A conflict occurs when McAfee Virus Scan operates on a machine using Threatfire Virus Scan. When these anti-virus applications run simultaneously, most of the ArcGIS 9.3 Geoprocessing tools in ArcToolbox, as well as many exporting functions, generate a generic 99999 error and do not function.
PC Tools Threatfire 184.108.40.206 and later versions are causing a conflict when it is run simultaneously with McAfee Virus Scan.
