Is there any way to detect this virus? One of the computers at my job suddenly has the CPU light on all day and is very slow. It's probably something else, but if there's a common way to check for this virus I'd like to know.

Check the task manager for high CPU usage. If its poorly made it'll be there.
Also check the startup folder and the run registry keys, make sure nothing suspicious is there.
Scan with malwarebytes, should pick anything you can't catch up

Hardly needs to be poorly made - it's not easy to fake the CPU usage, unless you install a rootkit. And even then the sound of your fans blazing is pretty much a dead giveaway.

There you go. Undetectable silent miners.

Blazing fans? In your dreams. A silent miner takes about 30% of your CPU usage.
Then again, with ten thousands silent miners within a simple botnet, no need for maximum CPU usage

Can't see any that would be "undetectable" in that it wouldn't show up in Task Manager. You'd still need a rootkit for that - doable, but probably above the level of most script kiddies.

Of course you can throttle the usage down, but then you'd need 3 times more PCs to accomplish the same task (and in case of mining Bitcoin with CPUs scenario, that'd make your venture even more worthless).

And it's probably still detectable via a benchmark.
