You might not have noticed you can download 1 month trial version of the Panda Cloud Antivirus PRO now.
You can download it from http://www.cloudantivirus.com/en/forHome/
Direct download link: http://acs.pandasoftware.com/cloudantivirus/trial/PandaCloudAntivirus.exe
Note: The trial version won't revert to the Free version after the trial expires. You have to either buy a license or uninstall it (you can of course download & install the Free version then).
