Norton Clean Sweep sucks, that's right, but it's good to create install logs.
DONT'T USE IT TO UNINSTALL PROGRAMMS!!!!!!
Only use NCS to create log files of citical programms.
When you have allready installed the programm run ncs and install it again, now you had an full install log, and you could delete all the files and entrys manually.
Do you know what i mean?!
