A few months after it bought the Android security firm ITAgents, makers of Theft Aware, Avast releases a rebranded app with some cool new features. It won't cost you a cent in gold, though: It's 100 percent free.
Avast on Android
Avast on Android brings the skin of the Windows program to the mobile device, and includes a combination of traditional security features with mobile-specific options.
Restricted to people with rooted devices is the firewall, which can disable Internet access on a per-app basis, just like a desktop firewall. You can customize the firewall's settings for each app to work with Wi-Fi, 3G, or data roaming.
Text message and call filtering are both available, along with a series of in-depth options. These include redirecting blocked calls to voice mail, or filtering based on a start and end time, or the day of the week. Outgoing calls can also be blocked, a clever tool so you can hand the phone over to a toddler without having to worry about annoying your contact list.
