In the early 2000's I was working as an analyst for a VFX studio, and I had a meeting with the CFO first thing in the morning. At some point we needed to look at something on his computer, and he responds "we'll have to wait about 15 more minutes." "Why?" I ask, and he shows me every day when he turns his computer on the browser starts producing "pop under windows" at a rate of about 10 pr second, and that lasts for about 40 minutes. Shocked, I debate with him for a bit and he says they've tried every antivirus. I shake my head. When they stop popping windows he has a program that mass closes all of them and then he goes to work, using that same computer - and for studio finances. Blew my mind.
