anti virus needed!!, page-32

and it points to a red circle with a small white cross ..usually means big risk n crap!!!

I think this is part of XP Service pack 2 called Security Centre.
It uses the pop up to tell you that

1 You have a problem with your firewall

2 You have a problem with widows updates

3 You have a problem with anti virus

This pop up is not your enemy as it is trying to help you.
