How do I troubleshoot ArcGIS Desktop performance issues related to antivirus software (exceptions)?
Anti-virus software can prevent ArcGIS for Desktop from quick start, or at least prevent a high-performance startup. This article introduces some recommendations for antivirus (AV) exclusions related to ArcGIS Desktop that may cause this issue. This content is mainly to help administrators to determine the cause of potential instability on a computer that is running a supported version of ArcGIS Desktop when it is used with antivirus software.
Warning: We recommend temporarily applying these procedures to evaluate the system. If system performance or stability is improved by the recommendations made in this article, contact your antivirus software vendor for instructions, or for an updated version of the antivirus software.The following adjustments can be made to an antivirus program to make ArcGIS Desktop run better:
\arcgis \Program Files (x86)\ArcGIS\ \Program Files (x86)\Common Files\ArcGIS\ \bin\ArcGIS-Starter\ \Program Files\ArcGIS\ \bin\Python27\
Note: When excluding a directory that has a name greater than eight characters long, add both the short and long names to the exclusion list. These names are required by some AV programs to traverse the subdirectories.
