Adware/Spyware
Software that displays advertising or software that sends the user’s personal data to a third
party, often without their knowledge or consent, and for this reason may be unwanted.
Your Avira product recognizes "Adware/Spyware". If the option Adware/Spyware is
enabled with a check mark in the configuration under Threat categories, you receive a
corresponding alert if your Avira product detects adware or spyware.
Application
The term APPL, respectively application, refers to an application which may involve a risk
when used or is of dubious origin.
Your Avira product recognizes "Application (APPL)". If the option Application is enabled
with a check mark in the configuration under Threat categories, you receive a
corresponding alert if your Avira product detects such behavior.
Backdoor Clients
In order to steal data or manipulate computers, a backdoor server program is smuggled in
unknown to the user. This program can be controlled by a third party using backdoor
control software (client) via the Internet or a network.
Your Avira product recognizes "Backdoor control software". If the Backdoor control
software option is enabled with a check mark in the configuration under Threat categories,
you receive a corresponding alert if your Avira product detects such software.

installed on the computer, these programs guarantee a connection via a suitable premium
rate number whose scale of charges can vary widely.
The marketing of online content via your telephone bill is legal and can be of advantage to
the user. Genuine dialers leave no room for doubt that they are used deliberately and
intentionally by the user. They are only installed on the user’s computer subject to the
user’s consent, which must be given via a completely unambiguous and clearly visible
labeling or request. The dial-up process of genuine dialers is clearly displayed. Moreover,
genuine dialers tell you the incurred costs exactly and unmistakably.
Unfortunately there are also dialers which install themselves on computers unnoticed, by
dubious means or even with deceptive intent. For example they replace the Internet user’s
default data communication link to the ISP (Internet Service Provider) and dial a cost-
incurring and often horrendously expensive 0190/0900 number every time a connection is
made. The affected user will probably not notice until his next phone bill that an unwanted
