Scan
You can define the behavior of the on-demand scan routine (options available in expert mode only). If you select certain directories to be scanned, depending on the configuration, the System Scanner scans:
-
with a certain scanning priority,
-
also boot sectors and main memory,
-
all or selected files in the directory.
The System Scanner can use a filter to scan only those files with a certain extension (type).
Note
If All files is enabled, the button File extensions cannot be selected.
If this option is enabled, the selection of the files scanned for viruses or unwanted programs is automatically chosen by the program. This means that your Avira program 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. This option is enabled as the default setting and is recommended.
Note
If Use smart extensions is enabled, the button File extensions cannot be selected.
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.
Note
Please note that the default list may vary from version to version.
Additional settings
Scan boot sectors of selected drives
Scan master boot sectors
Ignore offline files
Integrity checking of system files
Note
This option is only available with Windows Vista and higher.
Note
This option should not be used if you are using third-party tools that modify system files and adapt the boot or start screen to your own requirements. Examples of such tools are skinpacks, TuneUp utilities or Vista Customization.
Optimized scan
Note
This option is only available on multi-processor systems.
Follow symbolic links
Note
The option does not include any shortcuts, but refers exclusively to symbolic links (generated by mklink.exe) or Junction Points (generated by junction.exe) that are transparent in the file system.
Search for Rootkits before scan
Note
The rootkits scan is not available for Windows XP 64 bit !
Scan Registry
If this option is enabled, the Registry is scanned for references to malware.
Scan process
Allow stopping the Scanner
Scanner priority
low
The System Scanner is only allocated processor time by the operating system, if no other process requires computation time, i.e. as long as only the System Scanner is running, the speed is maximum. All in all, work with other programs is optimal: The computer responds more quickly if other programs require computation time while the System Scanner continues running in the background.
normal
The System Scanner is executed with normal priority. All processes are allocated the same amount of processor time by the operating system. This option is enabled as the default setting and is recommended. Under certain circumstances, work with other applications may be affected.
high
The System Scanner has the highest priority. Simultaneous work with other applications is almost impossible. However, the System Scanner completes its scan at maximum speed.
