Recently Panda launched its Panda Cloud Antivirus(Beta).It has a nice interface and is easy to install and use.Rather than using your PC's processing power, this cloud-based app sends data about potentially malicious files and programs to Panda's servers for analysis. The approach is intended to take advantage of the latest signatures without the need for signature-database updates.So its a lite antivirus which doesnt take much of system's resources.
 
When you open Cloud Antivirus, the main window lets you know whether you're safe or not with a big red or green icon. Cloud Antivirus works as other antivirus solutions do, offering a Quick Scan and a Custom scan for specific folder, files, and drives, but its ancillary features are exceptionally light. You can opt out of contributing anonymous data to the cloud, but that also opts you out of automatic threat management. There's a network connection proxy option should you need it, and a reporting feature that will show you what kind of threats have been detected and removed from your computer. You can filter the report by All, Last 24 hours, Last Week, or Last Month, and there's a Recycle Bin pane from which you can recover a false positive, should you need it. Unfortunately, the Recycle Bin is hidden behind an obnoxious "flipping" screen that cheesily rotates when you need to access it.
 
Despite lacking some of the customization heft that even other free antivirus solutions have, most glaringly a scheduler, the program is not necessarily a bad choice for a stripped-down antivirus. It runs at less than 10MB of RAM when idle, and around 60MB when scanning, which should appeal to resource-conscious Netbook users. Keeping in mind its limited feature set, and that we don't have efficacy numbers at the time of reviewing, Panda Cloud Antivirus makes a decent, reasonable security choice.
