Assisting someone with a Mac that won't boot. So, although we'll probably support this at some point in the future, it's not a high priority and it'll probably only work within certain parameters to avoid damaging sensitive data.

It's never a good idea to start messing with your backups, and if you were to remove something from a Time Machine backup using third-party software - or even manually removed something using the Finder or the Terminal - that will wreck your backups.

Especially since malware that might be on an external drive cannot get installed on a Mac, via any currently known method, by simply connecting the drive to the computer. That's simply not an issue in this day and age where everything malicious on Macs is designed to be downloaded and explicitly opened by the user. First, malware almost never gets onto a Mac from an external hard drive.
