The maker of Malwarebytes is reporting that the software updating site, MacUpdate, is unwittingly distributing software that contains a virus designed to use your Mac's CPU to mine for cryptocurrency.

Fortunately the free version of Malwarebytes can detect and remove this virus.

Thanks for the heads up. Malwarebytes reported no problems for me. Also, I never download anything directly from MacUpdate. Instead, I either go directly to the developer's site or launch the app and let it update by itself.

I've seen things I suspect of doing that popping up infrequently at random places. I'll visit a website and while the page is up I'll hear my laptop's fans start spinning up. Open activity monitor and find some web process running lots of CPU.
