I remember a particular person coming to me with malware on their laptop, I asked him what he had been doing, did any dodgy sites open up in the browser etc. He said he didn't look at pron or anything like that. Hmmm..too much information there and now i'm suspicious. Nuked it and gave it him back. A few days later i'm walking past his office and the whole screen is flashing multiple colours with a a single word in the middle of the screen. The word was SEX.
