Does my Norton retain info on uninstalled programs?

After uninstalling some apps originally obtained via online Windows App store, those apps are still shown as "loaded" by the app store even though I have run the uninstall program as instructed. Further, if I tried to re-download the app, the re-download will fail to properly d/l cause it thinks I already have it. The software mfgr. thinks it is something in my virus (Norton) program that is being retained even after the "uninstall" that tells the Store I still have the app.  Any ideas on what is wrong or where in Norton said residual data lies and can be removed?
