Panda Cloud Antivirus is a free version of Panda's security software. It is cloud-based, meaning that scanning of the files is handled on a remote server rather than on a user's machine. This results in less "bloat" as seen by the end-user. The cloud technology is based on Panda's Collective Intelligence. It detects viruses, Trojans, worms, spyware, dialers, hacking tools, jokes and security risks.
Panda Cloud anti-virus is considered to be a new breed of security software since it relies on cloud (internet), the community, and collective intelligence, rather than just signatures. It requires an internet connection to function, though if internet is unavailable it runs using a cache of well-known threats.
Beta 3 (private) added Windows 7 and 64-bit support.
