Please use a backup solution as this is a fundamental part of security for the OS, ransomware and your personal files.
For second opinion scanner(s) you can use:
- Malwarebytes Anti Malware - deals with adware & PUP
- Zemana Anti Malware (Portable or non-portable) - worms & everything else
- Norton Power Eraser - when you know there's an infection on the machine
- Emsisoft Emergency Kit - great for everything
Thanks for sharing, the rest of your config looks great!
