[QUOTE="Andy Ful, post: 965820, member: 32260"] It looks like the PowerShell execution was restricted by something. The AVs can restrict the execution of PowerShell by other applications. This is usually done by some HIPS or ATP features. If these restrictions can survive after uninstalling the AV then we have a problem. The incomplete uninstallation can be related to the presence of other security applications. The H_C can run ConfigureDefender flawlessly (from the H_C GUI) even when PowerShell is blocked by <Blocked Sponsors>. Unfortunately, Krusty has used too many security applications, so I cannot be sure what was the reason. I did not hear that KSC could produce such an issue after normal uninstallation, but if I find some time I will test KSC today.(y) Edit. Test done. I did not find a problem with KSC and H_C (including ConfigureDefender). [/QUOTE]
