Avira OS?
 

Is there an Avira OS? I found it on distrowatch, but it links to Avira's site but what it is is not clear, although the program comes as an ISO.

What does this do?

I'm running Avira Security on my PC. It's an anti-virus / firewall software package. I wasn't aware they were in the Linux business as well.
Hmm, I've been Googling. Using "avira rescue cd" as query. 2nd link seems to indicate it's a repair tool. Not a Linux distro.

Yeah, it's "a Linux-based boot disc that will detect and remove malware from a damaged PC". It just runs kernel 2.6.35.1, Busybox and IceWM.
