File Types To Scan

There are three main options for this feature:

    2. Scan selected extensions: You can specify extensions from a list of extensions. To do so, do the following:

    1. Select the extension from the left list box.

    2. Click Add to add the extension to the File types to scan list

    To remove previously excluded extensions, do the following:

    1. Select the extension from the right list box. See above for multiple selection instructions.

    2. Click Remove to clear the extension from the File types to scan list.

    1. Other extensions: Type custom file extensions in this text box. Use colons (:) or semicolons (;) to separate entries.

Compressed File Scanning Options

To enable compressed file scanning, do the following:

  1. Select Scan compressed files.

  2. Specify the number of compression layers to scan. The permitted values are from 1 to 20.

  3. Specify the maximum file size that is extracted for scanning. The minimum value you can set is 1-MB, while the maximum value is 2000-MB.

Action When Security Risk Found

Do the following in this section:

  1. Decide whether or not to back up files before performing an action. To create copies of the files, select Back up file containing security risk before action is taken.

  2. Select an appropriate action from the following:

For viruses and other security risks you may also specify a secondary action, in the event that the clean action fails. Select the action in the drop-down list in the Second Action column. The secondary action is performed only if the first action performed is not successful.

The following table shows the default action for each type of threat when customized scan action is selected.
