Panda Security, a provider of cloud-based security products, has unveiled the Beta2 version of Cloud Antivirus, a free, thin-client, cloud-based antivirus which reportedly halves the impact on computer performance compared with traditional antivirus products.

Panda Security said that the new version includes local and remote antivirus protection, as well as anti-spyware, anti-rootkit, heuristic scanning and a goodware cache. On average, it consumes up to 17 MB of RAM, and reportedly provides a 50% improvement in computer performance.

Panda Security claims that the new version represents a new security model based on ultra-light client/server architecture to process and block malware effectively than traditional products that rely on locally installed signature files.

By shifting the process of analyzing and identifying malware to the cloud, and applying non-intrusive interception techniques in client architecture, the new version offers advanced protection against new and unknown viruses with an extremely light, resource-friendly agent, the company said.

According to Panda Security, since Cloud Antivirus’s original launch on April 29, and with the participation of the product’s user community, more than three million new malware samples have been received at PandaLabs.
