The rapid development of networks and various storage devices has greatly increased the probability of virus transmission. Although anti-virus software and network firewall can be installed to protect your system, due to the rapid development of virus technology, even many webpages contain a lot of malicious code, if the user is not aware of the attack, even if the anti-virus software is installed, it is easy to "trick ". After reading Microsoft documents and personal experience, I have summarized a set of methods to prevent viruses, hoping to help you.
If you are using a Windows 2003/xp or operating system, you can try the following methods to make your system immune from viruses at the source.
First, open the newly installed Operating System (or you can confirm that the system you are using is non-toxic:
"Start → program → Administrative Tools → Computer Management → local users and groups → users", change the super administrator password to dozens or more, try to use a password that combines numbers with uppercase and lowercase letters. Create a user, set the password to more than 10, and upgrade it to a super administrator. The purpose of this operation is to achieve double insurance: If you forget one of the passwords, you can use another super-managed password to log in and save it, so that you are not denied from the system; moreover, hackers on the Internet cannot remotely gain control of your system by making guesses about your system's hypervisor password. Then add two users, for example, the user names are nyh1 and nyh2 respectively, and specify that they belong to the user group. Now, the preparation is complete, in the future, you should not use the super administrator or nyh2 to log on to the computer except for necessary maintenance. Only use nyh1 to log on.

(When a new user is created, the default user group is used. If you want to create an administrator user, after creating the user, in the "Group", click the Administrators group and click "add" to add this account to the Administrators group .)
