aVast refuses to install

Infected machine actually had a service on it claiming to be aVast however even after cleaning the machine with multiple products I cannot get aVast Pro to install. I have booted into Safe Mode and ran the uninstall cleanup tool which says it removed everything however the error below is given during an aVast install:

Some infections prevent antivirus installation.
Read the instructions, download and burn (maybe from another computer), finally use one of this rescue CD’s:

  1. Avira
  2. Kaspersky
  3. BitDefender
  4. F-Secure
  5. Dr. Web
