Answer 5

Trojans:
* Backdoor Trojans provide the author or ‘master’ of the Trojan with remote ‘administration’ of victim machines.
* PSW Trojans steal passwords from victim machines (although some steal other types of information also: IP address, registration details, e-mail client details, and so on).
* Trojan Clickers re-direct victim machines to a specified web site, either to raise the ‘hit-count’ of a site, or for advertising purposes, or to organize a DoS attack on a specified site, or to direct the victim to a web site containing other malicious code.
* Trojan Droppers and Trojan Downloaders install malicious code on a victim machine, either a new malicious program or a new version of some previously installed malware.
* Trojan Proxies function as a proxy server and provide anonymous access to the Internet: they are commonly used by spammers for large-scale distribution of spam e-mail.
* Trojan Spies track user activity, save the information to the user’s hard disk and then forward it to the author or ‘master’ of the Trojan.
* Trojan Notifiers inform the author or ‘master’ that malicious code has been installed on a victim machine and relay information about the IP address, open ports, e-mail address and so on.
* Archive bombs are designed to sabotage anti-virus programs. They take the form of a specially constructed archive file that ‘explodes’ when the archive is opened for scanning by the anti-virus program’s de-compressor. The result is that the machine crashes, slows down or is filled with garbage data.

Spyware
Synonyms: Potentially hostile programs, Malware-related programs

‘Spyware’ is something of a grey area, so there’s no copy-book definition for it. However, as the name suggests, it’s often loosely defined as software that is designed to gather data from a computer and forward it to a third party without the consent or knowledge of the computer’s owner. This includes monitoring key strokes, collecting confidential information (passwords, credit card numbers, PIN numbers, etc.), harvesting e-mail addresses or tracking browsing habits. There’s a further by-product, of course: such activities inevitably affect network performance, slowing down the system and thereby affecting the whole business process.

The reason ‘spyware’ is such a grey area is that it’s really just a catch-all term for a wide assortment of malware-related programs, rather than a defined category. Most ‘spyware’ definitions apply not only to adware, ‘pornware’ and ‘riskware’ programs, but also to many Trojan programs: Backdoor Trojans, Trojan Proxies and PSW Trojans. Such programs have been around for almost 10 years, when the first AOL password stealers appeared. However, they were not then called ‘spyware’.

Although such programs are not new, their use for malicious purposes has increased in recent years and they have received much greater attention, both from the media and from ‘spyware’-only vendors.

The ASC [Anti-Spyware Coalition] drafted a definition of ‘spyware’ in August 2005. The ASC defines ‘spyware and other potentially unwanted technologies’ as those that ‘impair users' control over material changes that affect their user experience, privacy, or system security; use of their system resources, including what programs are installed on their computers; or collection, use, and distribution of their personal or otherwise sensitive information.’

This definition, like others, spans the whole range of maware-related programs.
