Disabling Executable Attachments
In order to protect our users from viruses, SVPAL implements
an attachment filter to disable executable email attachments. The
vast majority of these attachments contain viruses. This process does
not affect typical email that contains plain text, HTML (Rich content),
email, images, videos, flash animations, or sound files.
scanning software functions by detecting previously identified
viruses. This means that new unidentified viruses are not
caught. The filter used by SVPAL functions by disabling ALL
executable attachments, thereby catching most all viruses whether or
not they have been identified.
The following is a partial list of attachment types that are
considered "unsafe" and are disabled by the filter: EXE, PIF, LNK, SCR,
VBS, DLL. Unsafe attachments have their file name extensions
renamed to TXT. Microsoft Windows does not execute files with the
suffix of TXT. It instead opens such files with the Notepad
program and displays their contents. This is harmless as it does
not launch the virus.
On rare occasions the filter may disable legitimate executable attachments. In this case, the following section describes how to restore the attachment to executable status.
Enabling a Disabled Attachment (use with caution)
If you receive a legitimate executable attachment in email,
you can still execute it. However,
be certain that you want to
do this and that it is not a virus. If there is
any doubt, do not execute the attachment. Use these directions
at your own risk.
Save the attachment as a file on your computer. If the
file's original attachment type was EXE, then rename the file so that
the extension is again EXE. For example if the filename is
currently SETUP.TXT, then rename the file to SETUP.EXE. If the
file is a ZIP archive, for example STUFF.TXT, then rename the file to
STUFF.ZIP. Windows will warn you against renaming the file
extension, but you may proceed.
After renaming the file, double-click it to activate the program, or open the ZIP archive.
