Anti-virus software is often marked down as a resource hog that is constantly interrupting your work on behalf of security. But with Panda Cloud Antivirus this concept may change.This lightweight antivirus tool takes care of your system without necessarily taking half of your resources or showing nagging windows all the time. The trick is that Panda Cloud Antivirus is based on so called cloud computing, and is only partially installed on your system and keeps core files on a dedicated server on the Internet.Thanks to this special cloud structure, Panda Cloud Antivirus doesnt have to be manually updated. Forget about complicated configurations and having to download new signature files! This doesnt mean you remain unprotected when disconnected from the network: Panda Cloud Antivirus features a local cache that keeps the program up and running, working at 100%.
