Problem with Trojan.DNSChanger removel

Recommended Posts

I am remotely troubleshooting problems on a client's laptop. Symptoms were odd DNS redirection errors (browse to Windows Update sends you to Google, AVG anti-virus update downloads won't work, etc.). Machine is a Toshiba laptop running XP, conncted to internet withVerizon broadband

I ran mbam and it found and said it removed Trojan.DNSChanger (I'll post logs below). Afterwards the DNS redirection problems continue though, and am not sure what to do net (HijackThis log does not show anything obvious, AVG scan came up negative, additional mbam scans (including full scan) show nothing. Have also cleared System Restore area, flushed DNS cache, rebooted, etc.

One issue is that because of the DNS redirection, mbam can't update itself, so we are stuck at the database version 1654 from 1/14 and can't get current. Is there any way to manually get the update (I can download files from my machine and upload them to the problem machine if I knew where to get it).

Here's the mbam log, and a current HijackThis log. Thanks for any suggestions.
