What files and broken links are you seeing return? They could just be older apps on your system trying to access things again that are using old or broken links when they try to ‘phone home’. This would not be a Norton Utilities issue. Norton just finds the links again with the next scan.
The same would hold for your other thread on registry fixes not staying fixed. The registry changes every time you use your computer. So as you use the system, some app, possibly an older app, is creating entries in the registry that Norton finds on the next scan.
