Hello,
My AVG Free home edition gave me the news today that my services.exe is infected with trojan dropper.generic_c.MMI. A full AVG scan also indicated and alleviated the following infections
"";"C:\Windows\Installer\{c5a8250a-3c0e-7511-5fec-114d29070370}\n";"Trojan horse BackDoor.Generic15.BHGZ";"Moved to Virus Vault"
"";"C:\Users\Wereducky\AppData\Local\{c5a8250a-3c0e-7511-5fec-114d29070370}\n";"Trojan horse BackDoor.Generic15.BHGZ";"Moved to Virus Vault"

I am running Windows 7 Professional 64-bit SP1, using Firefox, and protected with AVG free home ed. and Spybot S&D. Firefox has been attempting to redirect to some other pages since early this morning, but spybot appears to have the targets blocked. I have noticed no other effects yet besides AVG reminding me of the services.exe infection periodically.

Google led me to the forum post of another fellow in the same predicament this morning here: http://www.bleepingcomputer.com/forums/topic459740.html. I have followed narenxp's initial post, running TDSSkiller, aswMBR, and ESET and want to post my results here in case a more discerning eye notices a difference in the logs that would prompt different advice from that posted there, but I will continue to follow the advice given there until told otherwise.

AVG resident shield has also detected the following infections while scanning with the suggested tools, though the tools were allowed to complete
"Trojan horse Generic28.ANIC";"c:\Windows\assembly\GAC_64\Desktop.ini";"Infected";"7/8/2012, 1:18:04 PM";"file";"C:\Program Files (x86)\ESET\ESET Online Scanner\OnlineCmdLineScanner.exe"
"Trojan horse BackDoor.Generic15.AXLA";"c:\Windows\assembly\GAC_32\Desktop.ini";"Infected";"7/8/2012, 1:17:59 PM";"file";"C:\Program Files (x86)\ESET\ESET Online Scanner\OnlineCmdLineScanner.exe"
"Trojan horse Generic28.ANIC";"c:\Windows\assembly\GAC_64\Desktop.ini";"Infected";"7/8/2012, 12:28:19 PM";"file";"C:\Users\Wereducky\Downloads\aswMBR.exe"
"Trojan horse BackDoor.Generic15.AXLA";"c:\Windows\assembly\GAC_32\Desktop.ini";"Infected";"7/8/2012, 12:28:15 PM";"file";"C:\Users\Wereducky\Downloads\aswMBR.exe"

Seems like the last time I saw the Sirefef trojan, I had also been recently searching for jobs and submitting applications, makes me wonder if one of their websites is infected without their knowledge or it could just be coincidence.

Thanks for any help you can provide in advance.

You're infected with ZeroAccess rootkit.
That will require elevated help.

Please follow the instructions in ==>This Guide<== starting at Step 6. If you cannot complete a step, skip it and continue.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<== Please include a description of your computer issues, what you have done to resolve them, and a link to this topic.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

It would be helpful if you post a note here once you have completed the steps in the guide and have started your topic in malware removal. Good luck and be patient.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.

I think that hat should be white, but well I guess green isn't black either :) Quick question for you, should I keep the infected computer shut down while waiting for a response over there, or would restarting be more damaging than leaving it be. I ask because I already restarted once and the random advertising redirects are now working as intended by the author of this bug.

In case of this nasty rootkit I'd keep your computer shut especially if you have some sensitive info there.
