Removing Small
Categories: Trojan,Adware,Spyware,Worm,Backdoor,Downloader,Hacker Tool,DoS
This loose category includes a variety of Trojans that damage victim machines or
threaten data integrity, or impair the functioning of the victim machine.

Multi-purpose Trojans are also included in this group, as some virus writers
create multi-functional Trojans rather than Trojan packs.
Adware are programs that facilitate delivery for advertising content
to the user and in some cases gather information from the user's computer,
including information related to Internet browser usage or other computer habits
Spyware is computer software that is installed surreptitiously on a personal computer
to with the computer, without the user's informed consent.
Worms can be classified by installation method, launch method and finally according
to characteristics standard to all malware: polymorphism, stealth etc.

Many of the worms which managed to cause significant outbreaks use more then
one propagation method as well as more than one infection technique.

Backdoors are used by virus writers to detect and download confidential information,
execute malicious code, destroy data, include the machine in bot networks and so forth.

The downloader either launches the new malware or registers it to enable autorun
according to the local operating system requirements.
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 trojans conduct attacks from a single computer with the consent of the user.
