    <p><strong>Reproduction steps: Run a selective scan of the C drive. Observe AVP CPU threads.</strong></p>
    <p><span></span></p>
    <p><strong>Actual result: Only about 4 out of 24 logical CPU threads/cores used. There are more threads created, but these do not process any files for the selective scan (4.16% = 1 core maxed out).</strong></p>

    <p><span></span></p>
    <p><strong>Expected Result: All 24 logical cores used, or at least the 12 physical cores (depending on SMT/Hyperthreading use).</strong></p>

      <p>@timur-born, hello!</p>
      <p>It's by design. Scan has 4 running processes  so 4 logical threads is enough. We don't plan to use all PC's resources for tasks,</p>
