ABSTRACT
This chapter discusses why updating virus protection program is critical and, if not maintained, how that program can provide very false indication of protection. Because the design of most types of attack software are structured to operate on the logical organization of data stored on disk, it concerned with a tutorial concerning data storage. The ability of a virus developer to initiate physical formatting of a hard drive requires appropriate low-level controller coding. The importance of directory entries is recognized by virus developers, who design another class of viruses to operate upon those entries. In actuality, a virus represents only one category or type of a larger category, called attack software. Other common types of attack software include logic bombs, worms, and trojans. The Detect option in the Scan menu is only applicable for finding or locating viruses. The Virus List entry in the Scan menu can be considered to represent a learning tool concerning the effect of many viruses.
