A week later, I got a new computer, put it together and installed Windows Vista. I also backed up some data from my older computer and put it on the new machine. Then I installed WoW, updated it to 22.214.171.124, set the realmlist, and started the game. STILL, I could not play the game, and message about the trojan appeared again. I installed Avast! on the new machine and killed the trojan again, which had obviously followed the back up data from the older computer. After killing the trojan, I started the game up again. This time there is no message, but I still can't connect to wowscape server. I have tried the website too, with no luck.
If your thinking, "The website is down, and server is down," think again. I can go to my cousins computer, who is connected to the same isp as I am (via a router), and he is able go to the WoWscape server and website with no problems. It can't be the router either, because I have even took my computer to a different house and tried it.
I hope this is fully clear. If you need more info. about my problem, and you want to help me (and I hope you do), ask me and tell me how to get this info. if it requires any computer skills beyond the level of intermediate. Thank you.
