Potentially Virus Checker/Firewall is interpreting the Blue Prism interfacing with accessibility technologies as a threat rather than what that application is intended to do. Go to the product support team to find out exactly what that application does. The Blue Prism product passes a number of security certifications before each release (check the start of the latest v6 release notes) and is PEN tested by most of our larger enterprise clients - so your threat is going to be just some software jumping to a presumption rather than a real threat.
