NO!
I think you misunderstood. There were two questions.

  1. When I installed avast! and told it to scan my phone (default settings), it appeared to run (the scan time kept increasing) but it never indicated that it had completed the scan and showed 0 object scanned.
  2. I tried to tell the program to only scan one folder and the same thing happened as above. THEN I noticed that there did not seem to be any way to go back to the default setting of scan ALL storage folders. I could only select a specific one.
