Symantec is launching a security program specifically designed for mobile phones. Norton Smartphone Security costs £20.

Sadly, it won't stop some chancer snatching your sleek handset off you while you're nattering to your friends, though.

Symantec Norton Smartphone Security works on both Symbian (primarily a platform for Nokia) and Windows Mobile handsets. Symantec says it is the first company to offer a single security device for both platforms.

Security companies have been warning us about the dangers of viruses getting on to mobile phones and rapidly being disseminated this way, though scepticism remains about whether there's a need for software to prevent the largely theoretical threat.

According to the recent Norton Online Living Report, 13 percent of UK adults own a smartphone but, whereas when we access the internet from our PCs we cover ourselves against malware with antivirus software, we don't protect ourselves when accessing the web through our smartphone.

In fact, according to the latest research commissioned by F-Secure, another security company, the UK had the highest proportion of users accessing the internet through their mobile device (47 percent). Brits are also the least likely to have a security product installed on their mobile phone.

Norton Smartphone Security features Norton Antvirus technology to detect mobile threats and prevent users from accessing infected files as well as a firewall to control inbound and outbound network traffic and antispam for SMS, which blocks SMS and MMS texts from unknown senders.

Available from from the end of March, Norton Smartphone Security is priced at £19.99.
