Like any other program, it contains (1) that tell your computer what to do. But unlike an application, a virus usually tells your com­puter to do something you don’t want it to do, and it can usually (2) itself to other files on your computer—and other people’s computers. If you’re lucky, a virus will execute only a benign(良性的)“personality quirk”(急转,遁词,怪僻), such as causing your computer to make seemingly random bleeps.

You get a virus when you copy infected files to your computer, then (5) the code inside by running the infected application or opening an infected document. How you copy the infected files is irrelevant: Viruses don’t care if you get them as an E-mail attachment, a download file, or via a shared floppy disk, though E-mail (6) are the most prevalent (and easiest) mode of transport. Once you open an infected file or application, the (7) code copies itself into a file on your system, where it waits to deliver its payload (有效载荷)— whatever the programmer designed it to do to your system. Simply deleting the E-mail after you open the attachment won’t get rid of the virus, since it has already entered the machine. A virus writer can set the payload to trigger (引发, 引起, 触发)immediately. at a preset future time or date, or upon the (8) of a specific command, such as when you save or open a file.
