If this option is enabled, all files, irrespective of their content and their file extension, 
are scanned for viruses or unwanted programs, i.e. the filter is not used. 
Note 
If All files is enabled, the button 
File extensions
 cannot be selected. 
Smart Extensions 
If this option is enabled, the selection of the files scanned for viruses or unwanted 
programs is automatically chosen by Avira AntiVir Professional. This means that Avira 
AntiVir Professional decides whether the files are scanned or not based on their content. 
This procedure is somewhat slower than Use file extension list, but more secure, since 
not only on the basis of the file extension is scanned. 
Note 
If Smart Extensions is enabled, the button 
File extensions
 cannot be selected. 
Use file extension list 
If this option is enabled, only files with a specified extension are scanned. All file types 
that may contain viruses and unwanted programs are preset. The list can be edited 
manually via the button 
File extension
. This setting is activated by default and is 
recommended. 
Note 
If this option is enabled and you have deleted all entries from the list with file 
extensions, this is indicated with the text "No file extensions" under the button 
File 
extensions
File extensions 
With the aid of this button, a dialog window is opened in which all file extensions are 
displayed that are scanned in Use file extension list mode. Default entries are set for 
the extensions, but entries can be added or deleted. 
Note 
Please note that the file extension list may vary from version to version. 
Archives 
Scan archives 
If this option is enabled, then archives will be scanned. Compressed files are scanned, 
then decompressed and scanned again. This option is deactivated by default. The archive 
scan is restricted by the recursion depth, the number of files to be scanned and the 
archive size. You can set the maximum recursion depth, the number of files to be 
scanned and the maximum archive size. 
Note 
This option is deactivated by default, since the process puts heavy demands on the 
computer's performance. It is generally recommended that archives be checked using an 
on-demand scan. 
Maximum recursion depth 
When scanning archives, the Guard uses a recursive scan: Archives in archives are also 
unpacked and scanned for viruses and unwanted programs. You can define the recursion 
depth. The default value for the recursion depth is 1 and is recommended: all archives 
that are directly located in the main archive are unpacked and scanned. 
Maximum number of files
