This category includes a variety of Trojans that damage victim machines or
threaten data integrity, or impair the functioning of the victim machine.
Adware are programs that facilitate delivery for advertising content
to the user and in some cases gather information from the user's computer.

Spyware is computer software that is installed surreptitiously on a personal computer
to intercept or take partial control over the user's interaction
with the computer, without the user's informed consent.

While the term spyware suggests software that secretly monitors the user's behavior,
the functions of spyware extend well beyond simple monitoring.

Spyware programs can collect various types of personal information,
such as Internet surfing habit, sites that have been visited,
but can also interfere with user control of the computer in other ways,
such as installing additional software, redirecting Web browser activity,
accessing websites blindly that will cause more harmful viruses,
or diverting advertising revenue to a third party.

Spyware can even change computer settings, resulting in slow connection speeds,
different home pages, and loss of Internet or other programs.
In an attempt to increase the understanding of spyware, a more formal classification
of its included software types is captured under the term privacy-invasive software.
Backdoors combine the functionality of most other types of in one package.
Backdoors have one especially dangerous sub-class: variants that can propagate like worms.

Many trojans and backdoors now have remote administration capabilities
allowing an individual to control the victim's computer.
Many times a file called the server must be opened on the victim's computer before
the trojan can have access to it.

These are generally sent through email, P2P file sharing software,
and in internet downloads. They are usually disguised as a legitimate program or file.
Many server files will display a fake error message when opened, to make it seem like it didn't open.
Some will also kill antivirus and firewall software.

Some RAT trojans are pranks that are most likely being controlled by a friend or enemy on
April Fool's day or a holiday. Prank RATS are generally not harmful, and won't log keystrokes or hack.
They usually do whimsical things like flip the screen upside-down, open the CD-ROM tray,
and swap mouse buttons. However, they can be quite hard to remove.
This family of Trojans downloads and installs new malware or adware on the computer.
The downloader then either launches the new malware or registers it to enable autorun
according to the local operating system requirements.

The names and locations of malware to be downloaded are either coded into the
Trojan or downloaded from a specified website.
These utilities are designed to penetrate remote computers
in order to use them as zombies (by using backdoors) or to download other malicious programs to computer.

Exploits use vulnerabilities in operating systems and applications to achieve the same result.
DoS programs attack web servers by sending numerous requests to the specified server,
often causing it to crash under an excessive volume of requests.
