Others have given good feedback…for less $75 do this…

  1. Upgrade your 1GB RAM to 4GB
  2. Buy MBAM Pro for lifetime license for $24 while it last…once v2.0 comes out this lifetime license will go away.
    You can run Avast & MBAM Pro both “active” shields…just make sure if you run scheduled scans put them at different times.

I assume by “fast PC” you are good on other resources.
I’ll hold my comment on “XP”. :slight_smile:
