I am not certain, but these Issues that might not even be issues could be caused due the large amount of Hyperlinks in the starter, some seem to be suspicious, others lead to sites that are closed since quiet a while. Some links do actually not give any reasonable explanation to be in the poser starter. For me allot of them do not belong into Poser at all ! 

these are just a few of many others that are found in the starter. It gives the impression that Poser has not bee cleaned out correctly and that such things in a program sure can cause a Antivirus giving some reactions when starting it up. When the Owner is changing they should at least clean it a little out after new releases they make.
