Check On-Access Default Processes and check that you have it excluded here. Also when in here check to see if you have enabled the top option or the bottom option. If the bottom option is enabled you will need to excluide it from Low and High risk as well.
Are you sure its seeing it as a virus and its not just getting blocked by Access Protection.
How did you add the exclusion? For PUPs you do not add the exe but the identification e.g. RemAdm-VNC, RemAdm-TightVNC
