Having never experienced a virus in almost 20 years continuously online with multiple networked Macintoshes, I must say it sure doesn't sound like any fun.

I'm an IT Manager. Got hit with the same one at home, on multiple machines. In-laws also got hit with it. One of my technicians swears by MalwareBytes free version. No, it won't catch the virus in advance, but it will "clean" it out every single time. Just boot into safe mode, run the scan, and it will find it. He promises me.

Just wish I knew about it before spending all that time reimaging 4 computers!
