________ manifest(s) in several ways, including changes to the browser, redirecting startup pages on Internet browsers, replacing the search function within the browser, and generating pop-up ads and frames that can be difficult to delete or shut down.

Adware

Malicious code attacks that combine elements of worms, Trojans, and viruses are known as:

Blended threats

________ viruses operate based on algorithms of starting an operating system upon power on or reboot.

Boot

________ can reach very large sizes and may include thousands of machines.

Botnets

The first vastly spread virus was called "________."

Brain

Some researchers use the term ________ as a reference to the programs and tools that facilitate fraud and computer attacks.

Crimeware

A ________ uses multiple systems to attack one or more victim systems or websites with the intent of denying service to legitimate users wishing to log on or utilize the attacked server.

Denial-of-Service attack

A worm cannot spread without active intervention by the user.

False

Adware typically takes advantage of the fact that many software users do not read the end user license agreement (EULA) or the fine print during installation.

False

Apple computers are immune to viruses.

False

Boot viruses do not change infected files, but instead close the target file so that when run they "force" the OS to execute their code.

False

The main operating principle of a macrovirus is its capability to transfer its code to a remote service or workstation on its own.

False

The motives for many writers of malicious software have changed from profit to curiosity and revenge.

A virus can be categorized based on:

The type of environment it operates in

Virus

These operate in four primary environments. One form of this threat takes advantage of macro- languages built into common systems of business software. This type of threat operates based on the algorithm of starting an operating system upon power or reboot.

Trojan horse

This does not replicate nor copy itself. One form of this threat logs the keystrokes of the victim, allowing the attacker to search for passwords in the log file. A well-known form of this threat is named Sub7.

An unauthorized program typically contained within a legitimate program is known as a:

Trojan
