Computer Virus Incident Reporting Program

The Ministry of Economy, Trade and Industry announced "Computer Virus Prevention Guidelines" to prevent the spread of computer viruses in Japan. IPA was designated to receive the "Computer Virus Damage Report" directly from the infected users to investigate virus problem and to provide monthly statistics. This reporting system started in April 1990. Anyone who has encountered computer virus is supposed to send a virus report with necessary information to IPA to prevent further spread and damage of viruses. IPA deals with each reporter (user) on an individual basis as a consultant, and also works as a public research institute for anti-virus measures by analyzing problems showed on the damage report. Taking reporters' privacy into full consideration, IPA periodically publishes the result of their research and analysis on computer virus incident.

Computer Virus Prevention Guidelines:
  • Enactment on April 10, 1990 (release No.139)
  • Amendment on July 7, 1995 (release No. 429)
  • Amendment on September 24, 1997 (release No. 535)
  • Amendment on December 28, 2000 (release No. 952)
  • Amendment on January 5, 2004 (release No. 2)
