iirc Windows Defender does a decent job. However, if you are a JavaScript developer, try to add node_modules to the exceptions, unless you don't care much about the performance hit.
I personally have stopped running antivirus on Windows a couple years ago. Since I run most, if not all, untrusted software in VMs, I didn't see the point of wasting performance. On the host, I only run Firefox and Steam/Epic games.
I then moved to Linux and I have 2 GPUs; one for the host and one for VMs with games. But that's probably a different story.
Can't you re-use those emails? I use random email aliases almost everywhere, and I store them in bitwarden.
