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.

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.
