The Payment Card Industry Data Security Standard (PCI DSS) requires full system malware scans, which are enabled on your AMS-managed VPC by default. Full system scans are set to occur at 2AM (on the time zone set on the server) because they use a lot of CPU. Full system scans are in addition to regular malware scans that do not use a lot of CPU.
There is a new Management change type (CT), Disable malware scans, that allows you to disable full system malware scans. You can find the CT in the Management | Host security | Full system scan | Disable classification, change ID ct-1pybwg08h8qsz. To re-enable scans, use the Management | Other | Other | Update CT. Disabling full system scans does not disable your regular malware scans.
