NPD Research:

Among smartphone users, 82 percent have no security products installed on their phones; however, the percentage of users addressing this concern varies by platform, according to NPD’s “Emerging Technology Trends: Mobile Security” report. Although iPhone and Android smartphone owners share similar security concerns, 30 percent of Android smartphone owners have installed security products on their phones, compared to just 6 percent of iPhone owners.“Even though iPhone users are less concerned than Android users about device security, they are still clearly worried,” said Stephen Baker, vice president of industry analysis for NPD. “Their biggest concerns were much more likely to be fears that their iPhone would be stolen or damaged, than any unwanted or harmful activities.”

iPhone owners feel pretty safe downloading apps from Apple because of the approval process the company has in place. The Android market has been caught a couple of times with malware apps and other nastiness available for users to download.
