Cisco Secure Client claims dangerous data in IcingaForWindows.ps1

Hello,

during this year we switched from Sophos to Cisco Secure Client as antivirus software on our windows systems. Today we tried to install IfW on another system and got blocked by Secure Client:

In C:\Users\Public\IcingaForWindows.ps1:1 Zeichen:1
+ <#PSScriptInfo
+ ~~~~~~~~~~~~~~
Das Skript enthält schädliche Daten und wurde von Ihrer Antivirensoftware blockiert.
    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : ScriptContainedMaliciousContent

Is the problem known and is there a workaround? We can define an exception in the policy for the system, but that would be a problem for the entire campus.

Regards
Berthold Cogel
