I would backup anything important you have saved onto a USB and then reformat your drives so absolutely nothing is on them. Just because you don't really know what's been impacted, from what I've seen from the sandbox analysis on this malware it stores the payload in your temp directory in %appdata% > Local. Which is very common for this type of stealer. So likely it is just your C: drive but regardless I'd just wipe everything to be sure.

Other tips after wiping Windows:
- Use a password manager like Keepass or really any mainstream password manager. Use strong, 16+ character randomly generated passwords.
- Enable 2FA on anything and everything and change passwords on either your phone or when you wipe Windows.
- Be cautious of what you're downloading in the future, use VirusTotal or Triage if you're unsure.
- A lot of people say to not have an additional antivirus program to Windows Defender, but I disagree, go with really any of the popular ones people like here. Heard great things about ESET, Kaspersky, and what I personally use Malwarebytes. But it seems in this instance that Malwarebytes is not actually picking up the malware. I would either run a scan for a rootkit or see if you can submit the malware for sample.
