Why choose system drive and then the C:\Users\Justin\Downloads it is on the system drive.
I don’t see much benefit of scanning your bittorrent downloads folder, if a) you are using the P2P shield and or b) you have avast scan the completed bittorrent download (ashQuick.exe scan).
To be really sure if it is scanning the D:\Bittorrent Downloads folder, you would need to change the report functions on the scan settings to include all files scanned and not just the limited errors and detections, etc. That would however increase the report file size and not something that you would want to leave on that report setting.
