Custom Scan will not point correctly

Have the free version on a desktop with two drives C &E. Created a custom scan for USB drives that appear as drive F. Launched the USB scan to find that it is pointed to drive C. Pointing to drive F was confirmed once again. Is this a known issue? Seeking guidance on resolution.

If you have the option to scan memory on start enabled ( it is enabled with default settings ), it will scan all running processes and also for every process loaded .dll’s and such, and then proceed to the designated scan location. That’s why you see it scanning some windows and program files first.

Try to un-check the memory scan option for manual scans and see it the issue persists.
