Unfortunately, you haven't shown that the CPU actually consumed is going up by 243% or any significant fraction thereof. Admittedly, A/V products are slowly taking more and more resources, but nowhere near a Moore's Law rate. Do some benchmarking. Time how long it takes to scan a collection of 500 or so random files using a 2007 version of your favorite A/V software and signatures, and time how long this week's version take. The difference between the two numbers is the CPU you can "get back". I guarantee it has no relationship to the 243% you're complaining about (for starters, even if it *was* gaining 243% a year, that's a 243% grown rate of the 5% or so your anti-virus uses, not of your entire CPU capacity. > I'm not analysing infections, I'm analysing "new threats" (as defined > by Symantec). Read Thor's description of the difference between threats and risks. Defending against threats doesn't consume additional CPU. Defending against risks *may* consume additional CPU.
