Advice for Cleaning Up After a Trojan

I didn't have the greatest start to my week to be honest- both my reddit and steam accounts were compromised at the same time and someone ended up charging $200 to my card. Thankfully both of those issues are resolved now, and I finally found the culprit- a trojan! I ran multiple virus scans with both Microsoft Defender and Avast because I had a creeping suspicion that something wasn't right, but somehow they both kept coming back clean. I finally tried Malwarebytes tonight and got my answer: "Trojan.PyengyLoader".

Malwarebytes says it quarantined and deleted the threat, and I did some light poking around on this reddit and ended up installing and running HitmanPro, but I'm still feeling really on edge about the whole thing. Forgive me, this is my first time actually dealing with a virus and the fact it dodged multiple other scans definitely freaked me out. In your professional opinion(s), am I finally safe, or is there more I can/should be doing?

Additional information, if relevant: I've already changed the passwords on just about every account I've ever used and turned on 2FA anywhere that it was an option. I've also started backing up my most important files just in case I need to do a full reset of Windows, but I'd definitely prefer not to if it's an option!
