So I am trying to clear my mom's laptop for her and get it running faster again, and she had the Norton 360 through Xfinity. There is a backup folder that is over 400 gigs that I just want to delete, as it is nothing she needs anymore and we are deleting everything. There's a lock icon on the folder, and when I try to delete it, it says I need admin permission to do so. This is the only account on the laptop, and it IS admin. Very frustrated with this, and I just want to get it deleted.
