Currently, malware’s biggest target is the PC. But it’s likely it will migrate from the PC to the smartphone and tablet as our computing habits change. Unfortunately, there will always be spammers, scammers and hackers.

A few months ago, nearly 60 Android apps were caught uploading information about smartphone hardware, unbeknownst to the phones’ users. What’s worse, these apps created "back doors," so additional (and potentially more sensitive) data could be downloaded in the future. Google remotely eliminated these apps from smartphones, removed them from the Android Market, suspended the developer’s accounts and notified authorities.

Follow these tips to protect your smartphone:

1. Keep your operating system (OS) up to date. OS updates often include security fixes, so stay current. You can generally find info about your phone’s OS version in the “Settings/Options” or “About Phone” area. When in doubt, ask your carrier.

2. Occasionally clear your smartphone’s browser cookies and cache.

3. Be aware of your smartphone’s vulnerabilities. Generally speaking, RIM’s BlackBerry platform is considered to be the most secure, followed by Apple’s iOS and Windows Phone 7. The problem with Android is its open-source nature: Anyone can freely develop for the platform. While many people prefer this to Apple’s more guarded approach, it unfortunately means you might be compromising some privacy and security.

4. Be cautious when downloading apps from little-known developers. Read reviews, visit the developer’s website and don’t rush to download apps. When a new app comes out, wait a month or so before downloading it if it comes from an unfamiliar source. That way, you can see whether anyone else reports problems.

5. Don’t open unknown attachments. Just as you wouldn’t click on a suspicious email attachment on your computer, refrain from doing it when reading email on your smartphone.

6. Look into security software. Many computer security software companies are creating versions of their PC software for smartphones. Look into whether the company you already use for PC protection offers a mobile version for your phone. There may also be security- and privacy-based apps in your smartphone’s app store.
