Anti-virus software scanning affects performance

Possible cause  

Anti-virus software scanning can have an effect on the performance of Qlik Sense.

Proposed action  

Configure the anti-virus software scanning so that it does not interfere with Qlik Sense. Make sure that regular scans and live/real-time scans are turned off for the following locations:

  • %ProgramData%\Qlik
  • All executables under %ProgramFiles%\Qlik\Sense
  • All executables under %ProgramFiles%\Common Files\Qlik\Custom Data
  • The file share location
  • Any additional folder path configured for storing QVF files, except for the Service cluster Apps folder (Share\Apps) which should be included in scans as it could contain user uploads. See Service cluster to locate this folder.
Note: For additional support with anti-virus software exclusions, see Antivirus exceptions for Qlik Sense McAfee, Symantec & Other Anti-Virus exclusions required.
