I tested Panda Cloud Antivirus extensively on my systems while it was in beta and only recently switched to Microsoft Security Essentials (MSE) for evaluation. Today, I’ll switch back to Panda on my older, slower system to compare performance of each one. I have noticed a slight performance degradation with MSE that was all but non-existent with Panda. Now that Panda Cloud Antivirus is out of beta, I can make a fair comparison which I will report on later. Check out the full report in this Security Corner post.
