First I would like to start off by saying I am new to this site, but I feel I have a lot to offer on this subject. LookOut Mobile Security Percs: :heart: Free App for :greendroid: :heart: Anti-Virus that can be customized (daily, weekly, what part of the day you want it to scan) If you keep Anti-Virus turned on it will also auto scan any new downloads. :heart: Data Backup. This includes all your contacts, call log, and any pictures on your phone. Also can be customized as to when you would like this backup to take place. (I have 148 contacts and it takes less than 2 minutes to back up) :heart: Missing Device Based on wireless networks, and GPS you are able to make your phone go nuts, or even LOCK IT DOWN if it is lost or stolen. This is VERY handy if you have contacts that you wish not to share with others if they obtain your phone. It is also very handy if you have a G/F who always gets pissed because she loses her phone. haha :lifting: :lifting: :lifting: :lifting: PLEASE READ THIS NEXT PART!!!! I read all the comments and for the most part everyone has said the same thing. Why do you need an anti-virus for a Linux based system. Viruses on Linux are rare and far inbetween however if you relate yourself at least some with Technology trends you will know Linux (even though an older Operating system, and generally less user friendly for computer retards) is becoming more and more popular. I have many friends over seas and here in the USA that have dual operating systems on there PC. All I am saying is take precaution before you have a problem. Second. LookOut Mobile Security is the top ranking mobile security app. for phones. The company is worth more than 11million dollars. (don't believe me search it, how many other apps you use have that kind of capital) LookOut Mobile Security also does not just support Android systems. Around 18 months ago I purchased a BlackJack II. This phone was CRAP but a smart phone all the same, and one of the better ones when I obtained it. The BlackJack II uses Windows Mobile. My phone was version 2.0 then updated to 2.1, they now are up to version 6.5 to work better with Windows 7. The reason why this is important is because the apps you obtain on your android you can also get with Windows Mobile. Maybe more virus chances with windows? Either way the back up is worth obtaining this free software. If you lose your device or upgrade all you have to do is go to https://www.mylookout.com/ and restore all your contacts.
