After reading various threads re problems with kazaa / copywrite etcetera realised one of my kids is using this (don't worry heve removed admin from his profile!).
Followed advice to use kazaabegone which eventually removed all files. However.... On re-boot got message from norton antivirus saying tcp/ip was not installed and although I could log on to aol could not access any sites (including this one!). I'm running XP but used roxio goback anyway to revert and everything ok now except obviously still have kazaa.
Tried this but same problem even after simple tcp/ip installed. Reverted back again. When I check now simple tcp/ip is not installed anyway so obviously this is not the problem even though this is the message i'm getting from norton systemworks if i get rid of the kazaa files.
