No, Peng..it's not that complicated. Really. Read again what I use. I do have Adaware and have run it once a month or so and it never ever finds anything. :: And there is nothing wrong with running automatic Windows Update. The paranoia about that is really quite mind boggling to me. Filesize of the downloads was never a problem for me even on dialup. It works in the background, uses bandwidth only when it's available and stops and continues the transfers as necessary without interference. As for protection from the Blaster worm, even if you did NOT do the windows update, you would be protected from it by the XP firewill. And that firewall is the simplest thing. Off or on. Full stealth mode. The netbios thing is a one-time deal. GRC has instructions. Do it once and never worry about it again. We've been running virus checkers for years. So what's the big deal about that. I don't use Mailwasher or any spam filter. They add needless complications and sometimes filter out what you don't want filtered. I was getting up to 300 spams a day on my old 9-year-old email address. All to my inbox and it was easy enough to delete 'em.
