World's first wireless virus reported by team: Confused?

Confused?

Virus, Trojan Horse, in the wild ... if you find the terminology of viruses and other nuisance programs confusing, you're not alone. Here are a few definitions to help:

Dropper

A dropper is an executable file that, when run, drops a virus. The newly discovered PalmOS/Phage is spread via dropper file. Such a file can create a virus and infect the user's system when it is executed. When a dropper file is scanned by a virus scan program, the scan will not detect the virus because the viral code has not yet been created. The viral code the virus is created when the file is executed.

In the wild

A virus that is in circulation is referred to as being "in the wild." There are now about 250 viruses in the wild.

Trojan Horse

A program that either pretends to have, or is described as having, a set of useful or desirable features, but actually contains damaging code. Often referred to as a "Trojan" for short. Technically, Trojan Horses are not viruses because they do not replicate.

Virus

A software program that attaches itself to another program in computer memory or on a disk, and spreads from one program to another. Viruses may damage data, cause the computer to crash, display messages, or lie dormant.

Worm

A worm program, like a Trojan Horse, is not technically a virus, but usually spreads via e-mail or Internet relay chat.
