Re: Unlike ext4, btrfs provides "file security against viruses and malware"
Not exactly, but it supports 'snapshots' as it is a copy-on-write file system. So malware that trashes files on your Z: drive or whatever will cause the file system to write the malicious changes to new blocks on disk. Once you find out, and have killed the infection, you can go back to the snapshot time and get your previous files' contents back.
Assuming you snapshot regularly and notice the infection before those snapshots get overwritten.
