I suspect the panda cleaner issue relate to unencrypted virus signatures, so not really an FP when you have a signature based scanner looking for signatures.
Believe it or not it does, if it were a true cloud scanner why is the actual installation so large. We have seen this befor with the panda cloud AV that purports to be compatible with your AV.
If this is only a cleaner as you stated earlier, it has to know what it is looking for to clean, for that it would require a signature/s.
