Nothing new here
Linux distributions already have regular security updates. I have heard Windows users complain that AV software smells of pooh so often that I am glad there is very little for Linux (There is some for filtering Microsoft malware out of email). In the Microsoft world, malware is installed and executed so it can hide and do damage before AV software can hunt for it. The rest of us don't run malware in the first place unless it is to test security.
I have tried installing some but the install scripts got tripped up by little things like mounting /tmp and /var/tmp noexec. Trivial changes to the configuration like that make most Linux boxes more trouble than they are worth. There are plenty of more complex options available for high value targets to ensure that viruses have to be targeted to a specific organisation or machine.
X86 is getting rare these days as much has been moved to AMD64, but my home also has MIPS and two incompatible flavours of ARM. Multiply that by the number of distributions and the users' choices about what software to use and you can see why Linux malware is just not as profitable as stuff for Microsoft even though some of the machines are very high value targets and Unix malware has been around longer:
This is the Unix e-mail virus. It works on the honour system. Please send copies of this e-mail to your friends then delete a few files.
