Computer Virus Incident Reporting Program
This program was established and enforced in April 1990 by the Ministry of Economy, Trade and Industry
(METI) according to its computer virus prevention guidelines and encourages those who detected
computer viruses to report them to IPA so that the recurrence or the spread of such infection can be
prevented.
   While IPA responds individually to each report submitter, it also establishes countermeasures against
virus incidents, based the reports submitted. Submitted reports are carefully handled to protect the privacy
of report submitters and used solely for the purpose of analyzing damage situation and periodically
releasing our findings.
Computer Virus Prevention Guidelines:
Established on July 7, 1995 (Ministry of International Trade and Industry (MITI) release No. 429)
Revised on September 24, 1997 (MITI release No. 535)
Final revision on December 28, 2000 (MITI release No. 952)
The One Designated by the Minister of Economy, Trade and Industry:
January 5, 2004 (METI release No. 2)
