Greetings to one and all.I'm new to this so bear with me.When doing a full system scan with w/defender,it literally uses 90+ cpu and the scan tends to last for approx 1hr 15mins in this state. I'm using w/xp home sp2 with norton net sec2006 plus ad-aware.The defender scan sometimes picks up Exploit:Win32/Wmfap which defender does remove.
Offline disable norton security suit and run windows defender and see how much cpu usage you have. Obviously re-enable norton when you finish the test. Might not be defender that's using so much of your cpu.
