@anyone frustrated and willing to try Linux, give Fedora Linux a go. It's a really solid pick for first time users and has great security defaults.
Some people will be nervous because Fedora used to be a 'slightly harder' distro but this is no longer true IMO and I would actually consider it easier for many cases (in particular: stock GNOME is way more consistent than Ubuntu gnome).
If your friend is nagging you to start with an Ubuntu distro, Kubuntu is a really good one for ex Windows users. The KDE desktop actually pioneered some of the desktop patterns that Windows has adopted (and of course vice versa).
