My neighbour, who can't get on line at the moment, gets a blue screen every time he tries to open Internet Explorer, or send emails. He recently had his HD reformatted and everything reinstalled. He uses Panda Titanium which he says is up-to-date. His 9-year-old daughter has gone on line and downloaded games etc - whic I guess may be part of the problem. I think he uses WIN 98. Any ideas please?
