If your looking for a free android antivirus that did really well. Avast android is one of the few that did well and it is free.
"Mostly traditional anti-virus vendors are in the top range of the average family detection results (> 90%): Avast, Dr. Web, F-Secure, Ikarus and Kaspersky. Exceptions are Zoner and Lookout which make into the top 7 group. Using these products you don’t have to worry about your malware protection." -- AV-TEST.org
Some of the products that you should be avoiding for buying or it you have bought you should probably just remove them sense they don't do much in the area of protection are Bullguard, Comodo, G Data, McAfee, NetQin and Total Defense which had detection between (40 - 65%).
