My email in outlook on one of my computers is having the last character in the attachment file extension changed to a dash such as .pdf changed to .pd_.
In googling the problem, it is apparently associated with the "Filtering email message attachments" settings. The solution they suggest looks to be for a version of Kaspersky other then Security Cloud because it starts out by asking me to open the application setting window. I can not find it.

You’re not missing anything, you’re absolutely correct, Kaspersky has acknowledged a bug with KIS 18.104.22.1680(b), please read:
Kaspersky changing attached file names like .pdf to .pd_ apparently due to filtering attachments, raised by
Also, the same topic raised in Spanish, German, Russian, French, Italian forums.
- If there are any existing files extensions that have been changed to JP_, or similar, they must be manually changed.

If you face this issue, where Outlook email attachments are showing as blank icons and the file extension changes to underscores in the last character, for example:
".pdf" shows as ".pd_",
".docx” as ".doc_"”
".png" as ".pn_"
Email pictures included in HTML formats are also broken and the right-click properties all greyed out.
To fix this issue:
1. Close Outlook.
2. Open Kaspersky Internet Security (or Kaspersky Total Security)
3. Go to Protection (select on the left pane) -> Mail-Anti-Virus -> Advanced Settings -> make sure that only the dangerous extensions are selected: *.bat, *.сmd, *.com, *.exe, *.js, *.jse, *.msi, *.scr, *.vbe, *.vbs.
4. Open Outlook.
This solution fixes all new incoming email. Unfortunately past emails affected by this will not be changed - so to manually solve this:
1. Right click on the file in the Outlook
2. Choose "Safe as"
3. In the "File name" field change the extension by replacing the "_" with the correct letter, e.g. ".pd_" -> ".pdf"
4. Press "Save" button.
Now you can open the saved file in its saved location.
