Panda Cloud Antivirus is an excellent lightweight antivirus that takes care of your system without using lots of system resources or having nagging pop ups 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 doesn’t have to be manually updated. You can simply forget about complicated configurations and having to download new signature files!
The cloud-based functionality doesn’t 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%.
Panda Cloud Antivirus features two types of analysis: Optimized scan – which presumably analyzes the most important areas in the system, though you can’t know for sure – and Other scans, where you can select specific folders and files to be analyzed. The program includes a behavioral analysis and blocking system that detects suspicious actions typically found in malware. Another nice feature in Panda Cloud Antivirus is the USB vaccine tool, which protects your computer from potentially dangerous files in USB portable memory devices.
Though Panda Cloud Antivirus can’t be scheduled to run automatic scans and doesn’t include filters for web or email, it’s still a perfectly valid antivirus for netbooks and low-spec computers.
