*Reported number for 1990 was the number aggregated from April to December.

The damage from infected computers (actual damage) was tending to decrease year by year: the ratio for actual damage was 0.4% for 2005 and was 0.2% for 2006. It seemed that certain security measures such as installation of anti-virus software to mail server, etc. were widely penetrated/accepted among users' community.
