CFP repeats alerts for BitDefender

Help greatly appreciated! New PC with Vista Home Premium (sounds like a flavor of ice cream), installed CFP (very nice) and BitDefender (Comodo security services are too expensive) and now I get clusters of upgrepl.exe (i.e., BitDefender) alerts from CFP. I acknowledge them with Allow/Remember but a while later I get another cluster of alerts.

I found the program upgrepl.exe (C:\Program Files\Common Files\BitDefender\BitDefender Update Service) and I think I authorized it as safe, but the six or seven Comodo alerts keep coming in (infrequent) clusters. Can somebody help me make sure I am doing the auth. correctly?

What can I do to resolve this?
