trojan horse agent_r.xj, and probable TDL3

I was first notified of the virus from AVG, a trojan horse agent_r.xj. I noticed a very similar situation from this thread (http://forums.majorgeeks.com/showthread.php?t=228298), where the first post is as it is for me (the infected svhost.exe, and explorer.exe

C:\WINDOWS\system32\svchost.exe (####):\memory_001a0000
C:\WINDOWS\system32\svchost.exe (####)
C:\WINDOWS\explorer.exe (####):\memory_001a0000
C:\WINDOWS\explorer.exe (####)

, and eventually discovered a rootkit: tdl3 which was detected with Unhackme. I downloaded TDSSkiller.exe but I kept running into an error when the installation process hit 80%. So I came to this forum, during which I have progressively received numerous AVG notifications of viruses (OMO.exe, OME.exe, etc.) and downloaded, installed and ran the appropriate cleaners, and prepared their respective logs with the hopes that someone here can help me. (I initially received the virus notification after accessing a veho link to Banksy's documentary, Written on the wall :/ , serious bummer). Currently, I still have my AVG uninstalled, I'm assuming I should reinstall it, or perhaps install the lastest of Avast?

 

Here is the last of the logs... also should mention this is a windows xp pro 32-bit thanks

 

hey, thanks
I was wondering whether it had to be the same windows xp cd that was used to install it, because I don't have the cd, a friend gave me the computer. Would a windows xp home ed work just the same (installation cd that is)?
