security license of pirated software, steal data, implant viruses, and eventually lead to the paralysis of the whole 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 go down. In order to resist the growing virus, developers have built-in anti-virus software. Therefore, by regularly updating the operating system, the virus can be kept away from the virus.
3. Install anti-virus software
Anti virus software can not only resist and prevent Trojans, viruses and other threats, but also enable us to quickly manage software and avoid the trouble of rogue plug-ins.
And anti-virus software developers often update it. They study the behavior of each new virus and update anti-virus software to compete with it.
4. Scan your computer frequently
Most anti-virus applications run automatically in the background and can resist any attack. Some attacks may not initially appear in the form of viruses and can escape attacks by anti-virus software. If you scan your computers frequently to keep them clean and safe, you can detect them.
5. Connect to the security network
Computer viruses exist not only in the system, but also in the network. If an insecure network is used, hackers can easily access your computer and steal your data from anywhere through network vulnerabilities. For your security, please always connect through SSL or TLS to make it more difficult for others to access your system.
6. Uninstall unused programs and files
When the virus enters the calculation, it will not attack immediately, but wait for the appropriate time and attack again when the appropriate file or program executes them. If there are too many unused files and programs on the computer, it can create a better environment for the virus to execute itself. Therefore, we need to delete it or uninstall it completely, not just disable it.
7. Use complex passwords
The virus not only attacks the system, but also becomes malware to steal the user’s password and destroy the computer’s data. When setting passwords for devices, we should abandon simple passwords that are easy to guess or crack, create complex passwords, make it more difficult for hackers to crack, and then protect the computer.
8. File backup
Even though users have taken all necessary precautions, sometimes some viruses are too powerful to break through protective applications. To avoid data loss, users should create a backup system to store important files and data. You can use external disks, such as memory card, hard disk, USB flash disk, network disk, 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 you log in to these phishing websites, 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 there is a threat
The most important thing is that we need to understand the symptoms of computer viruses. Some signs will help you know whether your computer is safe, your computer may slow down, or some files cannot be opened. The system may constantly warn you of virus attacks and some file formats have been changed.
