Windows Phone Thoughts: Radical New Anti-Virus Program for Mobile Devices: Too Good to be True?

"Imagine anti-virus software for handhelds that's less than the size of a typical PowerPoint file, needs no yearly subscription, yet it can protect mobile phones, PDAs, iPods or any other smart devices from not only known viruses but also all future unknown viruses and other malware. It may sound too good to be true, but that's a new anti-virus product, an Indian software company based in Madras called Sanrasoft claims to have developed . . . It takes a snapshot of a device in complete detail in its malware-free state and continuously monitors system and file changes. New files, changes in configuration, changes in system control files and changes in critical application program files are all evaluated for potential threats. Any change in the system state that represents a potential threat is immediately acted upon"

If true, then this could indeed be a breakthrough in anti-virus technology. Apparently the application will be so small that you wouldn't even know that it is present. I find it hard to tie that claim with the talk of 'system snapshots', which usually tend to be bulky. Still, they also mention preventing any unauthorized program from executing on a device, which could be hint as to how this is meant to work, i.e. only allowing 'trusted' executables to run. There are a lot of claims being made about this program and I'll believe them when I see it in person. If only a few of the promises work out, then this will worth waiting for. However, I'm more interested in the PC version, rather than the Pocket PC version. Thankfully there are extremely few viruses targeting mobile PPCs in the wild.... for now. The program should be available in the US (and presumably in the rest of the work) in mid 2006, just after the Windows PC version is released in April. What do you guys reckon? Too good to be true, or just what the doctor ordered?
