You will normally want to monitor your system constantly. To this end, use the Real-Time Protection (= on-access System Scanner). You can thus scan all files that are copied or opened on the computer "on the fly", for viruses and unwanted programs.
The Real-Time Protection can use a filter to scan only those files with a certain extension (type).
If this option is enabled, all files are scanned for viruses or unwanted programs, irrespective of their content and their file extension.
Note
If All files is enabled, the File extensions button 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 the 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.
Note
If Use smart extensions is enabled, the File extensions button cannot be selected.
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 "File extensions" button. This option is enabled as the default setting 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 File extensions button.
With the aid of this button, a dialog box 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.
Monitor network drives
If this option is enabled, files on network drives (mapped drives) such as server volumes, peer drives etc., are scanned.
Note
In order not to reduce the performance of your computer too much, the option Monitor network drives should only be enabled in exceptional cases.
Warning
If this option is disabled, the network drives are not monitored. They are no longer protected against viruses or unwanted programs!
Note
When files are executed on network drives, they are scanned by the Real-Time Protection irrespective of the setting for the Monitor network drives option. In some cases files on network drives are scanned while being opened, even though the Monitor network drives option is disabled. Reason: These files are accessed with ‘Execute File’ rights. If you want to exclude these files or even executed files on network drives from scanning by the Real-Time Protection, enter the files in the list of file objects to be excluded (see: Real-Time Protection > Scan > Exceptions).
Enable caching
If this option is enabled, monitored files on network drives will be made available in the Real-Time Protection's cache. Monitoring of network drives without the caching function is more secure, but does not perform as well as the monitoring of network drives with caching.
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.
Max. recursion depth
When scanning archives, the Real-Time Protection 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 files that are directly located in the main archive are scanned.
Max. number of files
When scanning archives, you can restrict the scan to a maximum number of files in the archive. The default value for the maximum number of files to be scanned is 10 and is recommended.
Max. size (KB)
When scanning archives, you can restrict the scan to a maximum archive size to be unpacked. The standard value of 1000 KB is recommended.
