To eliminate the chance that AntiVirus, AntiMalware, and other security-related software cause corruption or lock up files in the Qlik environment, or cause issues during an installation/upgrade/patch, some folders should be excluded from live scanning.
The impact of Virus/EDR/ATP scans locking Qlik-related files (such as .qvw files, binary Qlik Sense app files as well as NPrinting task files, etc...) can result in loading and refresh failures as well as performance issues.
Please note that usual anti-virus exclusions might not apply to the EDR and ATP setup, talk to the vendor to get the exclusions in place. See Anti-virus, Endpoint detection and response and Advanced Threat Prevention exclusions for Qlik produ... for more information.
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.
This example is for Symantec. Perform the same changes using any other Antivirus and Anti-Malware product present in the environment. A different respective IT department may need to be involved in performing and confirming these changes.
Note: Steps 3 to 5 need to be repeated to add all Qlik related directories when locations are different than the default. If the "C Drive" is not the default drive for these folders then make the necessary drive letter changes.
Make sure that the anti-virus is not blocking access to certificates stored in the following location and their private keys: Personal (Local Computer), Trusted Root Certification Authorities (Local Computer), Personal (Current User for the service account)
