Configuration :: Guard

Scan

You will normally want to monitor your system constantly. To this end, use the Guard (= on-access scanner). With this you can scan all files that are copied or opened on the workstation for viruses and unwanted programs "on the fly".

Scan mode

(This option is not available for Windows 98, ME.)

Here the time for scanning of a file is defined.

Scan when reading

If this option is enabled, the Guard scans the files before they are read or executed by the application or the operating system.

Scan when writing

If this option is enabled, the Guard scans a file when writing. You can only access the file again after this process has been completed.

Scan when reading and writing

If this option is enabled, the Guard scans files before opening, reading and executing and after writing. This option is enabled as the default setting and is recommended.

Note
To obtain maximum security, you should have enabled this option. However, please note that this may reduce the computer performance, as files may be scanned more than once.

Files

The Guard can use a filter to scan only files with a certain extension (type).

All files

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.

Use file extension list

If this option is enabled, only files with a pre-defined extension are scanned. All file types that may contain viruses and unwanted programs are pre-defined. The list can be edited manually via the button File extension. 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 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 the 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.

System shut down

(This option is only available for Windows 98, ME.)

Alert if disk in drive A:

If this option is enabled, AntiVir PersonalEdition Classic Guard checks whether there is still a disk in disk drive A: when shutting the system down. If this is the case, you receive a corresponding message.

This option is useful, as many viruses are still spread via the boot sectors of disks. If you have left a potentially infected disk in drive A: when shutting down and the start option in the BIOS of the computer is set to A: / C: there is a risk of infection with a boot sector virus the next time the system is booted. When you see the message "No system disk or disk error" or "Non-system disk or disk error", a potential virus may already have infected your system.

Archives

(This option is not available for Windows 98, ME.)

The Guard can monitor files that have been compressed with run-time packers.

Unpacking run-time compressed files

If this option is enabled, the files are scanned, decompressed and scanned again. Viruses and unwanted programs hidden in these files can also be found in this way. This option is enabled as the default setting and is recommended.

Drives

Local drives

If this option is enabled, only files of local drives such as hard disks, CD and disk drives, MO and ZIP drives etc. are monitored. This option is enabled as the default setting and is recommended.

Warning
If the options are disabled, the relevant drives are not monitored. You are no longer protected against viruses or unwanted programs!
