ベトナムでは95%のPCがウィルスに感染している?

Vietnam faces loose network security, data protection - People's Daily Online

俄には信じがたいが、上記のPeople's Daily Onlineの記事の内容が正しいとすると、セキュリティカファレンスでのベトナムのオフィシャルな人間の発言らしいので、それなりに信憑性のあるデータだと思われるのだが…

"The risk of data and network security breaches is at an alarming rate. According to reports of BKIS (a leading local network security center in Vietnam) and VNCERT (Vietnam Computer Emergency Response Team under the country's Ministry of Information and Communications, in 2007, some 25 percent of major Vietnamese websites are vulnerable to hackers' attacks, and 95 percent of personal computers were infected with viruses," Dang Van Hieu, Vietnamese Deputy Minister of Public Security, said at the two-day event.

According to BKIS surveys, last year, 342 Vietnamese websites were attacked by hackers, of which 224 websites were hacked by foreigners. Meanwhile, over 33.6 million computers were infected with viruses, causing estimated losses of 2.4 trillion Vietnamese dong (150 million U.S. dollars).

それにしても3360万台以上のPCがウィルスに感染って多すぎじゃね? 1.5億ドル程度の損失っていうのもなぁ。算出の根拠となる数字が知りたいところだが。
