Install issues Antivirus eating Wip7.exe

Iam having issues with Semantics Antivirus eating my update .exe of Wip7 before it installs.

Are other having any issue with this.

Is this the responsibility of Semantics or McNeel or is it something that my IT department needs adjusting?

Some antivirus programs are more prone to give false-positives than others.
You should be able to release the exe from quarantine.
