Panda Cloud Cleaner, sometimes called Panda Online Scanning, is a free Panda Security tool that scans your PC for viruses using an ever-growing collective of information it stores in the cloud for superior threat detection. It claims to find malware and spyware other programs cannot and does not require you to download any of the databases/definitions yourself as they are stored in the cloud, making signature-based detection much faster.
Since Panda Security cloud antivirus is free, it’s a useful tool but not needed if you pay for a personal or business license - that suite has its own in-built scanner that is just as, if not more, powerful.
This tool is aimed at those who know or suspect they have a problem and need a quick tool to get it fixed. They also offer a bootable USB/CD tool if your computer is so infected it doesn’t boot properly.
