I have downloaded an update for my Outlook98 which will block all dangerous
attachments. The virus we got was blocked because of this, even if I want to
open it I might not be able to do it.
Not showing the last extension is a setting in Windows, so a virus can hide
life stages.txt.shs or something like that. The innocent user thinks he
opens a text file which can't contain a virus.
This setting can be changed in the registry, be careful when editing and
make a backup first.
The following text is from www.nai.com about this subject:
One significance of this exploitation of SHS files is that it raises
awareness to the fact that the extension is not shown, even if a system is
configured to "show all files" and "show extensions of known file types".
This is due to a registry entry for Shell Scrap file types:
HKEY_CLASSES_ROOT\ShellScrap
"NeverShowExt"="0"
Users can correct this by either deleting the entry named "NeverShowExt" or
rename it to "AlwaysShowExt". If renaming the entry, user must log off and
log back into Windows for the change to take effect.
I hope this is of help,
Frits
