Hi Fern
People are reporting issues with NU16 and windows 8.1, I have Nu15 and on the user interface at the top right hand side there is smart updates I don’t know if this will help.
To allow selected cookies to be kept and unwanted cookies to be deleted there are two options listed below. The first option means that each browser you use will need option one performed on and if the browser has an upgrade then the process may need to be performed again. The option two covers all browsers and upgrades to those browsers.
To ensure that you are only keeping the legitimate cookies, delete all cookies first then visit the websites to collect the cookies by performing the normal tasks on the website so that the only cookies you have are the ones you require.
Disable cookies from Norton scan navigate to tracking cookies and switch tracking cookies scan to ignore, click apply, click ok.
Option one.
Use the browser concerned to deal with the cookies, for this you’ll need to use the web to find the browser and the specific version and follow the instructions.
Option two. Please check that C cleaner is compatible with windows 8.1?
Use C cleaner it has two buttons, cleaner and registry, cleaning the registry can cause serious problems so it is best to leave it alone. If you do use the registry cleaner button when it has finished there is a prompt to save the data removed to the documents folder, this data can be replaced by double clicking on the folder.
On the left hand pane of the cleaner user interface there are check boxes that can be unchecked so that the files in these locations will not be deleted.
To set selected cookies to keep in C cleaner click the C cleaner icon, click cleaner button, click options, click cookies, click on cookie to high light use arrow buttons on centre pane to move cookies from one pane to another.
C cleaner (5mb) is freeware, you might like to do some research on the web about C cleaner?
