Some schools in China have removed the government-mandated "Green Dam Youth Escort" web filtering program after it interfered with school computers and made it difficult for teachers to do their jobs, the Wall Street Journal reported. Beijing’s No. 50 High School posted a notice on its website this month saying, "In order to ensure a smooth operation of the school’s daily education and teaching tasks, we will gradually remove the Green Dam software soon for all the computers with internet access." Some teachers have found that the Green Dam software interferes with anti-virus programs, while others have found they are unable to access programs they need to manage students’ information and review their performance. China’s Ministry of Industry and Information Technology had initially required that all personal computer manufacturers install Green Dam on computers sold in China, but backed down after a public outcry, ordering that the software be installed only in schools and internet cafes.
