3.7 Installation modules
In a user-defined installation or a change installation, the following installation modules can
be selected, added or removed.
Avira Free Antivirus
This module contains all components required for successful installation of your Avira
product.
Avira Realtime Protection
The Avira Realtime Protection runs in the background. It monitors and repairs, if
possible, files during operations such as open, write and copy in on-access mode.
Whenever a user carries out a file operation (e.g. load document, execute, copy), the
Avira product automatically scans the file. Renaming a file does not trigger a scan by
Avira Realtime Protection.
Avira Web Protection (for Avira Free Antivirus users, only in combination with the
Avira SearchFree Toolbar)
When surfing the Internet, you are using your web browser to request data from a web
server. The data transferred from the web server (HTML files, script and image files,
Flash files, video and music streams, etc.) will normally be moved directly into the
browser cache for display in the web browser, meaning that an on-access scan as
performed by Avira Realtime Protection is not possible. This could allow viruses and
unwanted programs to access your computer system. Web Protection is what is known
as an HTTP proxy which monitors the ports used for data transfer (80, 8080, 3128) and
scans the transferred data for viruses and unwanted programs. Depending on the
configuration, the program may process the affected files automatically or prompt the
user for a specific action.
Avira Rootkits Protection
Avira Rootkits Protection checks whether software is already installed on your computer
that can no longer be detected with conventional methods of malware protection after
penetrating the computer system.
Shell Extension
The Shell Extension generates an entry Scan selected files with Avira in the context
menu of the Windows Explorer (right-hand mouse button). With this entry you can
directly scan files or directories.
