You might want to download and burn a recent copy of a SystemRescueCD or
another standalone rescue CD (PLoP with Avast, Knoppix-STD with Clam, Avira
System Rescue System, Linux Defender with BitDefender for Linux, Trinity
Rescue). Try as many as you like. All are free to download and use. Burn
them to a re-writable and you won't waste anything, but time. It is good
practice and it should help you to clean your Windows installation.
