A computer virus – an unwanted program that has entered your system without knowing about it – has two parts, which are called the _______and the______. They have two very different jobs. One of the _____of a computer virus that _____it from other kinds of computer program is that it _____ itself, so that it can spread (_____ floppies transported from computer to computer, or networks) to other computers.
After the infector has copied the virus elsewhere, the deto¬nator _____ the virus's main work. Generally, that work is either _____ data on your disks, altering what you see on your computer display, or doing something else that__ with normal use of your computer.
Here's an example of a simple virus, the Lehigh virus. The infector portion of Lehigh replicates by ______a copy itself to COMMAND.COM (an important part of DOS), enlarging it by about 1000 bytes.
So,   let's   say   you   put   a   floppy   containing   COM-MAND.COM into an infected PC at your office – that is, a PC that is ______ the Lehigh program. The infector portion of Lehigh  looks over DOS's shoulder, monitoring all floppy _____. The first time you tell the infected PC to access your ____,  the  Lehigh  infector notices  the  copy of COMMAND.COM on the floppy and adds a copy to itself to that file.
Then you take the floppy home to your PC and _____from the floppy. (In this case, you've got to boot from the floppy in order for the virus to_____, since you may have many copies of COMMAND.COM on your hard and floppy disks, but DOS only uses the COMMAND.COM on the boot drive.)
Now the virus has silently and ____been installed in your PC's memory. Every time you access a hard disk subdi¬rectory or a floppy disk containing COMMAND.COM, the virus sees that file and infects it, in the hope that this particular C0MMAND.COM will be used on a boot disk on some com-puter someday.
Meanwhile. Lehigh     ____ of infections. Once it has in¬fected four copies of COMMAND.COM, the detonator is _____. The detonator in Lehigh is a simple one. It ___ a vital part of your hard disk, making the file   on that part of the disk no longer accessible. You grumble and set about rebuild¬ing your work, _______that Lehigh is waiting to infect other unsuspecting computers if you boot from one of those four infected floppies.
