hmm, if you really are not using squid and squidguard, then open the MCC (mandrake control center), system, services, and turn off the service you don't need.
I'm not sure which version of the Drake you are using, so I'm assuming it is 10.something.
Sometimes these things get installed and turned on during installation, and you don't even realize they are happily or grumpily running in the background.

wasting your cpu cycles from more important things, like Tux Racer!
