computer, without the user’s knowledge. This program is manipulated by
third parties using a backdoor client via the Internet or local network.
cron (daemon)

Daemon
A background process for administration on UNIX systems. On average,
there are about a dozen daemons running on a computer. These processes
usually start up and shut down with the computer.
Demo version
Without a license file, AntiVir UNIX Server runs as a demo version and it
only reports the test virus EICAR. It will not block access to infected files.
The update function is not available.

up a premium rate number Internet connection, charging you at high rates.
This can lead to huge phone bills.
AntiVir detects Dialers.

Heuristic

typical virus-like functions are found, the respective macro is classified as
"suspicious".

elementary functions (e.g. memory and process administration).
Logfile
also: Report file. A file containing reports generated by the program during

harm other users.
For example, mail bombs: with such a program, the victim can be attacked by
