Am I correct in thinking you want to remove Findfast as it is causing you problems?
Findfast.exe is a process that is part of Find Fast Indexer. It attempts to index the Microsoft Office documents on your computer. Its main purpose is to increase search speed for Microsoft documents, but is known to create problems and can be terminated without destroying any system processes. Because computers have increased in memory size and processing speed to better search for Microsoft documents, it is irrelevant and can be removed easily and quickly from its destination folder.
