Annoying Security alerts

Recently I've begun getting a popup message FROM Norton every minute informing:

Security Request

Outbound Traffic Detected

We have detected a large amount of suspicious outbound traffic ... etc.

Running Power Eraser as recommended does not fix this.

The bit of info I can dig up for this is that it may involve groupstyleusa.info and/or profile-valid.com -- not sure though.

ANY ideas would be appreciated -- thanks!
