Hi. First off, ALL hijackthis logs should be posted in the Security forum. You also need to make sure it is saved in its own permanent folder, not a temp one or on your desktop. Also be sure that all other browser windows are closed before scanning. If you haven't done so already, you could do scans with Adaware and Spybot and let them fix anything they find. After doing that, reboot, scan with hijackthis with all other windows closed, and post your log in the Security forum where one of the security experts can help you out. There have been several threads dealing with the DNS error/Cannot find server issue. While you are waiting you could look through some of them and see if any of the advice offered in those threads can help you any. Good luck!
