We have to confess that Panda Cloud Antivirus 2.0's benchmarks surprised us. We expected it to leave a small footprint on the system, but not be particularly effective at stopping threats. In fact, the benchmarks tell the opposite tale.
Two independent testing organizations placed Cloud AV 1.5.2, the most recent version for which test results are available, much higher on its efficacy charts than we expected it to be.

It was made even more noteworthy because it outperformed its cousin, Panda Internet Security, which only earned a 13.5 out of 18.
