How to prevent Trojan virus from affecting other disks by installing dual systems?

To prevent computer poisoning, the first and most important thing is to do a good job in the computer's own preventive measures and improve the resistance of its own computer system, which also requires users to understand basic computer prevention knowledge. Here are some specific knowledge and methods.

Make necessary settings for the basic system of the computer itself.

The common methods of setting hard disk partition and formatting protection in CMOS settings of computer motherboard are: enter CMOS (press Del key after startup or reset or warm boot) → select BIOS.

Function Settings "→ Select Virus Warning" → Set to Enable "→ Press ESC → Select Save &; export

After setting, press Enter → Select Y, and then press Enter → Restart. The repartition and formatting of computer hard disk will be protected in the future.

Set the security of Windows system, open the firewall and other preventive tools. And upgrade in time. Or download computer security software with high security and good reputation, such as 360 security guards and QQ doctors. , and use these software to fix Windows vulnerabilities in time, clean up junk and common Trojan horses and other viruses. Of course, these software tools should be upgraded in time, because viruses will also attack and infect old antivirus software.

Set the firewall of the router, control the IP address of the computers in the LAN, and preferably use the physical address to prevent other external computers from entering and damaging the internal system.

Buy genuine antivirus software and learn the basic operation and use.

Do a good job in the management of your own internal documents. Manage your computer data like a professional librarian and store it in different spaces according to different categories and importance. It is best not to store important text files on the system disk (general C disk). At the same time, make backup, just in case. You can also use the recovery function of Windows or Ghost software to back up the system.

You can strengthen the filtering function when surfing the internet. When surfing the Internet, people call computers without preventive measures "vegetable machines". In fact, this kind of computer is being used by others at any time, using your computer to publish information and steal computer information. Your computer is like a house with doors and windows open. For professionals, you can enter and leave freely. Therefore, you should lock the door and close the window. For example, the Fairfax firewall can be set up and managed here to prevent unnecessary "uninvited guests" from disturbing and prohibit others from accessing your computer.

Of course, all firewall software and antivirus software are not omnipotent, so they should be used comprehensively. The most important thing is to have a sense of computer security and learn to improve this knowledge.
