它是一个可以记录用户键盘操作的间谍软件。黑客可利用此软件记录用户输入的信息。此软件和病毒完全不同，是正规软件，目前大概有两类软件。一类是模仿操作，用途是做重复操作 　　按键精灵就是其中之一；还有一类是用于家庭监控的软件，如梦真工作室开发的键盘屏幕全记录。(The virus is completely different from a regular software, currently there are about two types of software. A class is to imitate the operation use repeat QuickMacro there is a class of software for home monitoring, keyboard screen Full Record dream real studio.)
