I cannot believe I cannot attach a file to a REPLY in my earlier posting concerning this issue, but can by starting a new topic. Is there something wrong about this? See the screenshot. You can see the hierarchy of the Control Design directory & there is only 1 _Model Conversions subdirectory. Note that the file CD Predictive Observer_ModelSelect.vi is within the _Inplementation subdirectory. It seems to me that MALWAREBYTES is chasing subVI’s within primary VI’s if you understand the structure of LabView. If this is indeed the case since many primary VI’s have common subVI’s then superfluous iterations will be encountered in these scans & run times could balloon to unpredictable scales. Eventually the pathname kept getting larger & repeated itself to the point it expanded beyond the view capability of the display & the scan rate slowed to less than 1 file per 2 seconds. How do we circumvent this?
