Re: windows defender
if you have another antispyware program, it's not required. I still recommend having it as a backup antispyware/antimalware program. It's not a bad program and best of all it's free.
Desktop: Dell Dimension E510, 2.5GB RAM, Intel P4 3.0GHZ, 250GB HDD, Windows Vista Premium. Might not be the best, but the old girl is still running good.
