It uses proprietary technology that’s been developed over three years to identify new malware applications in as little as six minutes from their release into the wild. It also handles nearly 50,000 new samples a day. To improve performance, it scans executable files immediately, but the rest of your PC when it’s idle.
It’s free because Panda wants to use data from your computer to identify new threats. What Panda hopes will be ‘millions of users’ will send heuristics info to a central server that can crunch all the data nearly in real-time.
The program takes up 50MB on your hard disk, and just 17MB of RAM when in use. Panda hopes to get this down to 12MB by the time it’s officially released. Of course, if you’re not connected to the internet, you lose a certain amount of protection, but given that the internet is the source of most virus activity, that’s not such a big issue, really.
