I have the Comcast version of Security Center v8.1. It's currently configured to run a scheduled scan each Saturday at 2AM. The scan inspects two internal drives, plus two external USB drives. Between the four drives, I have about 2TB of disk space and the scan takes approximately 14 hours. The two external drives are for backup purposes and I don't really want to scan them as part of the scheduled scan. However, I don't see any way to limit the locations that the scheduled scan inspects. Am I missing something?
