BullGuard Mobile Security 10 is a comprehensive package that brings all the power of a PC-based internet security suite (and then a little more) to your mobile phone.
There's a powerful antivirus and antispyware engine, for example, which monitors your downloads, SMS, MMS, emails, Bluetooth and infrared traffic, detecting and blocking malware before it can do any harm.
If your phone is stolen then the antitheft system allows it to be locked. You may then be able to track down the phone via its GPS tracking function, or you can use the Wipe function to destroy any confidential data that it may contain.
A firewall (Windows Mobile only) keeps your phone at a safe distance from hackers, while protecting you from a host of network attacks.
A spam filter (Windows mobile only) helps you to block unwanted calls and messages.
And a simple backup tool saves your contacts and calendar to a secure server, so it's easy to restore them if your phone is lost.
Please note, in order to use this suite you'll need a valid licence key.
