are increasingly being used by cyber-criminals for malicious purposes (for

example, to collect private data, such as login credentials and social security

numbers).

Macro virus

A type of computer virus that is encoded as a macro embedded in a document.

Many applications, such as Microsoft Word and Excel, support powerful macro

languages.

These applications allow you to embed a macro in a document, and have the

macro execute each time the document is opened.

Mail client

An e-mail client is an application that enables you to send and receive e-mail.

Memory

Internal storage areas in the computer. The term memory identifies data storage

that comes in the form of chips, and the word storage is used for memory that

exists on tapes or disks. Every computer comes with a certain amount of physical

memory, usually referred to as main memory or RAM.

Non-heuristic

This method of scanning relies on specific virus signatures. The advantage of

the non-heuristic scan is that it is not fooled by what might seem to be a virus,

and does not generate false alarms.

Packed programs

A file in a compression format. Many operating systems and applications contain

commands that enable you to pack a file so that it takes up less memory. For

example, suppose you have a text file containing ten consecutive space

characters. Normally, this would require ten bytes of storage.

However, a program that packs files would replace the space characters by a

special space-series character followed by the number of spaces being replaced.

In this case, the ten spaces would require only two bytes. This is just one packing

technique - there are many more.

Path

The exact directions to a file on a computer. These directions are usually

described by means of the hierarchical filing system from the top down.

The route between any two points, such as the communications channel between

two computers.

Phishing

The act of sending an e-mail to a user falsely claiming to be an established

legitimate enterprise in an attempt to scam the user into surrendering private
