[Rubidium]

Hi there,

I was wondering if I could get someone to talk me through the removal of a Zbot infection. I'd normally roll on with this myself, but I'd rather not take any chances as the computer I'm fixing is occasionally used by a family member for banking and shopping. The standard online solution suggests terminating svchost.exe processes, then deleting the offending registry entry as the computer is about to shut itself down automatically in order to prevent it from rewriting sdra64's entry into the registry.

Operating system is Windows XP Media Center Edition, should be fully patched, the browser of choice is Firefox and the fault was reported to me when it was picked up by AVG Free in an overnight scan. I've run MBAM and HijackThis to generate some logs and general diagnoses. I've also isolated this connection via a little detective work with ProcExp and TCPView - Googling the IP address points towards a Swedish registrant and is connected with Zbot attacks:

svchost.exe:900 TCP (snipped name).home:2446 95.143.192.16:http CLOSE_WAIT

Thanks for any help you can provide with this. If there are any diagnostics you'd like to run in order to further document this piece of malware, I'd be happy to run them and send the results along.

The HijackThis and MalwareBytes logs are as follows...

Bumping this after a day as recommended in the Welcome Guide. Any advice would still be very much appreciated!

Edit: Booted to a Linux CD and manually removed the file, then booted into safe mode and clipped the registry entry. Watching traffic on TCPView and the entry's gone. Malwarebytes has cleaned up the rest of the related files and they've stayed away. AVG scan so far is coming back completely clean.
