From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hey, I'd like to help here with some clarification: the vulnerability affected winrar, not the RAR archive format. In fact, it happened when opening zip files, not rar files.
7zip is not only capable of extracting 7z archives, but also zip and rar. Thus using 7zip to open a malicious archive would prevent you from being a victim of said attack, which is what the previous author meant.
So you wouldn't need to change the archive format of your existing files, as this was only about not using winrar to open possibly malicious archives.
