SessionCreator to run a FinalBuilder project

We have a buildserver that runs a script in FinalBuilder that does a complete build, unit tests of that build and tests with TestComplete.
However, this server is logging out because of company policies. The scheduled task that will start the FB script will only run if there is a user logged in (because there are a lot of GUI tests from a Delphi application that require an actual screen defined, compared to what SessionCreator uses)

My idea was now to make a testproject, activate it from a session in SessionCreator, that will open FinalBuilder and run the script.

It does start, but after about 10 seconds it stops and the services of TestComplete are being quarantined by the virusscanner.
The virusscanner is managed by the HQ of the company, so excluding the TC folder from scanning is not possible.

Any ideas how to do this?
