TwainclientU is an application running under Paperport14 (and probably other versions), that I THINK finds twain-compliant scanner drivers. It freezes paperport on one of my computers and when I close it with taskmanager I get only a list of WIA scanners. This is what brought me to this site. It works as it should (invisibly) on the computer I am on now. Certainly not malware.
