Trojan Downloader And Adware Programs
TrojanDownloader and Adware
Adware programs and modules
Adware (AdvWare or Ad-Ware) is an application used to load and show to users different advertising. We can define 2 Adware categories:
-The programs being distributed under Adware license. They show advertising as an indirect payment for programs use where advertisement is being displayed only in times of program operation and in its windows context.
-Independent applications used to show advertisement. These programs mask their presence and show commercials in pop-up windows. Though integration of commercials to desktop in form of wallpapers with possibility of WEB elements placement may be also used.
Here are some rules that the program being distributed under Adware license should observe:
Before the installation the user is informed that this is an Adware application with clear explanation of ?Adware? term. Also the installer should have an option to refuse the installation or offer a choice of installing the free Adware or paid ShareWare. The typical example of it is FlashGet download manager that offers these options. We took this example for several antispywares detect FlashGet as spyware and delete it for some reason.
The Adware module is either library that is automatically downloaded when program is running or essential part of the program. The load of Adware module occurs in time of the application starts and load-off and stop of running in time of the application execution finish. Adware modules may never integrate into other software or autorun.
Adware module may show advertisement only in his application context and may never create additional windows, execute other applications or access any web-pages.
Adware module may never act as spyware.
Adware module is jointly deinstalled with its application.
It is noticeable that Adware modules have very strict requirements they have to follow but in fact no one Adware module meets all of them.
TrojanDownloader ? programs for unauthorized download and software installation
The TrojanDownload programs (the term invented by Kasperskyy Lab) were widely mentioned before. So, here we decided to give them a clear definition.
TrojanDownloader is a software (module, ActiveX, library, etc) designed for secret and unauthorized download of software from Internet. The basic source for these programs is the hackers? websites. TrojanDownloader is harmless by itself but it endangers your PC by uncontrolled software download. They are widely used for downloading viruses, Trojans and spyware. The best-known out of them would be Trojan-Downloader.IstBar, Trojan-Downloader.Win32.Dyfuca, Trojan- Downloader.Win.32.Agent and some other. Trojan-Downloader.IstBar and Trojan- Downloader.Win.32.Agent keep the top score by the amount of modifications and harmful actions performed. Just as they appear on your PC you start noticing the programs you?ve never installed.
All TrojanDownloaders can be divided in 2 categories:
Universal ? can download any code from any server and keep their settings localized (separate file or register) or download from certain websites.
Specialized ? used to download specific Trojans or spyware. In this case files? names and addresses are fixed and kept in program body.
