Not specifically Taiwan related, but a couple of links I have found very useful:
www.grc.com (Steve Gibson, internet security “guru”)
(and for balance grcsucks.com)
www.mailwasher.net (pre-screen your emails)
www.zonelabs.com (free and effective software firewall)
Since discovering this lot about three years ago I have had no problems with viruses hackers or any other nonsense. Of course a regularly updated virus scanner is a must. I’m using Norton 2002 at the moment and finding it very good. McAfee used to turn itself off every so often which was disconcerting. Steve Gibson’s site is very interesting, although check out the grcsucks site to get a slightly different slant…! Anyway, hope this is useful.
