Today we’re releasing the public beta of Panda Cloud Antivirus, which is the first free cloud-based antivirus thin-client. It consists of a lightweight antivirus agent that is connected in real-time to PandaLabs’ Collective Intelligence servers to protect faster against the newest malware variants while barely impacting PC performance.

Thanks to Panda Security’s Collective Intelligence malware and goodware online database, Panda Cloud Antivirus detects more malware than traditional signature-based solutions which take longer to detect the most recent, and therefore most dangerous, variants.

With Panda Cloud Antivirus we introduce a new protection model based on a thin-client agent & server architecture which services malware protection as opposed to locally installed products. By combining local detection technologies with cloud-scanning capabilities and applying non-intrusive interception techniques on the client architecture, Panda Cloud Antivirus provides some of the best protection with a lightweight antivirus thin-client agent that barely consumes any PC resources.

Our objective is to release a solution based on this new protection model which helps solve the malware problem by improving user experience. After almost 20 years fighting viruses and malware we have changed our mentality at Panda. We would like to open ourselves to you and show you how we pretend to do things. In this blog we’ll explain in depth how this new model works in order to help improve it with you, our users.

As for the beta objectives, we’re interested in collecting information from betatesters, evaluators, testers, etc. that can provide feedback on how the new protection model works under different scenarios in order to help us verify it as a valid model and to adapt it to real life.

Of course keep in mind that this is still beta code and as such we continue improving and tuning both the cloud architecture and detection techniques as well as the agent architecture, specially now during the initial phases. We’ll progressively release new versions which you’ll be able to use as we improve the overall protection and user experience.
