The driver is failing signature validation on Windows 8.1. You'll probably want to open a case with TAC and share these logs so that they can validate if its a systemic issue across 8.1 running the latest updates or not since Windows 8.1 is a supported release for GlobalProtect 6.0. I unfortunately don't keep any Windows 8.1 images around to see if this is reproducible or not.
