has any one elss had this popup. Happens completely at random. I have tried Ad-aware, Spybot and clearing the cache. ZoneAlarm dose not pick it up.

I used to have that problem like crazy, but not anymore. Either it was my windows updates or my norton's firewall, I don't know. Make sure your windows is updated through that automatic update thingy, in case that have one of those security patches for it.
