Ok this is really ridiculous. I have looked online for about 2 hours and there isn't a single method that worked. Why is the simplest thing on earth like deleting a folder has to be the hardest one? Why can't I, as a administrator delete that file? You do not own permission to delete this file, what the hell, who does then? I need to delete some files from AVG to be able to reinstall it and it won't let me. As of now I don't have any protection and I need to fix it ASAP. I won't go into details on how much XP was 130981289437FG289472389 better than vista, but meh. So there is 2 errors when I try to delete AVG 2012 from a folder and another AVG from another folder. The first one says : The action can't be completed because this folder is open in another program. Close the folder and try again. Nothing is opened? The second one asks for my permission as i've said above. Thanks for the help, and sorry about the language, but it is really stupid that administrators can't delete any files by default..
