Even though cellphone viruses aren't a major problem right now, as more smartphones are deployed and 3G service becomes more widespread, mobiles will become a more attractive target for malicious hackers. Therefore it's probably not a bad idea to get proactive and put some virus protection on your phone, especially if you rock Window Mobile or Symbian, and BullGuard has just the solution for those very same operating systems. Their Mobile Anti-virus software scans any file no matter how it gets onto your device, be it through infrared, Bluetooth, WiFi, or cellular, and updates its definitions automatically over-the-air. The downside here is that your purchase only gets you one year of updates- after that we assume you have to pay a subscription fee if you don't want the app to become worthless.
