The Extension Editor is a special feature and its use
is not recommended unless you are an advanced user. The set of file extensions
to be scanned is constantly being updated and you are provided with regular
updates as needed. Removing any of the default extensions might result in an
infection of your computer!

Extensions list
The list of file extensions to be scanned is presented in the main section of the window. Use the scroll bar on the right-hand side of the window to navigate through the list. To highlight an extension, click on it with your mouse.
Buttons
- OK - Any modifications to the
list of extensions must be confirmed using the OK
button.
- Cancel - The Cancel button closes
the window and returns control to the Setup tab.
- Add - To add an extension, click
on the Add button, fill out the dialog line, click on OK
and confirm by pressing the OK button.
- Remove - To remove an extension
(may result in security threat), highlight it, click on the Remove
and OK button.
- Default - To restore the default
set of extensions (recommended) click on the Default
and OK button.
Checkboxes
- Scan extensionless files - This
checkbox includes scanning of files with no extension.
- Scan all files - Select this option
to scan all files by default. When this option is selected the Extension Editor
reverses the function of the main dialog box: a list of extensions of the
files to exclude from scanning can be created in the extension window. In
addition, a new checkbox appears allowing exclusion of extension-less files
from scanning.
