AdAware, Spybot S&D and CPU cycles

In addition to AVG, I run AdAware and Spybot on my Win2K machine: 1,33
Athlon with 512 megs of memory on a dial-ip connection. I notice that
running AdAware and Spybot takes takes up 99% of processor capacity,
with some variation. Why so processor intensive? Is this normal?

dont know about spybot but ad-aware is processor intensive during a scan,
but while fiddling in its gui with settings and what not, 0-1% cpu

ad-aware running at 70-99% cpu a in depth file scan of windows, and
documents and settings, 40280 objects, took 2mins 42 here

ad-aware running at 10-30% cpu (had another process running 70-90% cpu to
throttle ad-aware), took 6mins 22, so, im happier with it taking as much cpu
as possible if it finishes the scan much quicker

with in-depth turned off same scan takes 7 seconds
