Linux Mint

Linux Mint is an Ubuntu-based distribution whose goal is to provide a more complete out-of-the-box experience by including browser plugins, media codecs, support for DVD playback, 

Java and other components. 

It also adds a custom desktop and menus,
several unique configuration tools, 

and a web-based package installation interface.
Linux Mint is compatible with Ubuntu software repositories.

With linux mint you don't need a antivirus 

because it has no register to worry about.
