I have the solution. For others who have AVG and may run into the same problem, here it is:
Open the AVG User Interface
Open the Residential Shield Component control panel
Under "Residential Shield Settings" click "manage exceptions"
Set the "Residential Shield Directory Excludes" to include the BIM Server
folder (probably under Program Files\Graphisoft\Bim Server)
Click OK to accept changes.
BIM Server now works as it should after a restart.
I suppose there might be a way to eliminate the conflict without excluding the whole folder, but I had no success excluding only the BIM Server Manager.exe, BIM Server Control Center and TeamworkServerMonitorService.exe files.
I hope this helps others save some time!
