Noun - One of the many people who think that their Windows PC is 100% secure because it came with McAfee pre-installed. Usually ignorant, technically-inept and sometimes like to complain about how slow their computer is, typically blaming the slowness on some irrelevant factor such as their ISP when the true cause is McAfee.
Ignorant person: "Holy fuck my computer is slow as tits and everything keeps crashing!"
Computer guru: "You probably have a trojan."
Ignorant person: "Nah, I got McAfee."
Computer guru: "McAfee won't detect shit. And when was the last time you updated it?"
Ignorant person: "I dunno, the internet wouldn't work when it updated so I turned it off."
Computer guru: "OK, click actions then request remote assistance so I can work on the comp for you."
*Installs CCleaner, Malwarebytes, ASquared and SpyBot S&D - 5 hours later finds and removes 27 different adware, 8 spyware and 3 trojans then replaces McAfee with Avast*
Happier ignorant person: "Holy fuck it's faster."
Computer guru: "Of course it is you McAfee'tard!"
