By e-mail. Users receive a file, usually in a .zip format. When the user clicks on the file or opens it, the virus will automatically spread and lock up files and programs.
答：通過(guò)電子郵件。通常情況下，用戶先是收到后綴名為.zip的文件，用戶點(diǎn)擊文件或打開(kāi)文件后，病毒會(huì)自動(dòng)傳播并鎖住文件和程序。
Once the computer is fully infected, the user can access only two files - instructions on what to do next and the virus program itself.
一旦電腦被完全感染，用戶只能訪問(wèn)兩個(gè)文件：下一步操作指示和病毒程序本身。
Other forms of ransom- ware lure users into clicking on a fake link in an e-mail or on a bogus website. It will then release a virus that corrupts the computer.
