Welcome to the Community Forums.
There could be a number of reasons for this including that it or the download it came in is infected with malware or suspicious content. But most likely it is a false positive and to check this I would Open a Support Ticket to advise the Support Team of the issue and let them review the Scan & Threat logs for your system (automatically uploaded when the ticket is opened).
They should be abe to advise as to the cause and rectify the problem if it was due to a false positive.
