After doing so, the disk usage rate of C: drive increased. It continued to increase close to 100% until the customer restarted the Anti-Malware Solution Platform (AMSP) service.
In some environments, AMSP could cause high disk input/output when the common scan cache was on. This is a known issue in Deep Security 10.0.
By default, the AMSP common scan cache is enabled. To disable it, do the following:

- Go to the Deep Security Manager root folder.
- Run the command below:
dsm_c -action changesetting -name settings.configuration.disableAmspCommonScanCache -value true
