Why, what function does Prevx 3.0 preform that impacts internet monitoring ?

I run Avast! 5 with webshield and Prevx 3 with SafeOnline with no problems (see signature). Along with OA and their webshield. What other security software are you running? What is your OS? What error message are you getting from IE8?
