In today's world, we rely on computers as never before. They are used for everything from ordering a pizza to running hospitals and military defense systems. Banking and credit card information is stored and accessed by computers. So what happens when a computer gets infected with a virus? One effect is that people's access to their e-mail accounts is cut off. A more serious possible consequence is that billions of dollars could be lost.
在當(dāng)今世界，我們前所未有地依賴電腦。從訂購比薩餅到管理醫(yī)院及軍事防御系統(tǒng)，計算機的使用范圍廣及各個層面。銀行業(yè)務(wù)及信用卡的資料都要靠計算機儲存和支取。假如計算機染上病毒會怎樣呢？一個影響是電子郵件帳戶的通路被切斷，另一個更嚴重的后果則是數(shù)十億的美元有可能丟失。
