Bitdefender for android is ok but I use lookout moble security and it works better than any other moble security
But android is based on linux and linux doesn't realy have many viruses written for is since most people use windows based software so I don't realy see why u would need antivirus for android

That said, you can't really compare Android to a Linux desktop distro.
