It's likely that he accidentally installed one of these 'security' programs (or had it installed), which spiraled out of control from there.These hijacks didn't appear to be able to do much beyond slow down his machine with endless failed attempts to run a program - the process didn't have admin permissions, so it couldn't execute a thing from the library. And worst of all, they'd seemingly added a bunch of nonsense files into this computer's Library folder, with random folder names like 'prestidigitation' and 'beeswax'.Now, I want to preface: I'd never seen an attack like this on a Mac before in my life, and finding this kind of full-Mac hijack is very rare. Upon further investigation, I found a couple of self-professed 'Mac security programs' that popped up, demanding money to 'clean your Mac from junk'.Spoiler: These programs were the junk. It was clear to me that his browser had been hijacked.We got rid of the browser hijack pretty quickly - I suggest using Cella's excellent how-to if you ever run into a browser hijack yourself - but the slowdowns were more curious. My father-in-law's MacBook Pro had been running into curious slowdowns for a two-year-old laptop and he kept on seeing weird sites taking over his Safari and Firefox search bars.
