Actually, running adaware in safe mode is quite easy. Safe mode is just a way for windows to start that prevents all of the drivers and programs from starting up. Normally, no spyware can take control of your system while you're in safe mode.

So, reboot your computer. Wait about 2 seconds, and then start hitting F8... hit it maybe once per second until you see the Safe Mode menu come up. Choose safe mode, and then windows will start up like normal... minus drivers and programs. Then, run adaware, and reboot.

If you have trouble getting into safe mode, just reboot and try again (I hit F8 at the wrong time sometimes too).
