There is no Linux viruses, it is not a Business, and Android, although based originally as a Linux-based operating system, once Google bought it, it changed very much from your General Linux GNU Operating Systems which run the largest Super Computers on the Planet, CERN, the world’s largest particle physics laboratory, and recently the International Space Station.
Android is explained: http://en.wikipedia.org/wiki/Android_(operating_system)
As of May 2013, a total of 900 million Android devices have been activated and 48 billion apps have been installed from the Google Play store.
I see relatively few similarities to the Linux Operating System I describe above. No checks and balances, just a huge 'free for all' in a huge open Market.
Please when you find a Linux Virus, PM me as I want it, and have many who would also love to see such a curiosity. 
But yes polonus, it is Linux at it’s worst, with Google at the Helm, and so many Apps a Hacker’s Paradise.

"...You are not in the Windows world anymore and there are no Linux viruses in the wild, or otherwise.
All attempts to create a Linux virus as "proof of concept" have also failed, in that they required active participation from the root user to install, and even then, failed to propagate.
You may believe that as Linux gains popularity there will be viruses magically appearing, but you are wrong. There's a better chance that Santa Claus will drop down your chimney to give you presents, the Easter Bunny will drop off a basket of colored eggs, or the Tooth Fairy will pay for, and come collect your lost teeth, than you will get a Linux virus.
If you insist on installing AVG, use the RPM package they provide. Unless you plan to use it to scan email to be forwarded to Windows computers, you’ll find it a waste of time, effort, and resources."
