2. Detection Number of Virus
As with the detection number, the reported number of virus was also tended to decrease. The major cause was that the detection number of W32/Netsky, the mostly reported virus, was decreasing. Because of the installation of anti-virus software is getting promulgated, it can be viewed that the infected computers are decreasing in their number.
According to the survey result*1 conducted by IPA relevant to the information security measures, “Updating of security patches by Windows Update” and “Installation/leverage in anti-virus measures software” were implemented by about 80% of users. In addition, about 90% of users recognized that “the attachment file(s) to suspicious e-mail(s) should not be opened”; accordingly, the necessity of information security measures is being penetrated among users.

As its results, the detection number itself is decreasing, but the reports relevant to W32/Netsky continually takes over almost the entire reported number.
