Trojan DNSChanger [usually 82.225.110.12], keeps coming back; i can't access microsoft updates Options

[darkheart]

i'm running windows XP sp2, and my computer is the third in a series of computers connected to a D-Link DI-604 router.

sometime last week i stupidly, STUPIDLY ran a WMV file that asked for a codec to be installed, even more stupidly installed the codec, and here we are. since then i've been getting "popup.adv.net" popups from every site i go to, and my dns settings keep getting reset to 85.225.110.12 and i cannot download microsoft updates [can access all pages, but i get a "the page requested cannot be found" when i try and download]. i've since installed NoScript for Firefox 3.04 to keep the popup scripts from running.

i also found a hidden "resycled" folder and its accompanying autorun.inf in each of my partitions and my flash disk, deleted them all.

there was also a hidden "yahoo!" folder in my Documents and Settings Application Data folder before the Malwarebytes scan, but it's gone now.

i don't know about the second computer linked to the router, but the main one does not seem to have the popups [even without the NoScript]. however, it cannot download microsoft updates either. ran Malwarebytes on it and it also found the DNSChanger trojan.

i've run sdfix and smitfraudfix, both of which removed a DNSChanger trojan. Malwarebytes also removed it last night, and this morning, and this lunchtime, everytime i'd run it. but it keeps coming back.

the logs posted are for my computer.
