The chairman of Trend Micro, Steve Chang, has said in an interview with Bloomberg that Android is way less secure than the iPhone. He explains how Apple‘s closed system won’t allow a virus to execute code deep in the OS:

“Apple has a sandbox concept that isolates the platform, which prevents certain viruses that want to replicate themselves or decompose and recompose to avoid virus scanners.”

Whereas Android’s open system is much easier to gain access to:

“Android is open-source, which means the hacker can also understand the underlying architecture and source code.”

Apple’s iOS still had its vulnerabilities within Safari (remember the JailbreakMe exploit) but said:

“We have to give credit to Apple, because they are very careful about it.”

Trend Micro makes an antivirus app for Android and some light security apps for iOS.
