Very nice and informative posts Swift and Nero.
I didn't add info about firewalls and anti-hijack software, but I have recently experienced that I should have..
Somehow my DNS IPs had been changed into something completely wrong, and whne I tried to access certain sites (cnn, yahoo, and MY OWN SITE!!) I just got forwarded to www. www. milforum. com. org etc.. (com.org added to every URL) DON't click on that link, they don't deserve the attention!
I first thought i was spyware, but later found out that it was my DNS settings that had been "hijacked"...
