Maybe, but only during full disk antivirus scans. I had some slowdown while watching HD YouTube videos during a full disk scan, but other than that, my devices ran perfectly well with Aura installed. Only cloud-based antivirus programs like Bitdefender can run a full disk scan without any system slowdown. Aura doesn’t provide any system cleanup tools, and there are way better options for gamers that want an unobtrusive antivirus option.
