Thanks very much for your help and for clearing that up, DavidR. It’s a relief to know avast is not infected.

I was in
gmail and then opened a link from
wxw.megaupload.com which gave me a pop up for partypoker
and MSN with a friend in Holland which seems to be where that ip address is from

was my MSN be infected and trying to spread 'outgoing ’ malware to my friend?
