When I'm running the advanced cleanup they told me I have 200 mb of picture on the dropbox cache but when I look in my Gallery picture I saw all my picture are already in Dropbox. After that, I try to delete my dropbox cache and they ask me if i want to upload and delete the files (after the upload was finish) ... but I'm not sure if i will get 2 full albums of the sames pictures ... I know they create an album in Dropbox under Avast that why I'm confused (sorry I use the French version and it isn't so clear)
Thanks for your help !!
