How can I remove a Trojan.Ciusky.Gen.13 virus?

You should ask these "professional Mac people" exactly what virus a Mac can get.

/Volumes/com.apple.TimeMachine.localsnapshots/Backups.backupdb/Beastmaster

Outstanding points indeed...I intend to delete my AV software (Bitdefender) ASAP. That said, how do we go about removing this **** trojan from our Time Capsule?

Hello again Vanessa444,

I'm not sure what the "Beastmaster" is, but I know that your antivirus software shouldn't be doing anything with it. Those are all internal Apple data structures. There is a greater risk in corrupting your backups than in protecting you from any viruses.

I can't say much about the problems with your Mac. You've only said a few hints about that. But those problems likely aren't that different from your virus problems. Few people really know anything about Macs. That includes people who sell antivirus software. It is simply impossible that a file having a path of "/Volumes/com.apple.TimeMachine.localsnapshots/Backups.backupdb/Beastmaster" can do any damage to your Mac. The Mac just doesn't work that way. All that any of those antivirus programs do is scan your hard disk, and apparently your backups, for any files that match their "signatures". Those "signatures" are often wrong and match files that aren't a problem. Even worse, they are almost always based on Windows software.

So, the answer of why antivirus software works well on a PC but doesn't on a Mac is pretty simple. How well would software that only protects against Mac malware work on a PC? Not very well, I would bet. Well, that is the way PC software works on a Mac. You might see one or two reports of someone claiming that it found something. But quite often, you will see Mac users running popular antivirus software right alongside the most popular Mac malware. The general consensus is that antivirus software causes more harm among Mac users than the malware. There are a couple of Mac anti-malware apps that are effective, but you don't hear much about those. That is because they are effective and don't cause much trouble. One of the biggest Mac security problems is fake software and scam software. Much of it claiming to be antivirus software.

This thread is a good example of the practical problems that Mac users face. If you did actually have adware or malware, it would be easy to identify and remove. But trying to get people to remove problem software, or convincing them that they've just been scammed, is very difficult.
