Recently, a new antivirus program was installed on our QA servers, Trend Micro Deep Security. After disabling the software, we were able to successfully rerun our monthly reload in QA.
Moving forward, we are adding the following exclusions to the antivirus software.
C:\Program Files\QlikView\Distribution Service\*\
We have also excluded all qvw, qvd, and pgo file extensions from future scanning.
