I am experiencing a performance issue in my application when using the CallVirusCheck activity to scan files. The application uses customized Java code integrated with a third-party antivirus. However, when attaching a document, the system takes approximately five minutes to load before eventually throwing the following error:

D_pzRunRecord.pxRunWindow(TABTHREAD1).pxRunParameters.pySteps(2)

This issue is causing significant delays in processing attached files. I would appreciate your assistance in identifying the root cause and providing guidance on resolving this performance bottleneck.
