One Button Checkup gives 1000" error item

I ran One Button Checkup twice to clean all the garbage out of my computerI got "no errors found" in each category after the 2nd run.

 

Then I opened the Norton website- just the home page.   I ran One Button Checkup again and it produced  974 items on the  Norton Cleanup Scan including  5 temporary files, 774 cached files and 9 cookiesAll this just from Norton's home page.

 

I have noticed that after an afternoon on line I'll have 3000+ items in the  Norton Cleanup ScanIs this unusual?
