I deleted lookout after months of use, I don't think it was doing anything, it would scan an app...after it installed, which is a little late, in fact lookout put out a news release not long ago about a study they were doing and how much personal information other applications were requiring from users and what I believe is, it would scan an app after it installed (defeating the antivirus purpose) and gain information from said scanned app and then use that information for their study, soon after I read the news release, I uninstalled the app...IMO Useless....and as far as tracking your device in case of loss or theft, Mobile Defense as a system/app works great
