I am a big fan of Avast Security, because it's available for Linux/Windows and Android.
So I don't have to get used to 3 different GUIs to maintain the virus/spyware defense on my devices.
Besides this usability advantage, the virus recognition of Avast Antivirus free offers the same capabilities than the ultimate version which is one of the best currently available.
To answer some of the previous posts: I think mobile virus detection is becoming more and more important, because the more people use mobiles for i.e. mobile payments the more hackers will try their luck on hijacking them. And Android security patches are updated around every 40 days only.
