In recent years, the rapid development of the internet environment has led to the widespread use of smart devices and a decrease in the age of users. If not properly managed, it can become an entry point for adolescents and children to access inappropriate information. Therefore, the Ministry of Education and Trend Micro Inc. are collaborating to promote the importance of internet safety for children, and have jointly launched the "PC-cillin Home Network Guardian 2.0" for free download. This aims to help teachers and parents create a positive online environment for adolescents and children, establish good internet usage habits, and keep them away from potential cybersecurity threats.
