Qlik Sense Folder And Files To Exclude From Anti-Virus Scanning
Qlik Sense requires access to predetermined TCP and UDP ports to function. If anti-virus software prevents traffic on these ports, Qlik Sense may not function as expected. This can include running exe files, data connections, etc.
Qlik Sense constantly updates a number of log files and also relies on multiple config and binary files to function correctly. If these files and folders are being scanned by the anti-virus software, then this may cause upgrades/installation to fail, performance issues, or cause the services to fail.

Note 1: Verify requirements on the Qlik Sense Online Help for the installed version Note 2: A machine reboot is required after exclusions are made Note 3: For Qlik Sense Desktop additional locations, see the appropriate Qlik help page for the version being installed.

The full share root folder location which includes the App folder configured in the Service Cluster. The app folder stores all app files. In latest releases of Qlik Sense, files with ".lock" extensions are generated, and each binary app file has its own .lock file. These file must be excluded from analysis as well.
It is not recommended to exclude the Static Content root folder in the Service Cluster, as this is the target location for end user uploads

Note: Qlik Support cannot provide support and services for any Qlik Servers in which performance issues, port issues, installation, patching, or upgrading problems occur if these directories are not made exempt for any and all Anti-Virus solution. It will be best-effort, as the exclusions of these directories is a prerequisite to Qlik software.
