Base filtering engine is preventing FTP uploads

Question

Using win 8.1. Ftp uploads (from any ftp program, filezilla, winscp and with knowhow cloud backup) stalls after 2-3 files have been uploaded.  A single large file will upload but not multiple small files. If I boot into windows safe mode the problem
does not occur, ftp works fine, always.  In normal mode by eliminating one running component at a time I found that the base filtering engine appeared to be the only problem.  If base filtering was running the ftp problem occurred, if not then ftp
was fine.
Can one repair or replace the base filtering engine?.    I found this as it relates to win 7
FROM ONE OF YOUR OTHER THREADS:
you may download and apply the BFE service registry fix (#11) in this page: Miscellaneous Registry Fixes for Windows 7/XP/Vista - The Winhelponline Blog: LINK REMOVED (could not submit, Body text cannot contain images or links until we are able to verify
your account.)
Is that applicable for this problem in win 8.1?
I do understand the BFE is an important security issue.  I have also scanned my system for viruses, I use defender (computer associates) anti virus and firewall, and spybot for malware.  I can't specifically pinpoint the occurrence of the problem with
the installation of any specific new software program.  I have disabled the defender  firewall and virus software and that does not solve the problem. Disabling base filtering engine results in a functioning ftp, enabling results in
a stalled ftp.
Any help would be appreciated.

1. Browse to the location for the BFE service in the registry (HKLM\System\CurrentControlSet\Services\BFE\Parameters\Policy), right click and select permissions.
2. In the "Permissions for Policy" window, click advanced | Add.
