Avtrician,
Did as you said but even with the C: \windows\temp file empty the system still manages to find the se.dll file. I have gone further and deleted everything with a .tmp file extension, the system still manages to find the se.dll file
Just received the following link from a tech support forum. Scroll about half way down to the 'Automatic removal method' to see a new adware product which claims to be able to remove the about blank problem automatically. You can download a trial version which will last for around 5-7 days before it times out and asks for the cash. I will be trying this later today and will report back.
Cheers
Whiz
